1、英文及译文翻译英文原文:AccumulatorsAn accumulator is found in many hydraulic systems. As the n ame suggests, it is a storage device. The various types of accumulators are studied in this chapter.A simple accumulator is sometimes used in household water system. It may con sist of a tee with a side branch pipe t

2、hat is capped. The air that is trapped in the side branch pipe is compressed, and the n acts like a compressed spri ng. As a faucet is either ope ned or closed quickly, a sudde n cha nge in pressure and flow occurs. The trapped air acts as cushi on, or shock absorber, to preve nt water hammeri ng in

3、 the pip ing system.The storage batter in a car is a typical example of an electrical or chemical accumulator. Chemical en ergy is stored in the batter is not in use. The stored chemical en ergy is con verted into electricity that is used to start the engine.Hydraulic AccumulatorsA hydraulic accumul

4、ator may be used for a variety of purposes. Some of its uses are: ( 1 ) as a shock absorber; (2) to provide oil makeup in a closed system; (3) to compensate for leakage in a system; (4) to provide a source of emerge ncy power in eve nt of failure of the no rmal power supply;(5 ) to maintain steady d

5、elivery pressure over a period of time without keep ing the pump operat ing con ti nu ously; and (6) as a tran sfer barrier device to separate the oil from some other fluid in the system.Types Of AccumulatorsAccumulators may be divided into three gen eral types: ( 1 ) weight-loaded, (2) spri ng-load

6、, and (3) air-or gas-type accumulators. The air-or gas-type Accumulators can be subdivided further into the separator and non-separator types.Weight Loaded or Gravity TypesThe weight-loaded or gravity-type accumulator consists of a cylinder, a movable position, a ram or plun ger, and a weight. The d

7、ead weight ( which may be placed in a container) may be con crete, iro n, steel, water, or other heavy material. The positi on should have a precisi on fit in side the cyli nder in order to reduce leakage. The inner cyli nder wall should have a honed or ground finish in order to reduce fricti on and

8、 wear. As hydraulic oil is pumped into the cyli nder, the pist on pushes the weight to a higher level. Thus the pote ntial or stored en ergy of the weight is in creased. The en ergy stored in the weight is released in the dow nward moti on as it is required by the dema nds of the system. An accumula

9、tor of this type may be custom-built for a particular in stallati on. The weight is adjusted so that the ram rises whe n the fluid pressure reaches a set level. The travel of the ram can be con trolled by an arran geme nt of a cam on the plun ger and limit switches. The gravity force of the pist on

10、on the oil provides a n early con sta nt oil pressure level forthe full stroke of the piston. By providing adequate piston area and ample length of piston stroke, a large volume of fluid can be supplied at high pressure. A sin gle large accumulator may provide service for a nu mber of differe nt mac

11、h in es.Spring-loaded TypeA spring-loaded type of accumulator is illustrated. This device consists of a cylinder, a piston, and a spring. One or more springs may be used. The springs may be arranged to provide various adjustments by means of bolts. As the oil is pumped into the accumulator, the pist

12、 on or plun ger compresses the spri ng; The en ergy stored in the spri ng is released as it is required by the dema nds of the system. The pressure on the oil is not con sta nt for all the positi ons of the pist on, because the spri ng force depe nds on the moveme nt of the spri ng. Usually, this ty

13、pe of accumulator delivers on ly a small amount of oil at low pressure.Air or Gas TypeHydraulic fluid or oil is n early in compressible. This means that a large in crease in oil pressure results in only a small, or n egligible, decrease in the volume of oil. On the other hand, a large in crease in a

14、ir or gas pressure results in a large decrease in the volume of the air or gas. Relatively speak ing, hydraulic oil is less elastic or spri ng-like tha n air. Oil cannot be used effectively to store en ergy by compress ing it, whereas air or gas can be compressed to store en ergy. Thus, one gen eral

15、 type of accumulator used gas or air, rather tha n a mechanical spring or a weight, to provide the spring-like action. Air or gas types of accumulators can be divided into two subdivisi ons: (1) the non-separator type, and (2) the separator type. In the non-separator type of accumulator, the oil is

16、in direct con tact with the air or gas. In the separator types of accumulator, either a solid or a flexible barrier is placed betwee n the oil and the gas to separate the two differe nt types of fluids.Non-separator TypeA non-separator type of air or gas accumulator con sists of a fully en closed cy

17、li nder, adequate ports, and a charg ing valve. A porti on of oil must be trapped in the bottom of the cyli nder before this type of accumulator can be placed in operator. Air, n itroge n, or an inert gas is the n forced into the cyli nder, and the accumulator precharged to the mi nimum pressure req

18、uireme nt of the system. A so-called free surface exists betwee n the oil and the air or gas. As a greater qua ntity of oil is pumped into the accumulator, the air or gas above the oil is compressed still further. The energy is stored in the compressed gas, and it is released as required by the dema

19、 nds of the system.This type of accumulator should be moun ted in a vertical positi on, because the gas must be reta ined in the top of the cyli nder. To preve nt the air or gas being exhausted into the hydraulic system, only about two-thirds of the accumulator volume can be used for the air or gas

20、volume. Approximately on e-third of the rema ining accumulator volume should be reserved for the oil, to prevent the air or gas from being drawn out of the accumulator to the hydraulic system. Aerati on, or mixing, of the oil or air or gas may result in diminishing the precharge of the accumulator.

21、If the air or gas is absorbed by the oil, the accumulator requires an air or gas compressor for the precharg ing operati on of the accumulator.Separator Type ( with piston)A separator type of accumulator with a free or floati ng pist on act ing as the barrier betwee n the air or gas and the oil is i

22、llustrated in Figure. High-pressure air or gas is charged into the space on one side of the pist on, and hydraulic oil is charged into the space on the opposite side. The tube should be mach ined with precisi on. The pist on pack ing keeps the oil and gas separated.This type of accumulator may be in

23、 stalled in any positi on. The preferred positi on, however, is to place the cyli nder axis vertically, with the gas connection at the top. The weari ng actio n of the pack ing between the piston and the cylinder should be checked after extended use, because this may result in sig ni fica nt leakage

24、.A floati ng pist on with in a cyli ndrical accumulator is illustrated in Figure .In the desig n, the double-shell con struct ion provides a pressure-bala need inner shell that contains the positi on and serves as a separator betwee n the precharged air or gas and the work ing hydraulic fluid. The o

25、uter shell serves as a gas container. Rapid decompressi on of the precharged air or gas, result ing from a rapid discharge of the work ing hydraulic fluid, provide a coola nt for the en tire cork ing area of the inner shell. Pressure bala ncing ports in the pist on provide equal pressure to either s

26、ide both rin gs; this preve nt pressure lock betwee n seals.Separator Type (with diaphragm)A diaphragm-type accumulator involves two hemispheres that are made from steel forgings. The hemispheres are locked together and a flexible, con voluted, rubber diaphragm is clamped around the periphery. An ai

27、r or gas precharge is applied to one of the two hemispheres; oil, un der pump pressure, is applied to the opposite hemispheres to compress the sir or gas charged. As the air or gas is compressed, the pressure rises; then the gas acts as a spring. Oil pressure and gas pressure are equal, because the

28、separating member is flexible.Bag TypeThe type, or bladder, type of accumulator is a seamless steel shell that is cyli ndrical in shapeand spherical at both en ds. A gas valve is located at one end of the shell and ope ns into the shell. A large ope ning through which the bag can be in serted is loc

29、ated at the opposite end. The bladder is made of syn thetic rubber and is pear-shaped. The fully en closed bladder, i ncludi ng a molded air stem, is faste ned by means of a lock nut to the upper end of the shell. On the opposite end of the shell, a plug assembly containing the oil port and a pop pe

30、t valve is moun ted. The accumulator cannot be disassembled while a gas charge is in side the bag. The accumulator should be in stalled with the end that contains the air at the top to avoid trapp ing the oil whe n discharg ing.ContaminationAs with the other comp onents in a hydraulic system, care s

31、hould be take n to avoid con tam in ati on whe n installing the accumulator. The accumulator should be cleaned completely before installation in the system. Si nee an accumulator usually forms a dead-e nd in the pipeli ne, it may not be flushes as well as some other comp onents duri ng system operat

32、io n.The pist on-type accumulator can be studied to better un dersta nd accumulator con struct ion. The pist on may be sealed with an O-ri ng groove, caus ing wear or damage to the O-ri ng and allowi ng the gas charge to leak into the oil. An arran geme nt in which an O-ring seal is placed betwee n

33、Teflo n pist on rings provides a means by which the pist on rings can scrape con tam inants from the cyli nder walls, and thus protect the O-ring seal. It is a good practice to in stall a filter in the air or gas charg ing system of the accumulator.Accumulators In SystemsThe accumulator is ofte n in

34、 stalled in a hydraulic system to absorb shocks. The hydraulic oil from a pump is piped to a four-way valve, which directs the oil flow to a cyli nder containing a pist on. If the valve is closed quickly, the sudden stoppage may result in oil shock waves, or a hammering effect. A violent hammeri ng

35、acti on may damage the fitt ings and pip ing. The accumulator is capable of absorb ing the shocks, thus protect ing the en tire system.During periods whe n no flow of oil is required in the hydraulic system, pump delivery can be retur ned, or bypassed, to the reservoir at low pressure. This arran ge

36、me nt serves to reduce electric power requireme nt, oil heati ng, and wear of the moving parts.The accumulator can be used as a power-saving device. A piston provides a loading force-as for a clampi ng operati on or a rolli ng mill operati on, in which the force moves only a short dista nee. After t

37、he oil pressure is built up at the pist on face, the accumulator can supply the loadi ng force for a period of time. During this period it is unn ecessary to keep the pump deliveri ng at high pressure. Therefore, an uni oad ing valve is provide to retur n the pump delivery to the reservoir at low ou

38、tlet pressure. During the uni oadi ng process, the pump discharge pressure is a low level, while the accumulator pressure is at a high level to provide the loadi ng force. Thus, the accumulator is a power-savi ng device, and also provides for absorpti on of shock waves.蓄压器储压器在很多水压设备中都能发现有一个蓄压器。正如它的名

39、字所暗示的,它是一个存储设备。在这一章中要学习各种不同种类的蓄压器。有时候在家庭存水设备中就会用到一个简单的蓄压器。它可以被认为是一个球坐和一个被覆盖住头的分支管组成。空气就在那个被盖住的分支管里,然后按压。随着盖帽的迅速打开盖上, 气压突然改变,然后就产生了气流。里面的空气就充当了气垫或者是减弱冲击的缓冲器,用来防止管子里的水溢出。汽车里的存储设备是一种电的或化学成分的蓄压器。不使用的化学能储存在储存器里面。储存的化学能被转化成电能后供发动引擎使用。水压蓄压器可能被用作不同的目的。它们的一些用途有:(1)作为一个减弱冲击的缓冲器;(2 )在一个关闭的系统里提供汽油;(3)补充系统内的渗漏物;

40、(4)在不能达到正常的引力情况下,提供紧急 能量的来源;(5)当泵不能继续运转的时候,在一段时期内维持传送过来压力的稳定;(6)作为一个传输障碍物,在系统中将汽油和其他液体分离。蓄压器的种类蓄压器一般分为三种类型:(1 )重量装载类型,(2 )弹簧支撑类型,(3)空气或气体类型。空气或 气体类型的蓄压器又可以进一步划分为分离的和非分离的。重量装载或重力类型重量装载或重力类型的蓄压器是由一个圆柱体,一个可移动位置的撞击物或活塞和一个重物组成。 那个无生命的重物(可能被放在容器中)可能是具体的铁,钢,水,或其他重质材料的东西。在圆柱体 里的那个位置要固定准备,用来减少渗漏物。圆柱体的内壁上应该有一

41、个磨砂的或毛的物质来减少摩擦 和磨损。当水力油抽入圆筒,活塞推挤重量对高水平。因而增加重量的潜力或储能。当它由系统的要求,需要在重量存放的能量在向下运动被释放。这个类型蓄压器也许是定制的为特殊设施。因为重量装载是被校正过的,所以当液体压力到达设定的值的时候,活塞就会上升。撞击物的移动可能受放在活塞和计时器上的凸轮的控制。活塞的重力在油的为活塞的充分的冲程提供一个几乎恒定的油压水平。通过提供充分活塞区域和活塞冲程的宽裕的长度,大容量流体可以被供应在高压。一台唯一大蓄压器也许为一定数量不同的机器提供服务。弹簧支撑类型蓄压器的一种弹簧支撑类型被说明。这种类型是由圆柱、活塞、弹簧组成的。或许一根或更多

42、根弹簧要被用到。这种类型的蓄压器也许通过螺栓提供各种各样的调整。当油抽入蓄压器,活塞或柱塞挤压弹簧;当系统需要时,储存在弹簧内的能量就被释放。因为弹簧的力量取决于弹簧的运动,在油的压力为活塞的所有位置不是恒定的。通常,这种类型的蓄压器交付仅少量油以低压。空气或气体类型液压机液体或油是几乎不可压缩的。这意味着油压的大增量,导致只有一点点,或几乎不能地降低油的容量。换句话说,空气或气体压力的大增量,能导致空气或气体体积的大幅度下降。相对来说, 水力油比空气较不有弹性或象弹簧的。油不可能通过压缩它有效地用于存放能量,而空气或气体可以被压缩存放能量。因此,蓄压器的一种一般类型使用气体或空气,而不是机械

43、的弹簧或重量装置,提供像弹簧的作用。蓄压器的空气或气体类型可以被划分成二细分:(1)非分离器类型和(2)分离器类型。在蓄压器的非分离器类型中,石油是直接与空气或气体联系。在蓄压器的分离器类型中,一个坚实或一个灵活的障碍被安置在石油和气体之间分离流体的二种不同类型。非分离类型空气或气体的非分离蓄压器类型由一个充分的附上的圆筒、充分口岸和一个充气阀组成。 在此种蓄压器能被操作员使用之前,一部分油必须在圆筒的底部被困住。空气、氮气或者惰性气体然后被强迫入圆筒,蓄压器预加压力满足系统需要的最小压力。所谓的自由表面存在石油和空气或者气体之间。 当一个质量更好的油被压入蓄压器中,在油之上的空气或气体被进一

44、步压缩。能量存储在压缩气体中, 当系统需要是被释放。这种类型的蓄压器应该安装在一个垂直的位置上,因为气体必须保留在圆筒的上面。为了防止被用尽的空气或气体进入水压系统中,只有三分之二的圆筒的容量才能被空气或气体使用。剩余的三分之一的圆筒的容量是为油后备的, 为了防止空气或气体从蓄压器发挥出来进到系统中去。通风或者混合的油或空气或气体可能导致减少蓄压器的预压力。如果空气或气体被油吸收了, 蓄压器就需要一个空气的或气体的压气机来对蓄压器进行预加压。分离类型(带活塞的)带有自由浮动活塞的分离类型的蓄压器,在空气或气体和油之间是一个障碍,这在图中有被说明。高压空气或气体被加压在活塞一边的空间中,并且水力

45、油被加压在反面的空间中。应该用机器制造管与精确度。活塞包装使油和气体相分离。此种蓄压器在所有位置也许被安装。然而,首选的位置,是垂直安置圆筒轴,与在上面的气体连接。因为这也许导致重大漏出,应该在延长用途以后检查在活塞和圆筒之间的包装的佩带的活动。在一台圆筒柱型蓄压器内,一个浮动的活塞被用图说明了。在设计中,双壳构造的蓄压器保持内壳层压力的平衡。内壳层包含了分离预加压的空气或气体和工作液压机液体的位置和服务。外壳则作为气体容器。 被预先加压的空气或气体的迅速解压,起因于工作液压机液体的迅速放电,为内壳层的整个 塞住的区域提供蓄冷剂。在活塞的压力平衡口岸提供相等的压力给任一边两个圆环;这防止在封印

46、之间的压力锁。分离类型(带膜片的)膜片类型的蓄压器包含两个由钢锻造的半球。两个半球锁在一起,然后一张灵活,复杂,橡胶膜片在周围附近被夹紧。空气或气体预加压后被放到其中的一个半球里;油,在泵浦压力下,被放于相反半球来压缩填充的空气或气体。当空气或气体被压缩,压力就变大;然后空气就相当于是弹簧。因为分离的成员是灵活的,油压和气体压力是相等的。包类型这种类型的蓄压器是一根无缝的钢毛管。而这个包或者囊是一个圆柱体在有形的球状的两个末端。排气阀位于壳的一个末端并且打开入壳。 一个可以通过包插入的开口在相反的末端。 囊由合成橡胶制成 并且是梨状的。包含一个模塑的空气的阀杆紧附在囊上。 它通过螺帽被紧固在壳

47、的上端。在壳的相反方, 安装有一个包含供油港和流行石油阀门装置的塞子。 当气体加压是在袋子里面时, 蓄压器不可能被拆卸。 这种蓄压器应当安装在顶端有空气的部分,以免当释放时油被困住。污染当安装蓄压器时,在液压机系统中装有其他零组件时,应当注意避免污染。 蓄压器被安装到系统之前应当彻底的清洗。因为在管道内,蓄压器通常是一种固定的形式,因此,在系统运作是,它可能不能 像其他零部件那样冲洗。学习活塞式的蓄压器能更好的理解蓄压器的构造。活塞也许密封成0环凹线,0环封印安置在聚四氟乙烯活塞环之间,提供0环封印。在空气或气体的蓄压器系统中安装过从泵浦的水力油被用管道输送到一个四种方式的造成对0环的磨损或伤

48、害而且使得空气加压流入油中。 活塞环可能刮从圆筒墙壁的污染物的方法和因而保护 滤器是一种很好的练习。蓄压器在系统中蓄压器经常被安装在一种液压系统中来缓冲震动。阀门,指挥着油流到包含活塞的圆筒。如果阀门迅速被关闭,突然的停止也许导致石油危机波浪或者一个锤击的作用。一次猛烈锤击的行动也许损坏配件和管道系统。蓄压器能够承受震动, 因而可以保 护整个系统。当液压系统没有需要油流动的这段期间内,泵排量可以以低压返回或者被绕过,到水库。 这个措施能减少对电力和运动机件的油热和磨损。蓄压器可以使用作为力量挽救设备。活塞为夹紧的操作或轧板机操作提供装货力量,力量移动仅一个短的距离。在油压被加强在活塞面孔之后,

49、蓄压器可能在一段时间提供装货力量。在这个期间内泵浦持续交付在高压是不必要的。因此,一个卸荷阀是提供以低出口压力退回泵排量到水库的。在卸载的过程期间,泵浦释放的压力在一个低水平上,而蓄压器的压力在一个高水平上,来提供装货力量。 因此,蓄压器是一个力量挽救设备,并且提供冲击波的吸收。第八课数字信号处理器(DSPs)在很多情况下,模拟信号要被不同的方式处理,像过滤和光谱分析。由于对性能的要求,灵活性的需要和需要减少发展或测试的时间,设计模式硬件执行这些作用是可能的,但是变得越来越不实用了。换句话说,设计执行对信号的先进的分析的模式是难得。抽样一个模拟信号到数字式领域里的行为,和申请处理在使用计算的算

50、法的数字式版本并且在处理后可能恢复信号到模式领域的过程叫做数字信号 处理。处理器涌现了在为嵌入信号处理操作被专门研究的过去15年期间内,并且这种处理器称DSP,代表数字信号处理器。如今,有许多来自不同产方设计的数字信号处理器,每一种都是为特定价钱/性能/使用群体设计的。像德州仪器和摩托罗拉这些大型产商,即为特定领域提供特定的数字信号处理 器,像电动机控制或调制解调器,而且还提供一般的高性能的数字信号处理器,这中处理器能处理广域范围内的处理任务。 升级工具和软件也是可用的,而且有商家为数字信号处理做升级软件,这种处理器能够允许程序员用简的drag n drop统计分析法来处理复杂的程序算法。根据

51、下面的定点和浮点的体系结构,数字信号处理器或多或少被归入两个类别。定点设备通常起作用于16位的字,而浮点设备起作用于3240位的浮点字。不用说,定点设备通常更加便宜。另一个重要的体系结构的区别就是,当只有一台“通用”记数器,使他们相当棘手而且更加重要的处理时,定点 处理器只倾向于有累加器的体系结构。这使得C编译器本质上地效率低。浮点数字信号处理器更像带有寄存器组的普通的通用 CPUs。在市场上,有成千上万种不同的数字信号处理器,而且很难为某个项 目找到一个适合的数字信号处理器。最好的办法大概就是设定一个限制条件,然后和大的产商生产的处AT&T和模拟设备。DSP,然后被解码的样品必须转这种数模变

52、换(DAC )另惧有相同理器进行比较。数字信号处理器的四大产商是:德州仪器,摩托罗拉, 数模变换在MPEG音频解码情况下,数字式压缩的数据被投向执行解码的 换回到模式领域和发生的信号被投向放大器或相似的音响器材里。THD (总谐波畸变),数名字的电路执行。不同的数字信号处理提供不同的操作和质量,如测量由位的 字,线性、速度、过滤器特征和其他东西。德州仪器的TM320家庭数字信号处理器TM320家庭型的包括定点,浮点,多重处理机数字信号处理器(DSPs)和定点DSP控制器。TM320的数字信号处理器有一个特别为实时信号处理明确地设计的体系结构。DSP控制器的C24x系列与控制器外围设备结合,这种

53、实时处理能力是创造控制系统应用的一种理想的解答。以下特征为在广阔领域中使用TM320家庭型提供准确的应用程序选择:-非常灵活的指令组-固有操作的灵活性-高速处理-创新平行的体系结构-成本实效有TM320家庭型数字信号处理器设备的一代都有一个相同的CPU结构,但芯片记忆和周边配置是不同的。使用新的芯片内存和外围设备组合的附带设备能满足在全世界的电子市场上的不同领域的需 要。通过在一个单独的芯片上安装综合的记忆卡和外围设备,TMS320设备减少了系统费用并且节省了电路板空间。16位的定点DSP核心的C24x设备为模拟设计者提供了一个数字的解决办法。这种方法不会牺牲 他们体统的精确度和处理能力。事实

54、上,系统的处理能力可以通过使用技术的高级控制算法被提高例如 自适应控制,过滤的滤波器和状态控制。 C24x DSP控制器提供可靠性和可编程序性。模拟控制系统,在另一方面,由于老化,组件耐受性减弱和偏差,被硬连线解决并且可能体验性能退化。高速中央处理单元(CPU)在实时允许数字式设计师处理算法而不是与查寻表的结果近似。合并信号 处理指示和通用控制功能,加上广泛的发展支持可利用为C24x设备的这些指令组 DSP控制器,减少了研制时间并且提供和传统8和16位一样的微型控制器的易用性。当通用TMS320定点DSPs从其他地方移动时,指令组也允许您保留您的软件投资。它是和C2xx其他成员一代的源码和目标

55、代码兼容的。源代码和C2x 一代兼容,向上的源码和德州仪器的C5x 一代的DSPs兼容。 C24x体系结构也非常适合程序控制信号。它与32位记数器一起使用,16位词长为存放中间结果,并且有两个有效的硬件移动装置来独立的衡量CPU中的数值。这个组合使量子化和截断错误减到最小,并且为另外的作用增加处理能力。这种功能也许包括可能取消在系统或估计技术的机械共鸣或者可能消灭在系统的状态传感器的陷波滤波器。C24x DSP控制器采用已经设置好的外围设备的功能的有点。这种功能允许德州仪器为不同价格/性能点或应用程序优化迅速配置各种各样的系列成员。-定时器-串行通信端(SCI, SPI)-模数转换器(ADC)

56、-事件处理器-系统保护,例如低压侦查和监视时钟DSP控制器周边图书馆在不断地成长和改变以适合今后嵌入控制市场的需要。TMS320F/C240是在DSP控制器 24x系列下引进的第一个标准设备。它规定一个单片数字式马达 控制器的标准。240可能执行20 MIPS。几乎所有指示在一个周期被执行的50 ns。这种高性能允许非常复杂的控制算法的实时施行,例如自适应控制和卡尔曼滤波器。高采样率可能也被用于使圈延迟减到最小。240有为高速信号处理和数字控制功能的体系结构而且它有为电动机控制应用提供一种单片解答 的外围设备。 240使用达到一个低功率散逸规定值的亚显微CMOS技术制作。并且包含了几个更好地存

57、储电量的 节电方式。一些受益于先进的处理能力的240的应用程序包括:-工业马达驱动-电力变换器和控制器-自动移动系统,例如电子动力方向盘、防锁死刹车和气候控制-装置和HVAC吹风机或者压缩机电动机控制-打印机、影印机和其他办公用品-磁带驱动器、磁性光驱和其他大容量存储器产品-机器人学和CNC铳床要功能作为系统的主导,DSP必须有健壮在芯片输入/输出和其他外围设备。240的事件处理器与在DSP上的任何一个有效的处理器都不一样。这个应用优化外部设备结合高性能DSP核心,使所有马达类型高精密度和高效率充分的易变速度控制的高级控制技术能够被使用。事件处理器包括特别脉冲宽度模块化(PWM)世代作用,例如一个可编程序的死带作用和提供在功率晶体管开关的科技目前进步水 平最大效率三阶段马达的一个空间向量PWM系统。三个独立的定时器,每一个都具有自己的计数器,支持各代的不对称的(没有中心的)以及对称的(被集中的)PWM信号波形。
