直流无刷电机的在使用上怎么区分类型?

1、可调速驱动机械
1. Speed-adjustable driving machinery
速度需求恣意设定和调理,但控制精度请求不高的调速系统。这类系统分为两种:一种是开环调速系统,另一种是闭环调速系统(此时的速度反应器件多采用低分辨率的脉冲编码器或交、直流测速等)。通常运用的电机主要有三种:直流有刷电机、直流无刷电机和异步电机。这在包装机械、食品机械、印刷机械、物料保送机械、纺织机械和交通车辆中有大量应用。
Speed requirement is arbitrarily set and adjusted, but the control precision is not high. This kind of system can be divided into two kinds: one is open-loop speed control system, the other is closed-loop speed control system (at this time, the speed reactor mostly uses low-resolution pulse encoder or AC, DC speed measurement, etc.). There are three kinds of motors commonly used: DC brush motor, DC brushless motor and asynchronous motor. This is widely used in packaging machinery, food machinery, printing machinery, material delivery machinery, textile machinery and transportation vehicles.
可调速系统应用范畴一开端用的较多的是直流电机,随着交流调速技术特别是电力电子技术和控制器的开展,交流变频技术取得了普遍的应用,变频器和交流电机浸透到原来直流调速系统应用的绝大多数范畴。近几年来,由于无刷直流电机体积小、重量轻和高效节能等优点的日益突出,中小功率交流变频系统正逐步被无刷直流调速系统所取代,特别是在纺织机械、印刷机械等原来变频系统应用较多的范畴。而在一些直接由蓄电池供电的应用范畴,如今更多的运用直流无刷电动机。
At the beginning, DC motor is widely used in the field of application of adjustable speed system. With the development of AC speed control technology, especially power electronics technology and controller, AC frequency conversion technology has been widely used. Frequency converter and AC motor soak into the vast majority of the original application of DC speed control system. In recent years, due to the increasingly prominent advantages of BLDCM, such as small size, light weight, high efficiency and energy saving, small and medium power AC frequency conversion system is gradually replaced by BLDCM speed regulation system, especially in textile machinery, printing machinery and other original frequency conversion systems. In some applications directly powered by batteries, more and more brushless DC motors are used nowadays.
2、定速驱动机械
2. Constant Speed Driving Machinery
普通工业场所不需求调速的范畴常常大多数采用三相或单相交流异步和同步电机,随着电力电子技术的进步,在功率不大于10kw且连续运转的状况下,为了减小体积,俭省资料,进步效率和降低损耗,越来越多的电机正被无刷直流电机所取代,这类应用有:自动门、电梯、水泵、风机等。而在功率较大的场所,由于一次本钱和投资较大,除了永磁电机以外还需求增加驱动器等设备,因而目前较少应用无刷电机。

Three-phase or single-phase AC asynchronous and synchronous motors are often used in general industrial areas without speed regulation. With the development of power electronics technology, more and more motors are being brushless straightening in order to reduce volume, save data, improve efficiency and reduce losses under the condition of power less than 10 kW and continuous operation. Flow motors are replaced by automatic doors, elevators, pumps, fans and so on. In places with high power, brushless motors are seldom used at present because of large primary cost and investment, besides permanent magnet motors, there is also a need for additional devices such as drivers.
3、精细控制
3. Fine Control
伺服电动机在工业自动化范畴的高精度控制中不断扮演者非常重要的角色,应用场所不同,对伺服电动机的控制性能请求也不尽相同,在实践的应用中,伺服电动机的各种不同的控制方式:转矩控制/电流控制、速度控制、位置控制。无刷直流电机由于良好的控制性能,在高速、高精度定位系统中逐渐的取代可直流电机和步进电机,成为现代伺服系统选择的电机之一。目前,扫描仪、摄影机、CD光驱驱动、医疗诊断CT、计算机硬盘驱动和数控车床驱动中等都普遍的采用了无刷直流电机伺服系统用于精细控制。
Servo motors play a very important role in high-precision control of industrial automation. The requirements for control performance of servo motors vary with different application places. In practice, different control modes of servo motors include torque control/current control, speed control and position control. Control. Because of its good control performance, brushless DC motor gradually replaces DC motor and stepper motor in high-speed and high-precision positioning system, and becomes one of the motors selected by modern servo system. At present, brushless DC motor servo system is widely used for fine control in scanner, camera, CD drive, medical diagnostic CT, computer hard disk drive and CNC lathe drive.
4、其他应用
4. Other Applications
家用电器如自动洗衣机,CD唱机等;军事应用如潜艇,军舰上;还有大型同步电机的启动等。
Household appliances such as automatic washing machine, CD player, etc., military applications such as submarines, warships, and the start of large synchronous motors.
