无刷直流电机的种类你知道几个?

来源:http://www.jnmcd.com 发布时间:2018-12-05 浏览:
因为无刷直流电机既具有沟通电机的结构简单、运转可靠、保护方便等一系列长处,又具有直流电机运转效率高、无励磁损耗以及调速功能好的特点,故在当今国民经济的各个范畴,如医疗器械、仪器仪表、化工、轻纺以及家用电器等方面的运用日益遍及。
Because brushless DC motor has a series of advantages such as simple structure, reliable operation, convenient protection and so on, as well as the characteristics of high efficiency, no excitation loss and good speed regulation function of DC motor, it is in various areas of the national economy, such as medical equipment, instruments, chemical industry, textile and home. The use of electrical appliances is increasingly widespread.
无刷直流电机的运用主要分为以下几类:
The application of brushless DC motor can be divided into the following categories:
1、可调速驱动机械
1. Speed-adjustable driving machinery
速度需要恣意设定和调节,但操控精度要求不高的调速体系。这类体系分为两种:一种是开环调速体系,另一种是闭环调速体系。
Speed needs to be set and adjusted arbitrarily, but the control accuracy is not high. This kind of system can be divided into two kinds: one is open-loop speed regulation system, the other is closed-loop speed regulation system.
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、物料输送机械、纺织机械和交通车辆中有大量运用。
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 conveying machinery, textile machinery and transportation vehicles.
可调速体系运用范畴一开始用的较多的是直流电机,跟着沟通调速技能特别是电力电子技能和操控器的开展,沟通变频技能获得了广泛的运用,变频器和沟通电机渗透到原来直流调速体系运用的绝大多数范畴。
In the beginning, DC motors were widely used in the application of speed control system. With the development of communication speed control skills, especially power electronics skills and controllers, communication frequency conversion skills were widely used. Inverters and communication motors penetrated into most of the original DC speed control systems.

近几年来,因为无刷直流电机体积小、重量轻和高效节能等长处的日益突出,中小功率沟通变频体系正逐渐被无刷直流调速体系所取代,特别是在纺织机械、印刷机械等原来变频体系运用较多的范畴。而在一些直接由蓄电池供电的运用范畴,现在更多的运用直流无刷电动机。
In recent years, due to the increasingly prominent advantages of BLDCM, such as small size, light weight, high efficiency and energy saving, the medium and small power communication frequency conversion system is gradually replaced by BLDCM speed regulation system, especially in the areas of textile machinery, printing machinery and other original frequency conversion system. In some applications directly powered by batteries, brushless DC motors are now more widely used.
2、定速驱动机械
2. Constant Speed Driving Machinery
一般工业场合不需要调速的范畴往往大多数选用三相或单相沟通异步和同步电机,跟着电力电子技能的进步,在功率不大于10kw且连续运转的情况下,为了减小体积,节约材料,提高效率和降低损耗,越来越多的电机正被无刷直流电机所取代。
In the general industrial occasions, asynchronous and synchronous motors with three-phase or single-phase communication are often used. With the improvement of power electronics skills, more and more motors are being brushless straightening in order to reduce volume, save materials, improve efficiency and reduce losses when the power is less than 10 kW and running continuously. Stream motors are replaced.
这类运用有:主动门、电梯、水泵、风机等。而在功率较大的场合,因为一次成本和投资较大,除了永磁电机以外还需要添加驱动器等设备,因此现在较少运用无刷电机。
This kind of application includes: active door, elevator, water pump, fan, etc. In the case of high power, brushless motors are seldom used because of the large cost and investment, besides permanent magnet motors, drivers and other devices are also needed.
