I摘 要通常情况下如果不进行特殊处理，当关掉三相异步电动机电源的同时，从理论上讲，其不能立刻停止运动，这是由于旋转过程中存在惯性，基于机械工艺的视角来看，这种现象决不能出现，比如在镗、铣、钻等各式各样的机床上，不管从精准定位上考虑，还是生产效率等来看，都需要电机能够相对瞬时停车，这就需要针对具体情况引入相应的制动装置或者制动方法，通常情况下所谓的制动方法可以概括为两类：即电气方式与机械方式制动，引入一定的与原电机转向相反的力矩，进行阻碍电机继续运转，该方式称为电气方式制动；再有就是引入相关的机械装置致使电机产生刹车的功效，也就是所谓的机械方式制动。本文主要针对于能耗制动强制使三相异步电动机进行刹车展开了一系列的研究，在论文中对三相异步电动机制动方案进行了有效比较，并针对于能耗制动控制系统搭建起实验平台，并在实验台实现了三相异步电动机的迅速停机。关键词：三相异步电动机；能耗制动；迅速停机IIAbstractUnder normal circumstances, if special processing is not performed, when the power of the three-phase asynchronous motor is turned off, theoretically, it cannot stop the motion immediately. This is due to the inertia in the rotation process, based on the viewpoint of the mechanical process. Phenomenon must not occur. For example, in various types of machine tools such as boring, milling, drilling, etc., regardless of precision positioning or production efficiency, the motor needs to be able to stop relatively instantaneously, which needs to be introduced for specific situations. Corresponding braking devices or braking methods, in general, the so-called braking methods can be summarized into two categories: electrical and mechanical braking, introducing a certain torque opposite to the original motor steering, to prevent the motor from continuing to operate, This method is called electric mode braking; then there is the introduction of the relevant mechanical device to cause the motor to produce braking effect, which is c...
