资料介绍

为了使无刷直流电机长期稳定运行,采用加保护电路的方法使其正常工作,保护电路主要由欠压保护、过流保护、短路保护等组成,在软件里设置电压、电流的阈值,直接对电压、电流进行检测并产生相应的保护,以免对电路和电机造成损害,并且做了相应的欠压、过压、过流测试实验。实践应用表明,该设计的几种方案切实可行,能够在异常情况下及时对电机做出保护动作。

To make the brushless DC motor worked stably for a long time,the method of adding a protective circuit was adopted.The protective circuit is mainly made up of the under-voltage protection,over-current protection and short-circuit protection,etc.The voltage and current threshold values were set in the software to detect the voltage and current directly and generate the appropriate protection to avoid damaging the circuit and motor.The appropriate testing experiments of under-voltage,overvoltage and overcurrent were made as well.A practical application shows that several schemes of the design are feasible and can protect the brushless motors in abnormal condition timely.
