摘要
本文详细分析了无刷直流电机制动过程及回馈能量产生的机理,给出了过压保护电路及泵升电容、泵升电阻的计算公式,此计算方法适用于解决无刷直流电机制动状态下电压过高的情况。
This paper analysize the braking state of BLDC and the feedback mechanism in detail,and give the over-voltage protection circuit and the formula of pumping capacity and pumping resistance.This calculation formula is suitable for solving the conditions of high voltage in BLDC's braking state.
