摘要
本文推导了永磁无刷直流电机电感计算公式 ,并在此基础上引入平均电流和电磁转矩的修正系数 ,以计入电感的影响 ,同时也考虑波形不匹配对电流和电磁转矩的影响 。
Inductance of permanent magnet brushless DC motor is disussed.Further,rectify the value of mean current and magnet torque with a coefficient in order to allow for the influence of inductance,which depends on rotate speed and inductance.Also the matching between input voltage and counter EMF is taken into account.Therefore the method is more precise than usual one.
