无刷直流电动机转矩系数的研究

Study of Torque Constant in Brushless DC Motor

实例表明 ,在 BL DCM中转矩系数等于电势系数的关系 ,实际上不成立 ,至少是不确切的。文中分析了BL DCM中的机电能量转换过程 。

Based on example,this paper indicates that torque constant k t and back-EMF constant k e are not identical in BLDCM, at least can be said their relationship used to think is inexact. And then analyses the process of electromechanical energy conversion in BLDCM and brings out the reason why k t and k e are not identical and the factors making them different.
