摘　　要：为了实现在电机静止时能够提供不同的发热功率用于给电动汽车动力电池或乘员舱加热,对电机静止时实现电机主动发热的控制方式进行分析,并根据此控制方式在电机允许电流限值条件下,通过两种不同的方法分析计算电机静止发热功率的能力,计算出了在最大电流限制条件下电机在静止时发热功率能力与电机位置之间的关系,以及电机静止时主动发热能力与d轴电流之间的计算公式。最后,通过多组仿真及数据处理分析,验证了电机静止时主动发热能力与位置之间的关系与理论分析一致,以及在电机静止且d轴电流为定值时的电机发热功率与转子位置无关。分析结果能够用于根据电机转子位置最大利用电机发热功率、规范电机静止主动发热能力的验证测试以及电机静止发热时的控制标定。In order to provide sufficient heating power to the power battery or the vehicle crew compartment when the motor standstill,this paper analyzed the motor control method to implement this function.With this motor heating control method under motor allowed max current limitation,the motor heating ability were analyzed through two different ways.This paper calculated the relationship between the motor max heating ability and motor rotor position when motor standstill under allowed max motor current,and the relationship between motor heating power and d axis current when motor standstill.Finally,the analyzed conclusion were verified through multiple set of simulation and result data process.The conclusion of this paper can control the motor to provide max heating power according to the max heating ability of different rotor position,and can standardize the motor heating power ability testing method,and guide the motor control and calibration for motor heating when standstill.
