摘　　要：本文阐述了等效法测量电机温升的原理,提出了一种热态电阻的计算方法,利用金属电阻与温度变化的线性关系从而得到电机绕组温升,并与热电偶法温升测试结果进行比较,验证该计算方法的正确性。The paper expounds the principle of the method of equal effect to measure motor temperature rise. It puts forward a calculation method of heating resistance. Taking advantage of the linearity relationship between metal resistance and temperature changes, the motor winding temperature rise is obtained. Finally, compared with the temperature rise test results by using thermocouple method, it verifies the accuracy of this approach.
