摘要:

为计算转子54槽六相双层叠绕组端部漏感,采用镜像法搭建了转子端部漏感的计算模型,推导出了转子端部漏感参数计算公式,并给出了相应的计算结果。并以一台64 kW无刷双馈电机为原型机,搭建了试验平台。原型机试验结果验证了电机漏感参数计算的正确性。

Abstract:

In order to calculate leakage inductance of rotor end of 54 slots six-phase double coils,the calculation model of the leakage inductance of rotor end was set up by the mirror method, the formula for calculating the leakage inductance of rotor end was derived,and the corresponding calculation results were given.An experiment platform with a 64 kW brushless doubly-fed motor as the prototype was built. Experimental results verify the correctness of magnetic field energy method for calculation of slot leakage inductance parameters.

Key words: parameter of the leakage inductance, brushless doubly-fed machine (BDFM), mirror method, calculation model, equivalent circuit
