电感参数直接影响电机稳态和动态的运行性能。车用驱动电机的磁路饱和和交叉耦合效应严重，进一步增加了电感参数精确计算的难度。计算电感时若忽略饱和效应的影响，会导致转矩控制精度不足。结合车用电机负载电流范围大、磁路饱和变化复杂的特点，对比分析了视在电感和增量电感随负载电流增大的变化关系及两者之间变化的差异，进而研究了电机斜极对电感的影响。结果表明：在磁路高度饱和时，两种电感的计算结果差距较大，增量自感为视在自感的11%~30%；斜极会影响磁导率的分布，对电机自感参数影响很大，互感次之。

The steady-state and dynamic operating performances of the motor can be directly affected by inductance. The effects of magnetic circuit saturation and cross-coupling are more serious for the vehicle drive motor, so that the accurate calculation of the inductance parameters will be more difficult. Ignoring the saturation effect when calculating the inductance will reduce the torque control accuracy. At the same time, the load current range will become very large and the change of magnetic circuit saturation will be complicated in the vehicle drive motor. By comparing the apparent inductance and incremental inductance when the load current is increased, the relationship and change law between them are analyzed, and the influence of skewed rotor on the inductance is studied. The results show that large difference exists between the calculation results when the magnetic circuit is highly saturated, for which the incremental inductance is 11%~30% of the apparent inductance. The changes in permeability with skewed rotor have a great impact on the motor’s self-inductance parameters, followed by mutual inductance.
