本发明提供了一种具有不等气隙马鞍磁极结构的再制造电机及制造方法。通过去除转子的部分鼠笼，使得鼠笼截面积减小，鼠笼绕组电阻得到提高，从而使得改造后的感应电机相比原感应电机能够产生更高的起动转矩，而在去除转子的部分鼠笼所释放出的转子空间内装入永磁体，可以使电机在运行时能够产生足够的气隙磁场能量，以及通过去除转子的部分外周面，使转子成为不等气隙结构，降低电机反电势谐波含量及齿槽转矩，以满足电机运行需要。且相比于新永磁同步电机，本设计是基于旧电机的升级再制造，价格相对新电机较低，与现有的电机再制造相比，本发明不需要匹配变频器启动，也不会出现永磁体脱落现象，且结构更加稳定。

The invention provides a remanufacturing motor with magnetic pole structure of saddle with unequal air gap and a manufacturing method thereof. By removing part of the squirrel cage of the rotor, the cross-section area of the squirrel cage is reduced, and the resistance of the squirrel cage winding is improved, so that the modified induction motor can generate higher starting torque than the original induction motor. Moreover, permanent magnets are installed in the rotor space released by removing part of the squirrel cage of the rotor, so that the motor can generate enough air gap magnetic field energy during operation. And by removing part of the outer surface of the rotor, the rotor becomes an unequal air gap structure, reducing the harmonic content of the motor back potential and the groove torque, so as to meet the needs of the motor operation. Compared with the new permanent magnet synchronous motor, the design is based on the upgrade and remanufacturing of the old motor, and the price is lower than that of the new motor. Compared with the existing motor remanufacturing, the invention does not need to match the frequency converter to start, and the permanent magnet will not fall off, and the structure is more stable.
