Large inertia motor and implementation method thereof

The invention discloses a large inertia motor and an implementation method thereof. The large inertia motor comprises a permanent magnet servo motor, wherein the permanent magnet servo motor is equipped with a split encoder. The large inertia motor further comprises an inertia disc, wherein the inertia disc is matched and connected with a reflective grating assembly of the split encoder. The implementation method comprises the step of directly connecting the inertia disc and the reflective grating assembly on the permanent magnet servo motor into a whole. The axial length of the motor will notbe lengthened while the inertia of the motor is increased, and installation requirements can be ensured. In addition, a motor casing, a shaft, stator and rotor cores and the like are enabled to sharesmall-inertia motor parts, thereby greatly saving the cost. 本发明公开了种大惯量电机及其实现方法，大惯量电机包括永磁伺服电机，所述永磁伺服电机上设有分体编码器，所述大惯量电机还包括惯量盘，所述惯量盘与分体编码器的反射式光栅组件配合连接，实现方法为：将惯量盘直接与永磁伺服电机上的反射式光栅组件连接为体。本发明在加大电机惯量的同时，电机轴向长度不会加长，能保证安装需求，并且使得电机机壳、轴、
