Multi-mass-state permanent magnet motor system

Abstract

The utility model relates to the technical field of motors, and provides a multi-mass-state permanent magnet motor system, which comprises a first permanent magnet arranged on a first shaft, a first stator correspondingly arranged on the first shaft, a second permanent magnet arranged on a second shaft from inside to outside, a third permanent magnet arranged on the second shaft, a second stator correspondingly arranged on the second shaft, a fourth permanent magnet arranged on the vertical wall of the second shaft, a fourth stator correspondingly arranged on the vertical wall of the second shaft, a magnetic disk and a magnetic sleeve arranged at the front end of the first shaft, the stator and the rotor form a multi-germplasm electromagnetic coupling and decoupling relation, the output capacity of multiple electrical ports and multiple mechanical ports, high efficiency, wide interval and multi-fault-tolerant redundancy are reflected, and a solution for selectable multi-mechanical port output and diversified operation and control modes is provided for meeting the application requirement for complex change of load side working conditions.
