Remanufacturing permanent magnet motor based on mixed permanent magnet and mixed laminated iron core

Abstract

The invention discloses a remanufacturing permanent magnet motor based on a mixed permanent magnet and a mixed laminated iron core. The remanufacturing permanent magnet motor comprises a mixed permanent magnet, a mixed laminated stator / rotor iron core, and an usable enclosure, end cover, shaft and the like in a waste motor. The mixed permanent magnet is segmentally arranged along an axial direction. At least one segment of the permanent magnet is a permanent magnet segment dismounted from the waste motor and is located in a middle or end part position of the mixed permanent magnet. According to the mixed laminated stator / rotor iron core, a stator / rotor iron core is segmentally arranged along the axial direction to be stator / rotor lamination segments of different materials, the mixed laminated stator / rotor iron core includes first stator / rotor lamination segments of iron-based amorphous alloy materials or remanufacturing silicon steel materials and second stator / rotor lamination segments of materials of recycled silicon steel dismounted from the waste motor; and the first stator / rotor lamination segments and the recycled permanent magnet segments are equal in length and are locatedin the same axial positions. The output torque of the remanufacturing permanent magnet motor is effectively improved, the loss is reduced, the motor performance is improved, and thus specific application of the remanufacturing permanent magnet motor is promoted.

Description

technical field [0001] The invention relates to a remanufactured permanent magnet motor, more specifically to a remanufactured permanent magnet motor in which precious components such as silicon steel cores and permanent magnets of the waste motor are reused in the remanufactured motor. Background technique [0002] Due to the short life cycle and low quality of some consumer products, the number of waste products has risen sharply. Countries have realized the importance of environmental issues and have successively proposed environmental governance methods and measures. However, traditional environmental governance methods are terminal. Governance cannot fundamentally solve the problem of environmental pollution. To completely solve environmental problems, we must start from the source. Specific to the manufacturing industry, it is necessary to consider the impact of the entire life cycle of the product on the environment, maximize the use of raw materials and energy, redu...

AI Technical Summary

Problems solved by technology

Because its saturation magnetic density is lower than that of silicon steel material, if the iron core is directly replaced with iron-based amorphous alloy material, although the loss of the motor is reduced, it will cause the torque contraction of the remanufactured motor

[0007] In fact, due to the above situation, the current manufacturing of permanent magnet motors is still in the stage of R&D and debugging.
