Problems solved by technology

[0003] The permanent magnet rotor used in the generator generally adopts the outer rotor type, and can only be made into a low-power generator. When the permanent magnet rotor is used in the inner rotor of the motor, most of them have a rotating shaft and a bearing support method. This structure is difficult to make to miniaturization, weight reduction and thinning

Abstract

The disclosed rotor of permanent magnet generator is suitable to permanent magnet generator in miniaturization, lightweight, and thin type. The rotor includes punched pieces of rotor, permanent magnets. Characters are that riveting punched pieces of rotor constitutes rotor body where slots for taking in permanent magnets are distributed around circumferencial direction. After taking in permanent magnets, rotor body is fixed on rotary body of generator directly. Structure with no bearing adopted in the invention makes rotor simple and compact farthest so as to save cost, raise service life, realize high output efficiency, and high output power. The invention guarantees that when rotor rotates, rare earth permanent magnet will not fall off, as well as reduces magnetic leakage, raises safety, stability and durability of rotor.

Description

technical field [0001] The invention relates to a rotor of a multi-pole inner rotor type permanent magnet generator, in particular to a rotor which improves structural safety and power generation efficiency, and is suitable for miniaturized, lightweight and thin permanent magnet generators , belongs to the technical field of generators. Background technique [0002] Before the disclosure of the present invention, in the known technology, there are many disclosures about the application of permanent magnet rotors in electric motors. For example, the application number is CN03818684.5, which discloses a rotating electrical machine comprising a stator with multiple coils and The inner side of the stator, the rotor core rotatably supported on the rotating shaft, and a plurality of magnets accommodated in slot holes provided in the rotor core, the circumferential direction of the plurality of magnets constituting one magnetic pole The angle is represented by an electrical angle,...
