The stator assembly including stator windings is fixed on the stator seat of generator assembly. Pairs of permanent magnet embedded on outer ring of rotor body of the rotor assembly are fixed on the rotation body of the generator assembly. It is homocentric between bore of stator body of stator assembly and rotation center of rotor body of rotor assembly. The invention can prevent rare earth permanent magnets from falling off in rotation, and guarantee enough intensity of magnet yoke on outside of rare earth permanent magnets. Structure with no bearing adopted in the invention makes rotor simple and compact and miniaturization so as to save cost. Features are: high output efficiency, and high output power, raised heat dispersion, reduced weight, and increased reliability, and service life.
Description
technical field [0001] The invention relates to a multi-pole inner rotor type permanent magnet generator, which is particularly suitable for miniaturized and light-weight medium and high-power generator sets, and belongs to the technical field of generators. Background technique [0002] At present, in the prior art, the permanent magnet generator is mainly composed of a stator assembly and a rotor assembly. Rare earth permanent magnets are usually used in motors or low-power generators, or in low-power starter / generator dual-purpose motors, and when rare earth permanent magnets are used in generators, most of them are of the outer rotor type. For example, the patent No. CN01112432.6 discloses a permanent magnet rotating motor that can simply, reliably and firmly fix the permanent magnet in the magnet insertion hole of the outer rotor; and when the permanent magnet is used in the inner rotor motor, it is generally used on the rotor surface Sintered permanent magnets, as dis...
