Abstract

An external-rotor intermediate-frequency permanent magnet generator device comprises a power interface fixing disc, a power shaft arranged on the power interface fixing disc, an internal stator connected with the power interface fixing disc, an annular external rotor connected with the power shaft and having a magnetic steel, and a protection cover connected with the internal stator and provided with an air inlet. The external rotor of the intermediate-frequency permanent magnet generator device is arranged outside the internal stator; an iron core lamination of the stator is designed to a coil slot shape and is distributed on the external circumference; the winding form is designed to a centralized winding form; and a stator winding coil is wound on the teeth individually in such a manner that one tooth corresponds to one independent coil and both sides of each coil have one pole respectively so as to form a fractional-slot winding. The stator iron core can be conveniently fixed on a stator reinforcement rib because the coil has a short and small end; the rotor is a multi-polar magnetic steel rotor; and the stator and the stator iron core are shorter in comparison with the generator of the same capacity, so that generator can be designed to a flat structure, which can have no rear bearing and of which the front end can be directly connected with an interface of a power oil machine.

Description

technical field [0001] The invention relates to the field of a charging generator for an uninterruptible power supply of a communication station, and more specifically refers to an outer rotor type intermediate frequency permanent magnet generator. Background technique [0002] With the rapid development of industrial and agricultural production and the improvement of people's living standards, the demand for electricity is increasing rapidly, especially the demand for uninterruptible power supplies in communication stations, and the contradiction between supply and demand is very prominent. [0003] At present, the uninterruptible power supply of the communication station is generally composed of a DC battery (lithium battery or other DC battery that can be used for a long time), a diesel or gasoline generator set, and an AC-DC charging system. However, the current products of diesel or gasoline generating sets are larger, heavier, and less efficient. Therefore a kind of p...
