Two-channel symmetric output permanent magnetic generator

Abstract

The invention relates to a two-channel symmetric output permanent magnetic generator. The number of poles of a stator is 14, the number of slots is 21, the pole slot ratio is 2:3, the pitch y=1, a stator core is not in a chute state, two sets of windings are independently wound on the core, each set of windings contain three windings, and a connection mode is a star-shaped connection mode. The two-channel symmetric output permanent magnetic generator is advantaged in that magnetic lines corresponding formed by the two sets of windings are good in consistency, parameters of the two sets of windings are consistent, the formed armature reaction is consistent, isolation is realized through vacant slots, so the two sets of windings can output completely identical performance, the output symmetry of two channels of the generator is good, the counterelectromotive force sine property is good, symmetric output of the two channels can be realized, when one set of windings is burnt out, influenceon the other set of windings can be avoided, and relatively good work performance and stability are realized.

Description

technical field [0001] The invention belongs to the field of electromagnetic power generation and relates to a generator, in particular to a dual-channel symmetrical output permanent magnet generator. Background technique [0002] In the currently used double-winding fault-tolerant generator, the two sets of windings are evenly distributed on the entire iron core, and the two sets of windings are in physical space. There is cross-linking in the space magnetic field, and the output performance of the two sets of windings has mutual influence. At the same time, after one set of windings is burned due to short circuit, another set of windings will be burned, and the performance and working stability are poor.
