Single-line multi-pole outer rotor three-phase generator

Abstract

The invention relates to a generator, in particular to a single-line multi-pole outer rotor three-phase generator. The generator comprises a shell, wherein a stator is arranged in the shell; a plurality of permanent magnetic steels are arranged on the inner wall of the shell; the polarity of the same ends of two adjacent permanent magnetic steels is opposite; the stator is formed by mutual superposition of a plurality of silicon steel sheets; a plurality of wire slots are radially arranged on the stator; and generator windings are arranged in the wire slots. The generator is characterized in that the wire slots are radially and uniformly distributed on the outer edge of the stator; the outer ends of the wire slots are communicated with the outer edge of the stator; the number of the wire slots is integral multiple of 3; the generator windings comprise enamelled wires a, enamelled wires b and enamelled wires c; the three kinds of enamelled wires are respectively put at the bottoms of three wire slots 1, 2, 3 and are wound continuously in the wire slot order of 1-1, 2-2 and 3-3; and after being wound, the enamelled wires a, b and c serve as the three-phase output ends of the generator. The single-line multi-pole outer rotor three-phase generator has low manufacturing cost and light weight.

Description

[0001] technical field [0002] The invention relates to a generator. Specifically, it is a stator winding on a single-wire multi-pole outer rotor three-phase generator. Applicable to external rotor generators. Background technique [0003] It is known in the generator manufacturing industry that most of the existing small generators are internal rotor generators. The generator winding of this inner rotor generator consists of multi-turn coils, which are embedded on the inner wall of the casing. Because the power generation winding of this inner rotor generator is composed of multi-turn coils, not only requires more enameled wires, consumes more copper materials, and has high manufacturing costs, but also the weight of the generator is relatively heavy. Taking a 10KW generator as an example, its weight Up to 300Kg. Contents of the invention [0004] The problem to be solved by the present invention is to provide a single-wire multi-pole external rotor three-phase gener...
