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

Abstract

The invention relates to a generator, in particular to a single-line multi-pole outer rotor single-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 6; the generator windings comprise enamelled wires a, enamelled wires b and enamelled wires c; the enamelled wires a, b and c are respectively put at the bottoms of three wire slots 1, 2, 3 and are wound continuously in the wire slot order of 1-6-1-6, 2-5-2-5 and 3-4-3-4; and after being wound, the enamelled wires a, b and c are connected as one in a cross manner to serve as the output end of the single-phase generator. As fewer enamelled wires and fewer copper materials are consumed for the stator windings, not only is the manufacturing cost of the generator low but also the weight of the generator can be greatly reduced.

Description

technical field [0001] The invention relates to a generator. Specifically, it is a small single-wire multi-pole external rotor single-phase generator. Background technique [0002] It is known in the generator production industry that most of the existing small generators are internal rotor generators. The inner rotor of this kind of inner rotor generator is driven by power, the rotating shaft is excited to generate a magnetic field, or the rotating shaft is equipped with permanent magnets, and the generating winding is embedded on the inner wall of the casing. The generator winding is composed of multi-turn coils. 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 [0003]...
