Claw pole type generator

Abstract

The invention discloses a claw pole type generator which comprises a stator core (1), a stator winding (2), a rotor, a front claw pole (4), a rear claw pole (5), a rotating shaft (6), a rotor winding (7) and a communication cavity (8), the front claw pole comprises a first disc body (41) and a plurality of first claw parts (42), the rear claw pole comprises a second disc body (51) and a plurality of second claw parts (52), and the claw pole type generator is characterized in that 48N winding grooves are uniformly distributed in the circumferential direction, the number of the front claw poles and the number of the rear claw poles are 8N, the stator winding is composed of three phases of windings, each phase of winding is composed of eight coils, the span of each coil is 3, in other words, one coil edge of the stator winding is placed in the first winding groove, and the other coil edge of the stator winding is placed in the fourth winding groove. According to the invention, inter-pole magnetic leakage can be reduced, air-gap flux density is increased, output power of the generator is increased, and heat dissipation effect of the generator is improved.

Description

Technical field [0001] The present invention relates to the technical field of claw pole generator, specifically to a claw pole generator, specifically an 8 pair pole 48 slot claw pole generator. Background [0002] Claw-pole generator is a mechanical and electrical equipment that converts mechanical energy into electrical energy, and is widely used in the automotive industry and construction machinery industry with internal combustion diesel engines. The traditional claw pole generator excitation adjustment is convenient, but its inter-pole leakage is large, resulting in large excitation current, high excitation loss, low power density, so that the motor power is small, the heat dissipation effect is general, limiting its application field / range. Contents of the Invention [0003] Object of the present invention is to overcome the deficiencies in the prior art, to provide a claw-type generator, which through the winding slot, front claw pole, rear claw pole number design and ...
