Abstract

The utility model provides a dual-claw polar multi-phase excitation generator belonging to the field of automobile electric apparatus. The dual-claw polar multi-phase excitation generator is mainly characterized in that armature windings are n-phase identical armature windings; each phase of the n phases spans n poles on a stator core respectively and is embedded with wires in sequnce; the phase difference of the armature windings is 360 / n degree, wherein n is an integer more than or equal to 4; and every two adjacent claw poles on each flange correspond to every n poles on a stator core. The dual-claw polar multi-phase excitation generator has the advantages that a rectifier has little heating quantity, long service life, simple and reliable voltage stabilizing and low cost, the generator is claw pole shaped, can be machined simply, can be magnetized uniformly, has high utilization degree, low whole-machine cost, and the like.

Description

technical field

[0001] The invention provides a double-claw pole type multi-phase excitation generator, which belongs to the field of automobile electric appliances. Background technique

[0002] As a pillar industry in our country, the automobile industry is playing an increasingly important role in the social economy. The generator is an important electrical appliance in the car, and has formed a large research field and industry. With the improvement of people's requirements for car comfort, the power of car generators is also increasing. The current generators of mid-to-high-end cars are generally around 1KW.

[0003] With the increase of generator power, the number of phases of its stator winding transitions from single-phase (about 150W), two-phase (about 450W) to three-phase (about 900W) commonly used now, but when the generator power reaches about 1KW , There will be problems such as too large voltage fluctuation, enhanced armature reaction, reduced efficiency, inc...
