Description

Stator of claw-pole motor

Technical Field

The utility model relates to the technical field of electric machines, especially, relate to a stator of claw utmost point motor.

Background

The existing claw-pole motor stator has four structures: the first structure is that the stator and the ordinary stator adopt a slotted structure to provide an excitation magnetic field, and the rotor adopts a claw pole structure. The second structure adopts an outer rotor structure, and the stator adopts a claw pole structure; and a cylindrical structure is added on the claw pole structure and used for winding. The third structure is that the stator adopts a claw pole structure, the rotor adopts an inner rotor permanent magnet structure, and the stator is formed by laser welding an upper claw pole, a lower claw pole and an outer iron block together. The fourth stator and the rotor are all formed by claw pole structures.

However, the existing four stator structures have the following disadvantages: the stator structure of the first claw-pole motor is complex in structure and inconvenient to wind, and the using amount of copper is greatly increased, so that the cost is increased. The second structure has a much reduced amount of copper compared to the first structure, but its copper is directly wound on the iron cylinder, so that its loss increase efficiency is reduced. The third configuration has an increased amount of copper relative to the second configuration, but its losses are not as great as the second configuration. However, the wall of the claw pole of the copper wire is not smooth like a cylinder when the copper wire is wound, so that the copper wire is easy to damage when the copper wire is wound, the process difficulty is increased in manufacturing, and the cost is increased relatively to the second type. The stator and the rotor of the fourth structure adopt claw pole structures, so that the using amount of copper is greatly increased, and the manufacturing cost is increased.
