Multi-winding laminated claw-pole motor

Abstract

The invention relates to a multi-winding laminated claw pole motor, which is mainly used for permanent magnet synchronous motor. A coil (1) is wound on a framework (2); a plurality of groups of laminated claw poles (3) are respectively arranged in the framework (2) from two ends; the two groups of laminated end plates (4) are respectively arranged at two ends of the framework (2) to form a single-winding combination (5), the laminated claw poles (3) and the laminated end plates (4) are formed by laminating a plurality of silicon steel sheets, and the motor stator can be formed by coaxially arranging two or three single-winding combinations (5) side by side and staggered at an electromagnetic angle of 90 degrees or 120 degrees in the circumferential direction. Compared with most existing motors, the motor winding processing technology is simplified, the reliability is improved, the copper consumption is reduced, compared with an existing asynchronous motor, the efficiency and the powerfactor are greatly improved, compared with an existing permanent magnet synchronous motor, the rotor structure is simplified, the cost is reduced, the self-starting capacity is good, and a high-powermotor can be manufactured.

Description

[0001] Technical field [0002] The invention relates to a multi-winding lamination claw pole motor, which is mainly used in a permanent magnet synchronous motor and belongs to the technical field of motor manufacturing. Background technique [0003] Most of the existing motors are asynchronous motors, which have the characteristics of simple manufacture and low price, but they also have the disadvantages of low efficiency and power factor. The existing ordinary permanent magnet synchronous motors are superior to asynchronous motors in terms of efficiency and power factor. Electric motors, however, do not have self-starting capabilities. Generally, an asynchronous starting device needs to be added to the rotor to form a working condition of asynchronous starting and synchronous operation, which increases the process difficulty and cost of motor manufacturing. In addition, whether it is an asynchronous motor or an ordinary permanent magnet synchronous motor, the manufacturing p...

Problems solved by technology

[0003] Most of the existing motors are asynchronous motors, which have the characteristics of simple manufacture and low price, but also have the disadvantages of low efficiency and power factor. The existing ordinary permanent magnet synchronous motors are superior to asynchronous motors in terms of efficiency and power factor. Motors, but do not have self-starting capability, generally need to add an asynchronous starting device on the rotor to form a working condition of asynchronous starting and synchronous operation, which increases the process difficulty and cost of motor manufacturing

In addition, whether it is an asynchronous motor or an ordinary permanent magnet synchronous motor, the winding manufacturing process is time-consuming, laborious, low utilization rate of wires, low dielectric strength, and poor reliability. Motor manufacturers have deep feelings

Claw pole motors can solve the difficulty of motor winding processing, but the existing permanent magnet claw pole synchronous motors cannot pass through large alternating magnetic flux because the claw poles are integrally manufactured, so the power is not large, generally very Hard to exceed 10 watts
