Problems solved by technology
After the permanent magnet synchronous generator is made, the air gap magnetic field cannot be adjusted, and the temperature coefficient of the permanent magnet material is relatively large, which will cause fluctuations in the output voltage of the generator when the load changes or the ambient temperature changes, affecting the normal operation of the load.

Description
technical field [0001] The invention belongs to the field of self-starting permanent magnet motors, in particular to a starting permanent magnet motor with different numbers of poles. Background technique [0002] In industrial production, agricultural production or daily life, motors are widely used. The use of motors involves almost every aspect of our lives. Different fields have different requirements for motor performance, but they all need to save energy and increase the output of motors. capacity, output torque. [0003] Asynchronous motors are used in all aspects of life with simple structure, low manufacturing cost, high operational reliability, and large output torque. In recent years, permanent magnet motors have high torque density, small speed fluctuations, and are easy to use It is gradually replacing asynchronous motors due to the characteristics of parallel operation of platforms. At the same time, because the motor will be resisted when it is self-starting,...
