Abstract
Transient magnetic field simulation analysis can provide reference for the research and design of the motor body.A small permanent magnet brushless DC motor was analyzed and designed.Based on theoretical formulas,the dimensions of the stator and rotor,stator slot shape,winding,etc.of the brushless DC motor were calculated.The Maxwell finite element simulation software was used to simulate and analyze the magnetic field distribution of the motor core,no-load back force,torque,motor starting,and other aspects of the design scheme.A design scheme that meets the requirements was obtained.
