Analysis of electromagnetic force and vibration characteristics for transverse flux permanent magnet motor

Electromagnetic noise of motor is determined by the electromagnetic force acting on stator system and motor vibration characteristics. In this article, three dimensional model of motor is established, air-gap field is calculated by finite element method, and the compositions of stator system electromagnetic force and vibration characteristics of motor are analyzed. Electromagnetic noise sources are found out by analyzing the calculation results, which provides theoretic support for suppressing electromagnetic noise for transverse flux permanent magnet motor.
