The Analysis of Stator System Natural Frequency Calculation Method on Transverse Flux Permanent Magnet Motor

The stator and armature coils of the transverse flux permanent magnet motor are perpendicular to each other in space. Its core size and coil size are independent of each other, size can be arbitrarily selected in a certain range. Thus the high torque density is suitable for some special occasions. First of all, the finite element build accurate stator system model. Secondly we calculated modal of the motor, according to the results of calculation analysis concluded that the stator system analytic calculation of the equivalent model. The above work has been the calculation formula of the stator system natural frequency that provide calculation basis for transverse flux motor vibration noise analysis.
