Co-Simulation of High Speed Claw Pole Motor with Outer Rotor Based on Simplorer

doi:10.11985/2015.09.008

Abstract

Abstract:

The special structure and operating principle of the high speed claw pole motor with axially segmented outer rotor was presented in this paper. In order to obtain an accurate simulate result, a three dimension （3D） finite element model （FEM） that was consistent with actual parameters was built in Maxwell 3D due to its asymmetry of the magnetic circuit. Considering the coupling effect of the motor finite element model and control circuit model in calculation, a control system model adopting sensorless and double-loop control strategy was done in a co-simulation platform using Maxwell&Simplorer software. Inverter circuit and commutation circuit were included in the control circuit to achieve the target of driving motor. From the simulation result, the motor ran stably and had a good starting performance. Research in this paper has reference value for control system design and optimization of high speed claw pole motor with axially segmented outer rotor in some degree.
