Magnetic Flux Modelling and Analysis of 120 kW Brushless DC Motor for Medium Bus Application Based with JMAG

In this paper, magnetic flux (distribution and direction) modelling and analysis of brushless DC (BLDC) motor that output power is 120 kW using JMAG software is investigated. Before performing magnetic flux analysis, the motor parameters is verified by using JMAG-Express. After verifying the design, the magnetic flux distribution and direction is analyzed. The purposed of this research is investigating the operation area of magnetization-demagnetization process in the stator and rotor core of BLDC motor.
