Design and Performance Analysis of Brushless DC Motor Using ANSYS Maxwell

Brushless Direct Current (BLDC) motors having the advantages of better speed versus torque characteristics, high dynamic response, high efficiency, long operating life, noiseless operation, higher speed ranges, are superior to brushed DC motors and induction motors. This paper describes the method of designing BLDC motor with detailed design equations. Motor geometry is built in RMxprt software tool of ANSYS Maxwell. The analytical design is then implemented in Maxwell 2D for further analysis. Simulation results accomplishing performance characteristics are included. The designed motor exhibits an efficiency of 87% and is able to meet the designed value of torque.
