Design of axial flux permanent magnet brushless DC motor for robot joint module

Abstract

Joint modules for robot system require actuators with high torque and slim topology for easy loading. Axial flux permanent magnet (AFPM) machine with high torque density is proposed and manufactured. Magnetic design is executed by numerical analysis and analytic model. Manufactured motor is tested and verified characteristics. Through the comparison with radial flux BLDC motor, we confirm the output performance is adequate for robot joint module.
