Abstract: At present,brushless DC motor(BLDCM) is widely used in many smart devives such as small aerial photograph drone and sweeping robot,it has many advantages,such as small size, high reliability and high pullin torque. A BLDCM servo control system was introduced,which was mainly used for camera stable gimbal. The system used a magnetic encoder to detect the rotor position,and used linear current sensors to detect twophase current,the motor control scheme was based on Field Oriented Control(FOC).Experimental results show that the system represses torque ripple effectively through the application of highprecision sensors ,the motor runs smoothly,robust and accurate.
Key words: BLDCM; stable gimbal; magnetic encoder; torque ripple; field oriented control; servo system
