Servo Motor Control System and Method of Auto-Detection of Types of Servo Motors

Abstract

Mixture of DC brushed motors and DC three-phase brushless motors has been employed in complicated robotic systems, in order to control different types of motors may using commercial chipsets. Although these commercial chipsets are capable of driving different types of motors, the users are required to define the type of motors they are controlling through software. Defining the type of motors wrongly may damage the motors. Moreover, if a motor is replaced by another type, users would need to modify the software. The paper provides an auto-detection module that can be employed in a servo motor control system with a hybrid commutation control, wherein the hybrid commutation control can drive either a DC brushed motor or a DC brushless motor.
