Development of A F28335-based Miniaturized Brushless DC Motor Servo Controller

A novel miniaturized brushless DC motor servo controller with high performance is proposed. The controller adoptTMS320F28335 as the core processor, and design three-phase full-bridge driving circuit, undervoltage sampling circuit and overcurrent sampling circuit. It has the capability of high-speed communication with the host via CAN bus and real-time data exchange, and achieve the digital control of speed and position by applying PID algorithm. The experiment results show that the development of the controller is successful, and it is primary meet the driving and control requirements of small and medium-sized BLDCM which below 200W.
