BLAC Drive System for Electro-Magnetic Brake

The field of electric braking has focused its attention on braking force obtained by using a motor instead of a hydraulic brake which has been adopted by previous automobile systems. Electric braking is a system which consists of fewer numbers of components than previous hydraulic brakes, and it has effects of improved responsiveness and reduced braking distance for the ABS (anti-lock brake system) and the ESC (electronic stability control). The purpose of this paper is to develop BLAC motor drive system for electro-magnetic brake (EMB). In order to achieve the purpose, this paper shows a control system constituted by a power converter system which drives a motor and a digital control system which controls the speed, and it suggests a vector control strategy for a fast torque response. Furthermore, this paper applies the control technique and verifies the performance of BLAC motor drive system for EMB while providing the result of experiment as well as simulation by Matlab/Simulink.
