Abstract
High speed BLDCM has the advantages of high power density, high efficiency, high speed range and so on, but the traditional BLDCM uses position sensor to obtain the rotor position information, which limits its application. In recent years, the control of BLDCM without position sensor has become a research hotspot. In this paper, a control system for a high-speed permanent-magnet BLDCM is presented. The control system consists of control module, 232 communication, inverter module, PWM driver, detection circuit and RC filter Circuit. Also, software based on ARM is designed to realize the fuctions. Experimental studies are carried out on the prototype to validate stability and reliability of the control system.
