【Abstract】 A BLDCM controller which was composed of switch power supply,PWM modulating chipset and hardware logic gates circuits were introduced,and the motor controller was used to control electric motorcycle with high-power outputs.The system adoptsed some over-current, over-voltage protection and current cut-off feedback circuits to improve system’s reliability.The experiments showed that the controller has a compact structure, perfect function, low cost and high-reliability.It also realized the control of BLDCM with high-power outputs and met the demands when electric motorcycle was continuously speed controlled.更多还原
