【Abstract】 In this paper,the basic structure and main character of Permanent Magnet Brushless DC Motor(BDCM)is analyzed,and an analog integrate circuit to control the motor is introduced in detail.A high efficiency three-phase square-wave voltage Pulse Width Modulation (PWM) is gained,and the dead time of PWM can be set conveniently,which makes the system safely and reliable.Intelligent Power Module (IPM) amplifies the PWM wave to drive the motor,which improves the integrated level of the system further.The experiment result confirms the high performance of the control system.更多还原
