碩士 === 大葉大學 === 電機工程學系 === 101 === In this study, we present a design method of a permanent magnet brushless DC motor drive. The architecture includes a bridge rectifier circuit from AC to DC, an inverter for motor operation, and PWM signal modulation for speed control. The control kernel uses a microcontroller combining analog and digital control technology to adjust the PWM module. This study integrates brushless DC motor control and drive module design. The driver has been successfully used in 750W PMBLDCM for industry applications. The motor are tested based on a dynamometer testing system, waveforms under applying nominal load are measured at rated speed 4200rpm. The experimental results show that the motor drive system has good performance.
