摘要
以SPCE061A单片机为控制核心,结合专用芯片LM621,开发出一种新型无刷直流电动机控制系统．给出了硬件构成和软件设计方案,并在实验运行过程中获得了预期的效果．当PWM输出波的频率为2 kHz时,实验特性和理想特性基本吻合．可语音播报电机转速是其一个较大特色．
By using the microcontroller SPCE061A and the chip LM621, a new control system of the brushless DC motor is designed. The hardware structure and software design are introduced. The expected effect of the control is gained through experiments. When the PWM frequency is equal to 2 kHz, the experimental characteristic is basically according with the academic characteristic. The rotate speed which can be speaked out is the most signifcant characteristic of this system.
