DRILL WITH SOLID STATE SPEED CONTROL AND METHOD OF OPERATING
摘要
A power tool includes solid-state motor control. The tool includes a solid state variable speed control signal generator for generating a variable speed control signal, a microcontroller for generating a pulse width modulated (PWM) signal corresponding to the variable speed control signal, a driver circuit for generating H-bridge driving signals corresponding to the PWM signal, and an H-bridge circuit for selectively coupling a motor to a power source in accordance with the H-bridge driving signals.
