Customized power tool motors, power tool motors are mostly series-excited motors with brushes inside. The motor has the characteristics of small size, high power and high speed. But can't work long hours. Most of the motor speed control of electric tools is the same, and the speed is adjusted by outputting a mechanical deceleration mechanism. The speed-regulating motor consists of a tapered driving wheel and a pressure plate that are compressed by a set of disc springs. The input shaft and the driving wheel are connected by a key to form a compressed driving device. A set of tapered planetary friction wheels are sandwiched between the compressed driving wheel and the pressure plate on the inside, and the outer side is sandwiched between the tapered fixed ring and the speed control cam to form a friction pair; when the compressed driving device is running At this time, the friction wheel does pure rolling. Because the fixed ring and the speed control cam do not move, the friction wheel revolves while rotating, and drives the planet carrier to rotate through the central shaft of the planetary friction wheel and the slider bearing.
