Braking the electric motor: methods and schemes

Braking of the electric motor is used if it is necessary to reduce the free run-out time and the fixation of the mechanism in a specific position. There are several types of forced stopping of the device. It is mechanical, electrical and combined. The mechanical device is a shaft-mounted brake pulley with pads. After disconnecting the device, the pads are pressed against the pulley. Due to fric...

Adjusting the speed of an asynchronous motor: methods and schemes

Due to the reliability and simplicity of design asynchronous motors (AD) are widespread. Most machine tools, industrial and household equipment use this type of electric motors. The change in the speed of rotation of the IM is performed mechanically (by additional load on the shaft, ballast, transmission mechanisms, gearboxes, etc.) or electrically. Electrical regulation is more complex, but al...
