Chapter 43, Problem 1RQ

To determine

The three methods of breaking a motor.

Expert Solution & Answer

Explanation of Solution

The electrical motor uses three types of braking the mechanical braking, dynamic braking and the Plugging.

Mechanical braking

In mechanical braking there are two type breaks drum and disc. In drum the pressure is applied to the metal cylinder called the drum by the help of break shoe. The drum is connected to the motor shaft. The pressure on the drum stops the motor from rotating. The disc rakes is most common braking, its working is similar to drum brake with difference that the brake pads exert the pressure on the spinning disc.

Dynamic braking

The dynamic braking is used to limit the dc motor and ac motor speed, in this method the motor supply is cut and rotating motor is connected across a load the power so produced is dissipated in the load thus stopping the motor.

Plugging

The plugging is the method used by the dc motor with the squirrel cage motor in this method. This is done by reversing the magnetic field in which the motor is operating. The reversing of the field reduces the speed and hence the motor.
