Traction And Braking

Speed Control of DC Motors: the speed of a motor is given ...

traction. The number of series filed turns in the circuit can be changed. With full field, the motor runs at its minimum speed which can be raised ... Rheostatic or Dynamic Braking: In this method, the armature of the shunt motor is disconnected from the supply and is connected across a variable resistance R. The field winding is left connected
