WebThe speed of a DC motor can be controlled by changing the flux applied to it as the speed of the motor is inversely proportional to the flux per pole. To control the flux, a variable resistor or a rheostat is added in series with the field winding. Increasing the resistance will increase the speed as it will decrease the flux. WebThe rotational speed of this magnetic field is directly proportional to the frequency of the AC power, and inversely proportional to the number of poles in the stator: S = 120 f n Where, S …
