Has relatively wider range of speed control
WebMar 12, 2014 · Generally, this method permits to increase the speed in the ratio 3:1.Wider speed ranges tend to produce instability and poor commutation. Advantages of flux control method: (i) This is an easy and convenient method. (ii) It is an inexpensive method since very little power is wasted in the shunt field rheostat due to a relatively small value of ... WebFrom the above equation, the speed of the motor depends on supply voltage (V), Flux (Φ), and Armature resistance (Ra). Therefore, the speed of a DC motor can be varied, changed and controlled by changing; Terminal voltage “V” (AKA Applied Voltage Control Method). External resistance with armature resistance Ra (AKA Rheostatic Control Method).
