Stator Voltage Control of Induction Motor: By reducing Stator Voltage Control of Induction Motor, speed of a high-slip induction motor can be reduced by an amount which is sufficient for…
Pole Amplitude Modulation Induction Motor: Pole changing method as already discussed allows a change of speed by a factor 2. In some applications, speed change is required only by a…
Pole Changing of Induction Motor: Pole Changing of Induction Motor - For a given frequency, the synchronous speed is inversely proportional to the number of poles. Synchronous speed, and therefore,…
Transient Analysis of Induction Motor: Usefulness of analysis of transient operating conditions of a drive, e.g. starting, braking, load changing, speed changing, etc. is already explained. A rigorous analysis of…
Dynamic Braking of Induction Motor(or Rheostatic Braking): (a) AC Dynamic Braking - AC Dynamic Braking of Induction Motor is obtained when the motor is run on a single phase supply…
Starting of Induction Motor Drives: Starting of Induction Motor Drives arrangement is chosen based on the load requirements and nature of supply (weak or stiff). It may be required to…
Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two…
Chopper Control of Series Motor: Motoring : Chopper Control of Series Motor and va and ia waveforms will be same as shown in Fig. 5.41. Va is given by Eq. (5.113). However,…
