Voltage Source Inverter Control of Induction Motor: Variable frequency and variable voltage supply for induction motor control can be obtained either from a voltage sourve inverter (VSI) or a cycloconverter.…
Variable Frequency Control of Induction Motor Drive: Variable Frequency Control of Induction Motor Drive - Synchronous speed, therefore, the motor speed can be controlled by varying supply frequency. Voltage induced…
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…
Braking of Induction Motor Drive: Following methods are employed for Braking of Induction Motor Drive: Regenerative braking Plugging or reverse voltage braking Dynamic (or rheostatic) braking further categorised as: ac…
