Voltage Source Inverter Control of Induction Motor

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. Voltage Source Inverter Control of Induction Motor are described here and cycloconverter fed drives. VSI Induction Motor Drives: Voltage Source Inverter Control of Induction Motor

Pole Changing of Induction Motor

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, motor speed can be changed by changing the number of poles. Provision for changing the number of poles has to be incorporated at the manufacturing

Transient Analysis of Induction Motor

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 transient operation of an induction motor drive, can be done only by the d-q axis model involving long calculations. A simple method of analysis, with

Dynamic Braking of Induction Motor

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 by disconnecting one phase from the source and either leaving it open (Fig. 6.15(b)) or connecting it with another machine phase (Fig. 6.15(c)). The two
