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…
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…
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…
Motor Rating Various Duty Cycles: From the point of view of calculation of motor rating various Motor Rating Various Duty Cycles can be broadly classified as: Continuous duty. Fluctuating loads.…
Selection of Motor Power Rating: The Selection of Motor Power Rating of a motor for a specific application must be carefully chosen to achieve economy with reliability. Use of a…
