Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Drive Circuits for Stepper Motor: A Drive Circuits for Stepper Motor is usually driven from a low voltage dc source. When a phase is to be energised, the dc source…
Self Controlled Synchronous Motor Drive: A Self Controlled Synchronous Motor Drive employing a load commutated thyristor inverter is shown in Fig. 7.10. In large power drives wound field synchronous motor…
Closed Loop Speed Control of Induction Motor Drives: A Closed Loop Speed Control of Induction Motor Drives is shown in Fig. 6.43. It employs inner slip-speed loop with a slip…
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…
