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…
Brushless DC Motor Drives(Trapezoidal PMAC): The cross section of a 3-phase 2 pole Brushless DC Motor Drives is shown in Fig. 7.15. It has permanent magnet rotor with wide pole…
Sinusoidal PMAC Motor: Since the voltages induced in the stator phases of a sinusoidal PMAC motor are sinusoidal, ideally, the three stator phases must be supplied with variable frequency sinusoidal…
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…
Working Principle of Linear Induction Motor: While the conventional induction motor gives rotary motion, a Working Principle of Linear Induction Motor provides translational or linear motion. Hence it is termed…
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…
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…
