3 Point Starter and 4 Point Starter -Construction and its Workings: The starter for a shunt motor (3 point starter) is shown in Fig. 1.59. At start all resistances are…
Starting of Electric Drives: The most important processes associated with controlled electric drives are (i) starting, (ii) speed control (iii) braking, (iv) reversal of direction of rotation. All these are…
Repulsion Induction Motor - Construction, Working Principle and Applications: The repulsion induction motor has a single phase stator winding, as a repulsion-start induction motor has, but it has two separate…
Repulsion Start Induction Motor - Working Principle: As the name implies, the repulsion-start induction motor starts as a repulsion motor and runs as an induction motor. The general construction of…
Compensated Repulsion Motor - Construction and Working Principle: Compensated Repulsion Motor is a modified form of the repulsion motor. It is provided with an additional winding, called the compensating winding,…
Repulsion Motor - Construction, Working Principle and Applications: The characteristics of repulsion motors are similar to those of a series motor, i.e., high startÂing torque and high light-load speed. Its…
Universal Motor - Construction, Working Principle and Applications: A universal motor is a specifically designed series wound motor, that operates at approximately the same speed and output on either dc…
Permanent Capacitor Single Phase Induction Motor: Permanent capacitor single phase induction motor, also sometimes called the single-value capacitor—run motor, has two stator windings placed mutually 90 electrical deÂgrees apart. The…
