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 a repulsion-start induction motor is…
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, to improve power factor and…
Repulsion Motor - Construction, Working Principle and Applications: The characteristics of repulsion motors are similar to those of a series motor, i.e., high starting torque and high light-load speed. Its construction is also similar to…
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 or ac of approximately same…
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 degrees apart. The main or running winding is…
Capacitor-Start Capacitor-Run Single Phase Induction Motor: The capacitor-start capacitor-run motor is similar to capacitor-start, induction-run motor, except that the auxiliary winding and a capacitor remain connected in the circuit at all times. Of course, such…
Resistance Start Single Phase Induction Motor: It is a form of split-phase motor having a high resistance connected in series with the auxiliary or starting winding, as illustrated in Fig. 1.38 (a). A typical torque-speed…
Three Phase AC Shunt Commutator Motor: The connection diagram of a three phase ac shunt commutator motor is shown in Fig. 1.37. In this motor, the stator is connected directly to the supply while the…
Three Phase AC Series Commutator Motor: This machine has a 3-phase stator winding similar to that of an ordinary induction motor and may be wound for high voltage if required. The rotor carries a winding…
Compensated Induction Motor (No-Lag Type Motor): This is an improvement of the plain induction motor designed to operate at approximately unity or slightly leading power factor over the whole range of loads. The usual type…
