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 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 deÂgrees 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 improveÂment 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…
Schrage Motor - Connection Diagram, Advantages, Disadvantages and Applications: Variable Speed Commutator Type 3-Phase Induction Motor (Schrage Motor). This is also an improvement of the plain induction motor designed to provide a variable speed. It…
Electric Motor Speed Torque Characteristics: A Electric motor speed torque characteristics is defined as the relationship between the speed at which it operates and the torque it develops, ω = f(T). Practically all electric motors—shunt wound,…
