DC Series Motor Starter Working Principle: The series motor starter serves the same purpose as the three- and four-point starters employed with shunt and compound wound motors. However, series motor…
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…
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.…
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).…
Special Features of Thyristor Drive Motors: The most commonly used dc motors for thyristor drive are separately excited and series excited dc motors. The thyristor drive motors usually differ from…
