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…
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…
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.…
Selection of Electric Drive: For selection of electric drive motor it is essential that the conditions of service are well known. It is not sufficient to simply specify the output…
Types of Electric Drives: The various types of electric drives used in industry may be divided into three types, namely Group Drive, Individual Drive and Multi-motor drives. 1. Group Drive:…
Electric Braking of Separately Excited DC Motor: The electric braking of separately excited dc motor is show in Figure 3.31. Figure 3.31 (a) illustrates a simplified representation of a single…
Protective Devices and Interlocks: Protective devices must be incorporated in the control circuit (or circuits) to interrupt the flow of current to the motor to guard against overloads or other…
