The type of motor that operates on both DC and single phase AC supply is called Universal Motor. The universal motor is also called an ac series motor. The universal motor works at approximately the same speed and output on…
The types of single phase induction motors are often classified by the names of the starting method used. Like Capacitor start Induction run motor (CSIR), Capacitor start capacitor run induction motor(CSCR), Permanent-split capacitor motor. A standard single-phase stator has two windings placed at an…
3 point starter is used for shunt and compound DC motor. it is called a three-point starter because it has three terminals named L, F, and A. The terminal named L must be connected to either side i.e the positive or negative side…
What is Soft Starter? Soft Starter is starting device, used for the acceleration, deceleration, and protection of the three phase electrical induction motors through the controlling applied voltage to 3 phase motor.Induction motor is the most frequently used motor for…
While selecting an induction motor, Motor Duty Cycle must be considered to meet the induction motor application requirement. The duty types are indicated on motor nameplate data by S1, S2… In the absence of an indication of the rated duty…
The Scott connection of the transformer is a standard method of connecting two single-phase transformers to perform the three-phase to two-phase conversion and vice versa. Scott connection of transformer is also known as T – T connection. In Scott-T connection, two…
Voltage control is performed by changing the transformer turn ratio. This is achieved by providing Tapping on the transformer winding. In a tap changing transformer, taping is either provided on the primary or on the secondary winding of the transformer.…
