The Motor Control Centre is used in general to describe combinations of enclosures, busbars, circuit breakers, power contactors, power fuses, protective relays, controls and indicating devices. Read more about switchgear …
An induction motor may be considered to be a transformer with a rotating short-circuited secondary. The stator winding corresponds to the transformer primary and the rotor winding to the transformer …

Star-Delta starting is frequently referred to as “Soft-starting” a motor. But what is soft about his starting method? Why is it used? What are the advantages? What are the disadvantages? In …
In this post, we will look into the characteristics of a DC series motor. A DC series motor is one type of DC motor in which field winding is connected …
We have already discussed the working of electrical relays. Now we are going through different types of electrical relays. There are two basic classifications of relays: Electromechanical Relays Solid State …
Two types of noises occur in an electric motor, one is electrical noise and the other is mechanical noise. The causes of remedial treatments for both are discussed in this …
Armature reaction also occurs in a DC motor just like armature reaction in DC Generator. This is expected because when current flows through the armature conductors of a DC motor, …
The three-phase induction motors are the most widely used electric motors in the industry. They work on the principle of electromagnetic induction. Due to the similarity in the working principle of the transformer, …
