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 …
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, …
Electric Motors need maintenance regularly in order to avoid failure and prolong their lifespan. Generally, motors and motor parts should be maintained and tested at least every 6 months. Then …
Insulation Resistance or IR Test is carried out by maintenance engineers to ensure the healthiness of the overall insulation system of electrical equipment. It reflects the presence or absence of …
Before going to the operation and characteristics of split-phase induction motor we should first understand why single phase induction motor is not self-starting. To make a single-phase induction motor self-starting, …
