What is an Electric Motor ?

Electric Motor Definition

An electric motor is a device that converts electrical energy into mechanical energy using magnetic fields and electric currents.

Core Functioning

The main principle behind all electric motors is Faraday’s Law of induction, which describes how a force is generated from electrical and magnetic interactions.

Types of Electric Motors

DC Motors
Synchronous Motors
3 Phase Induction Motors (a type of induction motor)
Single Phase Induction Motors (a type of induction motor)
Other special, hyper-specific motors

How do I change the motor orientation in a star triangle connection?

How do I change the motor orientation in a star triangle connection?

In a Star-Delta or Y-delta connection, changing the direction of the motor can be achieved by changing the phase sequence applied to the motor windings. The direction of the motor depends on the power supply phase sequence, that is, the order in which the three phases of the power supply reach the motor winding. The following are the specific operation steps and principles:Star connection (Star/Y connection)Star connection principle: In a star connection, one end of the three windings is connect

Armature Winding

Armature winding definitionThe armature winding in an alternator is the arrangement of coils to generate electricity and is essential to its operation.Type of armature windingSingle-phase armature windingSingle-phase armature windings can be centralized or distributed.Centralized armature windingWhen the number of slots on the armature equals the number of poles in the machine, the central winding is used. This winding type provides maximum output voltage, but is not always fully sinusoidal. The
