Electrical Machines

Electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others.

There are mainly three types of electrical machines. 

  1. Generator 
  2. Electric Motor
  3. Transformer

Generator

A generator converts mechanical energy into electric power.

Electric Motor

Electic motors use electrical energy to produce mechanical power.

Transformer

Transformer transfers electric power from one circuit to another.

Generators

An electrical machine converting mechanical energy to electricity is called a generator

Types of Generator

A direct-current (DC) generator is a rotating machine that supplies an electrical output with unidirectional voltage and current.

Alternator

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current.

Electric Motors

An electric motor is an electrical machine that converts electrical energy into mechanical energy.

Types of Electric Motors

DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. 

Induction Motor

Induction Motors are the most commonly used AC motors in most of the applications. These are also called as Asynchronous Motors.

Synchronous Motor

Synchronous MotorA synchronous motor is another type of AC motor which runs in synchrounous speed.

Transformer

A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.

A substation include transformers to change voltage levels between high transmission voltages and lower distribution voltages.

Transformer Testing

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current.
