Note The stator of a synchronous motor is wound for the same number of poles as the rotor poles. Thus, for a dc generator, input power is in the form of mechanical and the output power is in the form of electrical. A dc generator converts mechanical power into electrical power and a dc motor converts electrical power into mechanical power. The electric machines are of three main types, transformer, generator, and motor. An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. It uses Faradays law of electromagnetic induction. Synchronous circuits are used in counters, shift registers, memory units. An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current.

What is an Armature? gen is nothing but The speed of the synchronous motor is independent of the load, i.e., the variation of the load does not affect the speed of the motor. A synchronous generator is a synchronous machine which converts mechanical power into AC electric power through the process of electromagnetic induction.. Synchronous generators are also referred to as alternators or AC generators.The term "alternator" is used since it produces AC power. It consists of a field winding and armature winding.

Brushless linear motors are members of the Synchronous motor family. Types Brushless. a motor or generator) that carries alternating current (AC). Alternator and Synchronous Generator Formulas & Equations. As the name suggest, the synchronous motor has a rotor that is designed to rotate at the same speed as its stator rotating magnetic field called synchronous speed. If one puts a permanent magnet in such a set of stators, it becomes a synchronous three phase motor. Copy and paste this code into your website.
