Electrical Machine

• An electrical machine is a device that converts mechanical energy into electrical energy or Electrical energy to mechanical energy. 

• Electrical machines also include transformers, which do not actually make conversion between mechanical and electrical form but they convert AC current from one voltage level to another voltage level

  Types of Electrical Machine

     (1).Static machine

     (a). Transformer

     (2).Dynamic machine

     (b). Generator

     (c). Motor

• 1. Static machine: An machine consists of the combination of two materials, which when rubbed together produce static electricity, and of a third material or object which acts as a collector for the charges,The charge is produced by inductance, usually between two or more glass plates.

         Ex: Transformer

• (a). Transformer: A transformer is a static device that transfers electrical energy from one circuit to another through the process of electromagnetic induction.
