The electric machines are of three main types, transformer, generator, and motor. Electrical Transformer: In the transformer, both input and output are electrical

An electrical machine is a device which converts mechanical energy into electrical energy or vice versa. 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.

What was the first electric machine?
The first commutator DC electric motor capable of turning machinery was invented by British scientist William Sturgeon in 1832. Following Sturgeon’s work, a commutator-type direct-current electric motor was built by American inventor Thomas Davenport, which he patented in 1837
