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 is meant by electrical machine?
In electrical engineering, electric machine is a general term for machines using electromagnetic forces, such as electric motors, electric generators, and others. … The moving parts in a machine can be rotating (rotating machines) or linear (linear machines).
What are examples of electrical machines?
