generators and motors notes.notebook March 31, 2017 Electric Motors and Generators Electric Generators • Use electromagnetic induction to change mechanical energy into electrical energy. • The electric current changes direction each time the coil makes a half turn. This is called alternating current. Examples of Generators • Nuclear Power Plant uses thermal energy from nuclear reactions to make steam, which powers a turbine. • Power Plants burn coal or oil to make steam to drive the turbine. • Wind wind power makes a magnet spin inside a coil of wire. • Hydroelectric falling water turns the turbine.
