The objective of this project is to build a simple electric motor

Electric motor Construction of induction motors

Electric motor Construction of induction motors The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
