Single-phase motors are used when a three-phase system is not available and/or for limited power – they are generally used for powers under 2 Kw or 3 Kw. Three-phase motors commonly see more use in industry, since their power is over 150% greater than that of a single-phase motor, and a three-phase rotating magnetic field is generated. While running a single-phase motor can be noisy and

Electric motor - 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.
