DoubleFed Induction Generator

Inductiontype generators are widely used, known to be relatively simple, robust and costeffective. In fact, since 1998, Bonus has had a 1 MW machine operating with variablespeed pitch control and a full converter. We are of the opinion that a full converter is better suited for offshore appliions than the doubly fed systems common today ...

electric motor

 · electric motor electric motor Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 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.

Three Phase Induction Motor Construction

Induction machines are also called asynchronous machines the machines which never run at a synchronous speed. Whenever we say induction machine we mean to say induction motor. Induction motors may be singlephase or threephase. In this article, I am discussing about three phase induction motor construction.
