Doubly-fed electric machine - Wikipedia

2020-2-2 · With its origins in wound rotor induction motors with multiphase winding sets on the rotor and stator, respectively, that was invented by Nikola Tesla in 1888, the rotor winding set of the doubly-fed electric machine is connected to a selection of resistors via multiphase slip rings for starting. However, the slip power was lost in the resistors.

AC Generator – Definition, Construction and Working

Rotor: Rotor is the rotating component of AC Generator. It is also made of laminated steel. DC Field winding or exciting winding is wound on the rotor to create magnetic poles i.e. North and South Poles. This exciting winding is supplied DC current through an assembly of slip ring and carbon brush. There are basically to designs for rotor.

Synchronous Generator Construction | Parts - your

2020-3-26 · A three-phase synchronous generator has three identical windings. Every phase winding is displaced at 120 o electrical apart. When a magnet (rotor) is rotated by means of some prime-mover in these windings, the stator conductors are cut by the magnetic field of the rotor, hence an EMF is induced in each winding. These EMFs are of same magnitude
