Inductor Generator

inductor generator

[in′dək·tər ′jen·ə‚rād·ər]
An alternating-current generator in which all the windings are fixed, and the flux linkages are varied by rotating an appropriately toothed ferromagnetic rotor; sometimes used for generating high power at frequencies up to several thousand hertz for induction heating.

Inductor Generator


an AC electric machine in which the movement of a toothed ferromagnetic rotor causes a change in the magnetic flux permeating the stator winding. The excitation field is generated by a winding connected to a DC supply. The field and operating windings are mounted in a fixed position on the stator.

A distinction is made between inductor generators with a pulsed field, in which the magnetic field changes in magnitude but not in polarity, and generators in which the magnetic field changes in both magnitude and direction. Generators with a pulsed field are made in single-phase and three-phase types; the frequency of the current generated can be as high as 10 kilohertz (kHz). Generators of the second type are made only in single-phase types; the frequency range is 10–20 kHz. Inductor generators are always coupled to a driving motor and are used mainly for frequency conversion of electric currents.
