Device for operating low-voltage ranges for a high-speed induction machine, uses a three-point current converter as an electronic power servo component.

摘要

A regulator (4) adjusts an intermediate circuit current that is constant and connects in the form of a block with a block operating control (5) onto the lanes for a motor (1) via a two-point current converter. In three-phase induction machines the block width amounts to 120 deg . Block-formed lane currents involve harmonic oscillations that cause a motor coupled in to experience losses of copper and iron in the stator and rotor for the induction machine. An Independent claim is also included for an application for the present invention with an induction machine fed by a three-point current inverter.
