SCHALTUNGSANORDNUNG ZUM KOMMUTIEREN EINES RELUKTANZMOTORS

摘要

A commutating circuit for a reluctance motor having a stator, which is provided in a first cyclic arrangement along a movement coordinate for a rotor which can move with respect to the stator with a number of windings, into which current pulses of a length and position which can be predetermined with respect to the movement coordinate of the rotor can be supplied in a corresponding cycle, as a function of the position and movement speed of the rotor, ensures correct commutation, even at very high speeds, and hence a high torque and low losses, with a simultaneously simple circuit construction, in that, at movement speeds above a predeterminable value, at least the current pulse following in the cyclic sequence predetermined for low movement speeds is omitted after each supplied current pulse.
