ABSTRACT:
A control for a variable reluctance motor, comprising a d.c. source, a power control circuit, and a command circuit, in which the power control circuit comprises main control switches in series with the windings of the motor to form terminal branches, the terminal branches being connected in groups of two in series between the two poles of the source in such a way that two complementary windings are never in series, as well as free-wheel branches to close the circuit of each winding when at most one main control switch in a branch is conducting, and a turn-off circuit for the main control switches, and including at least one current detector to register the current in the windings; each free-wheel branch includes a coil and a diode, the diode polarized to oppose normal current flow through its associated main control switch.
