SINGLE-KEY MULTIPHASE ELECTRIC DRIVE Russian patent published in 2019 - IPC H02K29/00 H02P25/86 

FIELD: electromechanics; engines.

SUBSTANCE: invention relates to the field of electromechanics, namely to the electric drive with a multiphase valve-inductor motor (VID), and is intended for actuation of machines and mechanisms. Technical result is achieved by the fact that single-key multi-phase electric drive containing two capacitors, three diodes, PC and VID with stator winding divided into two parts, two constant voltage sources, wherein the plus of the first source is connected to the positive of the first capacitor, to the diode anode, the cathode of which is connected to the beginning of the first winding part, to the diode cathode; minus second source is connected to negative of second capacitor, to end of part of second winding, to anode of diode; that in circuit for each of n phases there added is 2 diodes, connected as follows: cathode of the first diode is connected to minus of first source, anode is connected to first terminal of PC, to negative of first capacitor, to diode anode, cathode of which is connected to beginning of part of second winding; anode of the second diode is connected to the positive of the second source, the cathode is connected to the second terminal of the PC, the positive of the second capacitor and the end of the part of the first winding, besides, the number of phases connected to the sources is not limited and equals 1, 2, …, n. In the proposed electric drive circuits of currents of different phases are separated from each other, which ensures operability of multiphase LED, and namely enables to switch phases at different times.

EFFECT: technical result achieved by invention consists in expansion of functional capabilities of single-key electric drive for multiphase valve-inductor drives.
