ELECTRIC DRIVE WITH SYNCHRONOUS RELUCTANCE MACHINE Russian patent published in 2014 - IPC H02P27/04 

FIELD: electricity.

SUBSTANCE: invention refers to electrical engineering and can be used, for instance, in controlled electric drives of general-purpose industrial machinery and transportation vehicles. Electric drive with synchronous reluctance machine contains two groups of full-pitch polyphase windings distributed evenly along inner stator bore, at that windings of similar stator phases are interconnected in series so that special magnet axes of these winding area mutually orthogonal; beginnings of the first group windings are connected to the supply mains, while ends of the second group windings are connected to input of the non-controllable rectifier, rotor position sensor. Between anode and cathode groups of the rectifier through current sensor there are parallel-connected capacitor and a circuit consisting of in-series transistor switch with bypass diode and choke with bypass diode; output of current regulator is connected to control input of transistor switch, output of commutator switch is connected to its first input and output of current sensor is connected to its second input; the first input of commutator switch is connected to current source of preset value, while its second input is connected to output of the metre metering special voltage vector position at the engine stator, the third input is connected to output of rotor position sensor; outputs of the metre metering special voltage vector position at the engine stator are connected to phase clamps of three-phase power supply source.

EFFECT: improving quality of control processes.
