ENERGY CONVERTER Russian patent published in 2001 - IPC

FIELD: electrical-to-mechanical energy conversion in vibratory drive motors, stepping motors, and the like. SUBSTANCE: energy converter has stator magnetic core with poles, rotor mounted for displacement along poles and isolated from stator core by air gap, stator winding wound on magnetic core, power supply, diode, controlled switch, initial rotor position sensor, and intermediate rotor position sensor. Power supply 6 is disconnected from diode in response to signal coming from intermediate rotor position sensor which shorts out the winding with the result that energy conversion takes place at constant flux linkage. EFFECT: enhanced power characteristics. 4 cl, 3 dwg
