PERMANENT-MAGNET GENERATOR Russian patent published in 2001 - IPC

FIELD: electric power generation. SUBSTANCE: generator has stator running windings uniformly distributed over circumference and fixed in position within its frame. Each winding core has magnetic circuit and salient-field permanent magnet. Gap is provided between magnet and magnetic circuit forming closed magnetic flux to provide for displacement of screens therein. Screens are secured on butt ends of rotor permanent magnets; rotor is made of nonmagnetic material. Quantity of rotor magnets is smaller by one than that of stator magnet and their polarity orientation in magnetic field is different. EFFECT: enhanced efficiency of permanent-magnet energy utilization. 4 dwg
