ELECTRIC MOTOR AND/OR GENERATOR WITH MECHANICAL TUNING OF MAGNETOSTATIC FIELD Russian patent published in 2015 - IPC H02K21/12 H02K1/27 

FIELD: engines and pumps.

SUBSTANCE: invention relates to electric motors and generators, in particular to regulation of a position of permanent magnets and/or of shunting inserts made from non-magnetoconductive material, in a rotor. AC motor or generator contains fixed windings (or stator), located around a rotor with permanent magnets. The permanent magnets are usually made cylindrical and they have two magnetic poles. Magnetoconductive loops are formed by magnets located in magnetoconductive pole terminals. During rotation of permanent magnets and/or shunting inserts made from conductive non-magnetic material, in pole terminals the force of resulting magnetic field for torque (at low speed) or efficiency (at high speed) regulation of AC motor or generator is increased or decreased. By change of a rotor magnetic field the voltage output of AC generators is regulated with a possibility of ensuring, for example, of constant voltage at the output of the generator with wind motor.

EFFECT: increase of overall performance at various rotational speeds.
