FIELD: engines and pumps.
SUBSTANCE: invention relates to electric motors, in particular to mobile permanent magnets and/or to non-magnetic conductive shunting parts in a rotor for motor conversion from asynchronous induction motor at starting into synchronous motor. Reconfigurable electric motor contains a rotor with rotary permanent magnets or non-magnetic conductive shunting parts. Magnets and/or the shunting parts have the first position creating weak magnetic field ensuring the motor run in asynchronous mode at its starting, and the second position creating strong magnetic field ensuring an efficient operation in a synchronous mode. The motor also contains a squirrel-cage winding of rotor. At approaching or achieving by the motor of synchronous rotational speed the permanent magnets and/or the shunting parts rotate for creation of strong magnetic field with ensuring of high performance in the synchronous mode.
EFFECT: increase of overall performance.
