SYNCHRONOUS MOTOR, ENCODERLESS MOTOR SYSTEM AND A METHOD FOR OPERATING AN ENCODERLESS MOTOR SYSTEM WITH A SYNCHRONOUS MOTOR |
摘要 |
The invention relates to a synchronous motor (12) with a number of stator coils (15), with a rotor (16) with at least one permanent magnet (17), which induces a rotor magnetic field in a useful flux direction and with at least one coil winding (20), which is fitted on the rotor in order to induce a resultant magnetic field as a result of an alternating magnetic fields which is applied with the aid of the stator coils, in the direction of a winding axis of the coil winding, so that a resultant inductance of the stator coils (15) with respect to a direction of the winding axis is different given different positions of the rotor (16). |
