High-speed motor system

High speed motor system, the motor belongs to the field of the present invention is a solution using an electromagnetic damper generates damping force vibration reduction system, requires the installation of a magnetic damper ends of the rotor, thus increasing system size and losses; Further, the damping force acting on the ends of the rotor, the rotor and the vibration amplitude is generally the maximum axial intermediate point, so the damping effect is difficult to achieve the best question. The present invention comprises a double winding alternating current motor, the primary power converter and a control unit; double winding AC motor comprising a stator and a rotor, the stator comprising a stator core and a stator winding, a cylindrical stator core, the stator winding is a main winding and the secondary double winding structure of the winding configuration; the primary winding lead wire connecting the main power converter; said secondary lead means connected to the control winding.
