摘要： A system for decoupling a rotor from a stator of a permanent magnet motor and a flywheel storage system using the same are provided. The flywheel storage system uses the permanent magnet motor as a magnetic active coupler to minimize magnetic losses in flywheel energy storage system during the motor-generator electric power transfer for enabling a magnetic field weakening method and a way of cancelling the losses during a conservative mode where the stator is totally decoupled from the rotor. Also, the present invention enables the optimal sizing of a permanent motor-generator to be able to supply a constant power over a large range of rotating speeds.
