PERMANENT MAGNET MOTOR WITH FIELD WEAKENING ARRANGEMENT
Patentansökan, 2021

The invention relates to a permanent magnet motor, comprising: a stator configured for generating a time-varying magnetic field; a rotor, arranged inside of the stator, comprising at least one permanent magnet providing a constant magnetic field; the permanent magnet being made of a flexible material; the stator being configured for rotating the rotor by taking along the constant magnetic field of the rotor with the time-varying magnetic field of the stator; the rotor comprising a field weakening mechanical arrangement configured for weakening a flux of the permanent magnet motor; the field weakening mechanical arrangement supporting the permanent magnet and comprising a recess configured for allowing the permanent magnet to be deformed by a centrifugal force provided by the rotation of the rotor.
