Description

Technical field [0001] The invention relates to a magnetic leakage type mechanical variable flux permanent magnet synchronous motor, which belongs to the technical field of motor manufacturing. Background technique [0002] With the continuous improvement of the comprehensive utilization and development of new energy and renewable energy, the ability to provide stable power quality or a wide range of motor speed has gradually become a key factor in determining energy conversion efficiency, and the flexible adjustment of the motor magnetic field is One of the important technical means to ensure efficient energy conversion. [0003] With the change of the rotor position, the magnetic flux of the magnetic flux switching motor will automatically switch the path, so that the polarity and magnitude of the magnetic flux passing through the coil will change, thereby generating alternating induced electromotive force. This type of motor has small size and light weight , Reliable work, conv...
