Abstract:
An driving motor with hybrid excitation of electromagnetism and invisible magnetic pole, wherein each magnetic pole comprises two first magnets, one second magnet and one third magnet; wherein the first magnet is placed along a diameter direction of a rotor core, the second magnet is located at a middle and lower portion of two first magnets of each magnetic pole corresponding to the second magnet at a diameter direction, and a magnetic isolation groove is disposed at an inner end of the first magnet and extends toward two sides of the inner end of the first magnet. The magnetic isolated air gap can adjust a spatial distribution of a magnetic field generated by permanent magnets of each pole to replace the permanent magnets, so as to save the number of the permanent magnets, reduce the weight of the motor, and reduce the cost of the motor.
