Analysis the electromagnetic torque and magnetic field of the axial and tadial air gap hybrid magnet circuit multi-coupling motor

An axial and radial air gap hybrid magnet circuit multi-coupling motor is produced based on permanent magnet inductor type synchronous motor. In this paper the magnetic network model of the motor is established. The analysis shows that the static torque of the axial and radial air gap hybrid magnet circuit multi-coupling motor is composed of permanent torque, reluctant torque and axial coil torque, which is much higher than that of permanent magnet inductor type synchronous motor. And the control of the motor is much more complex than that of permanent magnet inductor type synchronous motor. In this paper the electromagnetic torque and magnetic field of the motor is studied.
