The invention discloses a magnetic levitation type hub motor, and the hub motor comprises a motor rotor shell, an end face permanent magnet array, a side face permanent magnet array, a side face three-phase coil array, an end face three-phase coil array, a motor stator shaft and a Hall sensor. The inner wall of one end face of the motor rotor shell is evenly and fixedly connected with an end face permanent magnet array. The periphery of the inner side surface of the motor rotor shell is fixedly connected with a side surface permanent magnet array; a motor stator shaft is arranged between the end surface permanent magnet array and the side surface permanent magnet array. According to the invention, six-degree-of-freedom motion can be realized, and the position of the motor rotor can be adjusted more flexibly; the rotating speed of the electromagnetic field is consistent with that of the rotor, so that the rotating speed of the motor is stable, and the motor has good motion precision; in addition, in the moving process of the magnetic suspension type hub motor, the stator and the rotor are not in direct contact, no friction force exists, and therefore energy loss caused by friction does not exist.
