Abstract: A disk-shaped multi combined three-dimensional permanent magnet motor is provided. Two independent disk-shaped stators are respectively provided on a left side and a right side in a shell. A disk-shaped rotor with permanent magnets adhered on both a left face and a right face thereof is provided between the two independent disk-shaped stators. Spindle hole in the center of the rotor is coupled with a spindle of the main dynamical axis. Nine motor winding coils provided in side face slots of the disk-shaped stators are a unit for one motor. The left and right stators serve as one group to determine pole-pairs number of the motor which further determines numbers of the permanent magnets adhered. The motor is capable of driving load at low speed and meeting the function requirements of low-speed and high torque, which greatly improve efficiency of the whole machine.
