The present invention discloses a construction method of a bilateral suspension motor. By using the Fourier decomposition method to analyze the magnetic field pole pairs of the permanent magnet in the air gap, the suspension winding is wound to generate a stable suspension force. First, determine the permanent magnet pole pairs and the number of modulation blocks of the motor, then modify the magnetic potential of the permanent magnet into a sine wave, and use Fourier decomposition to determine the fundamental wave pole pairs and rotation speed of the permanent magnet in rotation and at rest. According to the conditions for generating the suspension force, screen out possible suspension winding winding methods. Finally, according to the proposed constraint condition (n r -p s ) = p s ±2 and the principle that two magnetic fields with a difference of one pair of poles generate suspension force pulsation to determine the optimal suspension winding winding method. The suspension winding winding method provided by the present invention can set the winding of a specific suspension winding on the outer stator under the condition of determining the stator and rotor structure of the bilateral motor, so as to reduce the pulsation of the suspension force of the motor and generate a relatively stable suspension force.
