Analysis of Influence Factors on Axial Magnetic Force of Conical-rotor Permanent Magnet Synchronous Motor for Electric Aircraft Propulsion
This paper proposes a conical electric propulsion motor scheme to address the issue of axial force wear on electric propulsion motor bearings,which utilizes the axial force of the conical motor to balance the axial force of the propeller.In this paper,a magnetic circuit model is established for the electric propulsion conical-rotor permanent magnet synchronous motor,and the mathematical expressions of related parameters are given.Based on the magnetic circuit model,the mathematical expressions of the axial magnetic force of the conical motor are also given.On this basis,the influence mechanism of cone angle and dq-axis currents on axial magnetic force was analyzed,providing a theoretical basis for the study of axial magnetic force in conical permanent magnet synchronous motors.
