摘要
针对螺旋桨轴向力磨损电推进电机轴承问题,本文提出一种锥形电推进电机方案,利用锥形电机的轴向力平衡螺旋桨的轴向力.首先,建立了电推进锥形永磁同步电机磁路模型,给出了相关参数的数学解析式,同时基于磁路模型给出了锥形电机轴向磁拉力的数学表达式.其次,在此基础上分析了锥角及交直轴电流对轴向磁拉力的影响机理,为锥形永磁同步电机轴向磁拉力的研究提供了理论参考.
Abstract
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.
