Calculation and Analysis of Drive Torque of Axial Magnetic Drive Mechanism

The magnetic circuit parameter design problem was proposed aiming at axial magnetic drive mechanism driving torque. Analyzed axial magnetic drive mechanism driving principle .According to the mathematics model of the magnetic coupling torque that was established based on the equivalent magnetic charge theory, analyzed magnetic circuit design, included material selection, magnetic circuit type, the working air gap of magnetic circuit, magnet and the thickness of the magnets and resistive magnets. The basis was provided for the rational design of high-performance axial magnetic drive mechanism.
