Permanent-magnet rotor deflection-type three-degree-of-freedom motion motor

Abstract

The invention discloses a permanent magnet rotor deflection type three-degree-of-freedom motion motor, which relates to the technical field of permanent magnet rotor motors. It is characterized in that magnetic spacers and permanent magnets made of non-magnetic materials are distributed outside the inner core of the rotor, N poles and S poles are alternately distributed, and the shape of the permanent magnets is an outer spherical shape; there are at least two layers of magnetic poles on the outer stator Iron core, magnetic pole iron core is provided with stator magnetic pole coils, the output shaft is fixedly connected with the center of the rotor, the center of the casing coincides with the center of the rotor, and the rotor is supported by a ring-shaped ball bearing fixed on the stator; the stator is equipped with a detection rotor position With the speed sensor, through the corresponding detection circuit, the closed-loop control of the motor is realized. The invention solves the problems of large wear and poor torque output ability of the existing three-degree-of-freedom motion motor, and has a relatively simple structure, easy control, high mechanical integration, small wear, strong torque output ability, good static and dynamic performance, and can Achieve suspension control.

Description

technical field [0001] The invention relates to the technical field of permanent magnet rotor motors. Background technique [0002] The traditional method of realizing multi-degree-of-freedom motion is to use multiple single-degree-of-freedom motors with mechanical transmission devices, which easily leads to a decrease in accuracy and efficiency, and is often bulky and expensive. Using multi-degree-of-freedom motors, especially three-degree-of-freedom motors to achieve complex movements is an ideal solution at present. This type of motor is widely used in robot joints, omni-directional drive hubs, panoramic camera platforms, space measurement, multi-directional transmission structures, etc. field. [0003] The multi-degree-of-freedom motor with permanent magnets can greatly increase the magnetic energy product of the motor, effectively improve the operating efficiency of the motor, reduce the volume of the motor, and improve the controllability of the motor. The developmen...
