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

Abstract

The invention provides a permanent-magnet rotor deflection-type three-degree-of-freedom motion motor, which relates to the technical field of permanent-magnet rotor motors. The motion motor is characterized in that magnetism isolating sheets and permanent magnets consisted of non-magnetic-conduction materials are distributed on the outer side of the inner core of the rotor. N-poles and S-poles are distributed in a staggered way and the outlines of the permanent magnets are spherical. At least two layers of magnetic pole iron cores are provided on the rotor of the periphery. Stator magnetic pole loops are provided on the magnetic pole iron cores. An output shaft is rigidly connected with center of the stator, the center of an outer housing overlaps with center of the rotor and the rotor is supported by a circular ball bearing fixed on the stator. The stator is provided with a transducer for detecting the position and the speed of the rotor so as to realize closed-loop control of the motor. The motion motor of the invention solves the problems of the three-degree-of-freedom motion motor in the prior art, including heavy abrasion, poor torque output capacity and the like. The motion motor of the invention is relatively simple in structure, easy to control, high in mechanical integration level, small in abrasion, strong in torque output capacity, and excellent in static and dynamic performance. In addition, the motion motor can realize suspension control.

Description

[0001] technical field [0002] The invention relates to the technical field of permanent magnet rotor motors. Background technique [0003] 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. [0004] 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.
