Permanent magnet rotor driving type multi-degree-of-freedom motion motor

Abstract

The invention provides a permanent magnet rotor driving type multi-degree-of-freedom motion motor, and relates to the technical field of multi-degree-of-freedom motors. A rotor comprises a fixed shaft. The upper end of the fixed shaft of the rotor is fixedly connected with an inner ring of a bearing. Meanwhile, the rotor is connected with the bottom end of an upper output shaft through an oil film. An outer ring of the bearing is fixedly connected with the output shaft. The outer ring is fixedly provided with a rotor frame. A plurality of permanent magnet yokes and rotor permanent magnets arearranged around the rotor frame. A stator is located on the periphery of the rotating part of the rotor. The stator comprises a plurality of left semicircular cylinders and corresponding right semicircular cylinders. Stator coil yokes are distributed on the inner side of the stator. The rotor of the motor can do multi-degree-of-freedom motion by introducing different power-on strategies into a plurality of stator coils. The problems that a traditional multi-degree-of-freedom motor is large in size, complex in structure, low in precision, low in efficiency and the like are mainly solved. The multi-degree-of-freedom motion of the motor can be realized by applying different power-on strategies. The multi-degree-of-freedom motor has the advantages of simple and compact structure, small size, accurate control, convenient use, wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom motors. Background technique [0002] With the advancement of social economy and technology, in order to achieve higher and more rigorous and precise motion, not only the motor is required to achieve self-rotation, but also a certain degree of inclination of the motor is required in some fields. The traditional motor has a single degree of freedom, and through multiple single degrees of freedom The interconnection of the system is not only bulky but also complex in structure, low in efficiency and low in economic benefits, and many high-tech fields such as bionic robots, aerospace, manipulators and other fields urgently need motors with higher precision and less loss to complete the motion. [0003] As a modern research field, multi-degree-of-freedom motors have broad prospects. The research on multi-degree-of-freedom motors can be traced back to the 1950s. Due to the lack of theor...
