Abstract

The invention provides a dual-stator multi-degree-of-freedom motor, which relates to the technical field of multi-degree-of-freedom motors. A rotor is located between an outer stator and an inner stator. A magnetic isolation plate is embedded between the inner and outer sides of the rotor. Windings are arranged on the inner sides of the outer stator and the rotor and on the toothed poles of the inner rotor respectively, and permanent magnets or toothed poles are arranged on the outer side of the rotor. The inner side of the outer stator, the outer and inner sides of the rotor and the outer sides of the toothed poles of the inner stator are spherical in shape. The lower end of the shaft of the rotor is connected with the connecting shaft of the inner stator through a joint bearing. The rotor is fixed to the upper part of the output shaft through a rotor connecting plate. The length of the rotor shaft is at the upper opening position of the outer stator and the inner stator, and the rotor shaft can rotate and deflect. The invention mainly aims to solve the problem that the existing multi-degree-of-freedom motor has small output torque. The dual-stator multi-degree-of-freedom motor can realize coordinated control of rotation and deflection, has the characteristics of large output torque, simple and compact structure, small occupied space and low cost, and can be applied to the field of driving devices requiring multi-degree-of-freedom motion in space.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom motors. Background technique [0002] With the continuous development of modern industrial level and science and technology, people's requirements for the stability and accuracy of industrial devices are also increasing. Traditional multi-degree-of-freedom motion system devices are usually composed of multiple single-degree-of-freedom drive devices and mechanical transmission devices. This complex structure increases the volume and cost of the system, reduces the reliability of the system, and causes greater friction loss. The multi-degree-of-freedom motor has high mechanical integration, simple transmission, simplifies the system mechanism, improves operating efficiency, and has a broad development space. In the fields of aerospace, home appliances, robotic arms, bionics and demanding precision, the demand for multi-degree-of-freedom motors is getting higher and higher. [0003]...
