Problems solved by technology

The current mainstream spherical motor still adopts the structure with an output shaft, and its multi-degree-of-freedom realization is mainly reflected in the main motion of rotating around the output rotation axis and the auxiliary motion of offsetting a certain angle with the output shaft, and its essence has not yet got rid of the traditional There is an output shaft form, the realization of multi-degree-of-freedom motion is based on the main motion, and there is an angular range limit

Abstract

The invention discloses a spherical induction motor without an output shaft. The induction motor includes a spherical shell, a stator support and stator units fixed on the stator support; the stator units are located between the stator support and the spherical shell; bull-eye bearings are arranged between the stator support and the spherical shell, and include arctic bearings and weft ring bearing sets, and / or Antarctic bearings; all the bull-eye bearings are in contact with the spherical shell; the stator support includes longitude rings arranged in a longitude direction and weft rings arranged in a weft direction; the weft ring bearing sets include multiple bull-eye bearings fixed on the same weft rings; each stator unit is at an included angle with longitudes; and the centers of gravity of the stator units are located on the same weft and below the equator of the stator support. The induction motor is simple in structure and control without extra power transmission equipment; and the induction motor can be applied to direct driving occasions of robot driving, detection device driving and spherical cameras.

Description

technical field [0001] The invention relates to the field of induction motors, in particular to a spherical induction motor without an output shaft. Background technique [0002] In the field of modern industry, especially in the field of robot technology and intelligent control technology, people have higher requirements for the accuracy, flexibility and economy of drive motors, and the motor industry is also developing continuously. Various new micro motors and Its drive control method is also constantly innovating to adapt to more and more applications. [0003] At present, the mainstream motors used as power supply devices often only have a single degree of freedom, that is, an output shaft, and can only output torque in one direction to the outside. Multiple motors are used to drive together to provide multi-degree-of-freedom power. This method not only makes the entire power system have numerous modules, but also has a large volume, high cost, and difficult manufactur...
