Example Embodiment

[0035] The accompanying drawings are only used to illustrate examples, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, some components in the accompanying drawings may be omitted, enlarged or reduced. Omissions, enlargements or reductions where present are understandable. Below in conjunction with accompanying drawing, this patent is described in detail.

[0036] As a specific embodiment of the present invention, the technical solution adopted by the present invention is: a hybrid drive type multi-stator multi-degree-of-freedom motor, including a housing 4, characterized in that it includes a stator and a rotor; the stator includes a circular cylindrical stator 11 and a telescopic stator 12. The annular cylindrical stator 11 is divided into upper and lower layers; separated in the middle (the two-layer stator will make the motor have better deflection performance); there are several pole shoes and stator windings 13 dis...

Abstract

The invention provides a hybrid-driven multi-stator multi-degree-of-freedom motor, which relates to the technical field of multi-degree-of-freedom motors. A rotor is arranged in a circular cylindricalstator. The rotor includes a rotor frame, and an output shaft is fixed on the rotor frame. A number of permanent magnets are attached to the surface of the outer edge of the rotor frame, and a numberof cylindrical permanent magnets are arranged on the circumference. A fixed shaft and the output shaft are connected by a ball structure. A sensor for detecting the position and speed of the rotor isarranged in the fixed shaft. The lower part of the fixed shaft is connected with a supporting material, which realizes scalability and has certain stiffness. Telescopic stators are respectively arranged above and below the rotor. Driving coils are distributed on the telescopic stators, and the positions and number of the driving coils correspond to those of the cylindrical permanent magnets. Theinvention mainly aims to solve the problem that the traditional multi-degree-of-freedom motor has the disadvantages of huge size, low precision, low efficiency, low degree of freedom and complex control. The hybrid-driven multi-stator multi-degree-of-freedom motor of the invention has the characteristics of simple structure, small size, many degrees of freedom, fast response, simple, accurate anddiverse control, low loss and wide use.

Description

technical field [0001] The invention relates to the technical field of multi-degree-of-freedom motors. Background technique [0002] With the advancement of science and technology and the development of some new fields, the requirements for motor precision, motor degrees of freedom, and motor volume are getting higher and higher. There are also more stringent requirements, not only requiring that the motor can complete a certain intensity of motion, but also have more stringent restrictions on volume and loss, and the traditional multi-degree-of-freedom motor is difficult to complete the required indicators, so for more Fine and accurate multi-degree-of-freedom motor research is very important. [0003] As a new research field in modern times, multi-degree-of-freedom motor has very broad prospects and research potential. With the in-depth research on multi-degree-of-freedom motors, so far, the theory of multi-degree-of-freedom motors has gradually become full, and many new...
