Bridge arc-shaped stators of the rotary motion linear arc-shaped motor and the rectilinear motion linear arc-shaped motor are integrated into a whole by fasteners and step-shaped structures, stator core laminations are distributed in space in an orthogonal manner, stator windings are arranged in an orthogonal and zoning manner, a cylindrical rotor is shared by the two motors, and stator core zone areas and structural parameters thereof can be respectively selected for the two linear arc-shaped motors according to performance indexes. By adopting the scheme in the invention, a load can be directly driven to do linear, rotary or spiral motion, and the multivariant linear arc-shaped motor has the advantages of simple and compact structure, concise transmission mechanism, small bearing wear, easy control and the like.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom linear arc motor, which has a rotary motion linear arc motor for driving a rotating shaft to rotate and a linear arc motor for driving the rotating shaft to move axially and linearly, and is especially suitable for driving a load to perform spiral motion. Background technique [0002] The drive motors of devices such as flexible manufacturing systems, robots, and precision CNC machine tools need to achieve rotary motion or linear motion on the drive shaft. These movements can occur independently or simultaneously. Traditional technologies realize rotary or linear motion units through mechanical combination. These solutions not only have quite complicated control methods, but also require many expensive, bulky and cumbersome mechanical transmission devices. In addition, transmission components and bearings absorb high axial forces, resulting in considerable mechanical wear of these components. [0003...

AI Technical Summary

Problems solved by technology

The stator windings of the rotating motor and the linear motor of the device are arranged on a pot-shaped outer rotor, and the outer rotor directly drives the output shaft. The moment of inertia is large, the bearing wear is relatively large, the mechanical structure is complicated, and the processing cost is high. big structure

[0005] Both of the above two patents use the combination of rotary motor and linear motor, and realize the rotation or linear motion of the load through the auxiliary transmission mechanism, but both have complex structures, Serious bearing wear, complicated mechanical structure, etc.
