Abstract

The invention relates to a linear rotation two-degree-of-freedom motor. The linear rotation two-degree-of-freedom motor comprises a base, a main shaft, a first driving part and a second driving part; the first driving part comprises a first iron core arranged in the base and a first winding wound on the first iron core, and the winding direction of the first winding is perpendicular to the axis of the main shaft; the second driving part comprises a second iron core arranged in the base and a second winding wound on the second iron core, and the winding direction of the second winding is parallel to the axis of the main shaft; the main shaft penetrates through the base, the two ends of the main shaft extend out of the two ends of the base, magnetic induction lines of the first driving part and the second driving part penetrate through the main shaft, and the distance between the first winding and the main shaft is equal to the distance between the second winding and the main shaft. According to the linear rotation two-degree-of-freedom motor, the first driving part and the second driving part are arranged to directly drive the main shaft to move, and at the moment, the sizes of the first driving part and the second driving part can be reduced, so that the overall size of the linear rotation two-degree-of-freedom motor is reduced, and the linear rotation two-degree-of-freedom motor is more convenient to install and use.

Description

technical field

[0001] The present application relates to the technical field of motors, in particular to a linear rotation two-degree-of-freedom motor. Background technique

[0002] As the complexity of industrial drive systems increases and the drive precision requirements increase, the application of two-degree-of-freedom drives is becoming more and more extensive. The current two-degree-of-freedom drive is usually realized through a combined structure, that is, by setting a first driving member that drives the main shaft to move linearly, and then setting a second driving member that drives the first driving member to rotate along the axis of the main shaft, so as to realize The driven main shaft can not only rotate along its axis, but also move along its axis.

[0003] In view of the related technologies mentioned above, the inventor believes that although the two-degree-of-freedom drive can be realized in a combined manner, the overall volume is relatively large, so t...
