Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0022] Such as Figure 1 to Figure 4 As shown, a new three-degree-of-freedom planar induction motor includes a linear drive unit 3 with three stators 2 arranged in a "Y" shape, and a rotary drive unit 4 with three stators 2 arranged in a "△" shape. Cylindrical base 1, bearing 6 and disc-shaped mover 5.

[0023] The drive unit of the induction motor is as image 3 , Figure 4 and Figure 6 As shown, the linear drive unit 3 and the rotary drive unit 4 are both arranged on the base 1 .

[0024] Such as Figure 5 As shown, the bottom surface of the stator 2 is rectangular, and the line connecting the midpoints of the wide sides of the bottom surface is defined as the stator axis 9 .

[0025] The linear drive unit 3 is composed of three stators 2 which are evenly distributed in space around the center of the base 1 . The stator axes 9 of the three stators 2 all pass t...

Abstract

The invention discloses a three degree of freedom plane induction motor. The three degree of freedom plane induction motor comprises a linear drive unit arranged in a Y type arrangement, a rotary drive unit arranged in a triangle-shaped arrangement, a disk-shaped mover, and a cylindrical base. The three degree of freedom plane induction motor can achieve a multi-degree of freedom movement of straight line, rotation and in-plane spiral. The linear drive unit is used for realizing linear motion in any direction in the plane, and the rotary drive unit is used for realizing the rotational motion. When the two groups of drive units work at the same time, the in-plane spiral movement can be achieved . The three degree of freedom plane induction motor has the characteristics of simple structure, good dynamic performance, few components, easy maintenance, small mover mass, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a multi-degree-of-freedom planar induction motor. Background technique [0002] The driving motors of flexible manufacturing systems, CNC machine tools, robots and other devices usually need to complete multi-degree-of-freedom movements. The transmission is realized by mechanically connecting multiple single-degree-of-freedom motors through an intermediate transmission mechanism to complete multi-degree-of-freedom movements. However, this method brings some inevitable problems, such as [0003] Large volume and mass, large maintenance, expensive, poor dynamic response performance. [0004] Chinese patent CN1996726A discloses "an ultra-thin 3-DOF planar motor" which realizes multi-DOF motion by controlling multiple sets of driving coils, simplifies the transmission mechanism of the motor, but still has many parts and requires a large amount of maintenance. [0005] The "...
