Embodiment Construction

[0021] The present invention will be further elaborated below through specific embodiments.

[0022] like figure 1 As shown, a linear rotation two-degree-of-freedom permanent magnet motor includes a stator and a mover, which can realize linear, rotary, and helical motions. The stator is composed of m stator units arranged in the axial direction, and the stator units are arranged in pairs. A stator magnetic isolation ring 3-2 is arranged between them, and the stator unit is composed of n stator tooth modules arranged along the circumferential direction, and the stator tooth 1 is a double harpoon overlapping structure.

[0023] like Figure 4 As shown, the overlapping and connecting part of the double harpoon is a slightly arched bridge-shaped ridge with a smooth radian; the axial section of the ridge is rectangular, and the circumferential section is a small ring. The bottom of the double harpoon is close to the mover. Compatible ring substrate.

Abstract

The invention discloses a linear rotation two-degrees-of-freedom permanent magnet motor, which comprises a stator and a mover, and is characterized in that the stator is formed by arranging stator units in the axial direction, a stator magnetic isolation ring is arranged between every two stator units, and each stator unit is formed by arranging a plurality of stator tooth modules in a circumferential direction; each stator tooth module is provided with windings, and the windings are respectively a linear winding and a rotating winding; and the mover is composed of a mover yoke and a permanentmagnet block, and the permanent magnet block is arranged on the surface of the mover yoke. The linear rotation two-degrees-of-freedom permanent magnet motor adopts a unique stator tooth structure andtwo sets of armature windings, realizes linear, rotary and spiral motions of the motor, has the advantages of small stator eddy current loss, high output torque and high thrust, and is easy to process and manufacture.

Description

technical field [0001] The invention relates to a linear rotation two-degree-of-freedom permanent magnet motor, which is suitable for applications requiring linear, rotary and helical motion drives, and belongs to the technical field of special motors. Background technique [0002] With the increase in the complexity of industrial drive systems and the increase in drive accuracy requirements, the application of two-degree-of-freedom drives is becoming more and more extensive, such as human joints, robotic arms, high-end machine tools, ship propulsion, artillery turntables, multi-coordinate machining, and satellite tracking. Antennas, electric gyroscopes, etc., especially some precision devices, have increasingly urgent requirements for two-degree-of-freedom drives. One-dimensional motion single-degree-of-freedom motors cannot meet the driving requirements, and a large number of two-dimensional motion motors and their driving mechanisms are required. [0003] The linear rotat...
