Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, the multi-phase nested winding type permanent magnet synchronous planar motor described in this embodiment includes a permanent magnet excitation part 1 and an orthogonal nested armature winding part 2, both of which are planar structures with an air gap in the middle ; In the planar motor, the permanent magnet excitation part 1 is the mover, and the armature winding part 2 is the stator. The side length and the number of poles of the stator are larger than the mover, and the difference between the side length and the number of poles of the two determines the driving range of the planar motor. The permanent magnet excitation part 1 includes two parts: a two-dimensional permanent magnet array 1-1 and a yoke 1-2. The two-dimensional permanent magnet array 1-1 is pasted on the surface of the yoke 1-2 near the winding side; the armature The winding 2 includes two sets of windings, one set is the winding 2-1 placed along the X direc...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that in the multi-phase nested winding type permanent magnet synchronous planar motor, the permanent magnet excitation part 1 is the stator, and the armature winding part 2 is the mover. The structure of the armature winding 2 is relatively simple, eliminating the need for a thyristor structure. The winding 2-1 placed in the X direction and the winding 2-2 placed in the Y direction are directly divided into 4 parts with the center line of the Y direction and the X direction as the dividing line; the number of poles in each part is 2n, where n is an integer , the total number of poles of all windings is 8n; the same-phase windings in each part are connected to each other.

Embodiment 3

[0044] The difference between this embodiment and Embodiments 1-2 is: as Image 6 As shown, the magnetization direction of the auxiliary magnetic pole 1-1-1-2 at the side of the N-pole excitation module and the auxiliary magnetic pole 1-1-2-2 at the side of the S-pole excitation module are magnetized in parallel It becomes magnetized in the diagonal direction. The auxiliary magnetic pole 1-1-1-2 on the side of the N-pole excitation module is magnetized in the direction from the winding side close to the central part to the yoke side close to the outside, and at the same time contains the direction from the S pole to the N pole and the vertical The magnetic field component facing outward from the plane of the yoke; the magnetization direction of the auxiliary magnetic pole 1-1-2-2 on the side of the S-pole excitation module is the same as that of the auxiliary magnetic pole 1-1-1-2 on the side of the N-pole excitation module. 2 On the contrary, from the side near the outer sid...

Abstract

The invention discloses a multi-phase nested winding type permanent magnet synchronous planar motor. It includes the permanent magnet excitation part and the armature winding part. After the two parts are superimposed, there is an air gap; the permanent magnet excitation part includes a two-dimensional permanent magnet array and a yoke composed of N pole and S pole excitation modules. The excitation modules have the same size. And all include a vertically excited main magnetic pole at the center, auxiliary magnetic poles at four sides and auxiliary magnetic poles at four corners; the armature winding includes windings placed along the X direction and along the Y direction, along X and along Y The windings placed in each direction are divided into two parts based on the Y-direction and X-direction centerlines. The windings between the four parts are independent of each other. According to the relative position between the armature winding and the two-dimensional permanent magnet array, the current of each part of the winding can be controlled. Separate control to realize driving and positioning of five degrees of freedom. The invention has the advantages of high winding utilization rate, light weight, fast response speed, wide range of movement, etc., and can be used in the occasions requiring multi-degree-of-freedom driving and positioning.
