specific Embodiment 1

[0043] Such as Figure 1 to Figure 6 As shown, the frameless magnetic bearing stator includes a stator ring 8, an iron core 9, and a coil 1. The iron core 9 is arranged on the stator ring 8, and the coil 1 is located on the periphery of the iron core 9; there is a paper tube 2 between the coil 1 and the iron core 9. , the coil 1 is wound on the paper tube 2, and the paper tube can maintain the shape of the coil and is not easy to disperse. In order to facilitate the installation of the coil 1, reduce the deformation of the coil 1, and reduce the scratching of the coil 1 during installation, both ends of the paper tube 2 have protective strips 3 that extend out of the coil 1 and are folded outward to meet the end surface of the coil 1. The protective strip 3 is folded from the end surface of the coil 1 to the outer peripheral surface of the coil 1 and pasted on the outer peripheral surface of the coil 1 . The protective strip 3 is L-shaped, one of the two folded edges is attac...

Abstract

The invention relates to a frameless magnetic bearing stator and a coil winding tool and method thereof. The frameless magnetic bearing comprises a stator ring and an iron core, wherein the iron core is arranged on the stator ring; the coil is positioned outside the iron core; the paper tube is located between the coil and the iron core, and the coil is wound on the paper tube; and the two ends of the paper tube are provided with protective strips which extend out of the coil and are folded outwards to be attached to the end face of the coil. According to the frameless magnetic bearing, the stator coil is wound on the paper tube, the protection strips at the two ends of the paper tube can protect the coil, the paper tube is adopted to replace a framework in the prior art, the cost of the magnetic bearing is reduced, and the technical problem that in the prior art, the manufacturing cost is high due to the fact that the coil is wound through a framework body is solved.

Description

technical field [0001] The invention relates to a frameless magnetic bearing stator and its coil winding tooling and winding method. Background technique [0002] Magnetic suspension bearings are magnetic bearings, which use magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. Magnetic bearing rotors can run at higher speeds with less mechanical wear and a longer life than conventional bearings. [0003] The stator of the magnetic bearing includes a stator ring, an iron core and a coil, wherein a plurality of iron cores are arranged along the circumference of the stator ring, and a plurality of iron cores surround the outer periphery of the rotor. Due to the small size of the inner hole of the stator ring, the size of the coil is as small as possible. At present, the coil is wound directly on the iron core. Due to the small operating space, the winding efficiency of the coil is low. [0004] The Chinese pa...
