Magnetic suspension bearing lead structure and forming method thereof, magnetic suspension bearing and motor

Abstract

The invention provides a magnetic suspension bearing lead structure and a forming method thereof, a magnetic suspension bearing and a motor. The magnetic suspension bearing lead structure comprises awiring board (2), a stator iron core (1) and a stator winding arranged on the stator iron core (1), wherein the stator winding comprises a plurality of coil joints, each coil joint is correspondinglyprovided with a binding post (3), the wiring board (2) comprises wiring plugs (4) and outgoing line joints (5), the wiring plugs (4) and the binding posts (3) are in one-to-one correspondence plug-inconnection, and wiring terminals of the wiring plugs (4) and the outgoing line joints (5) are in one-to-one correspondence connection through wires. According to the magnetic suspension bearing lead structure, the wiring mode of the magnetic suspension bearing can be simplified, and the electrical safety of the wiring connection part of the magnetic suspension bearing is improved.

Description

technical field [0001] The application relates to the technical field of electric motors, in particular to a magnetic suspension bearing lead wire structure and a forming method thereof, a magnetic suspension bearing and a motor. Background technique [0002] Magnetic suspension bearings have a series of excellent qualities such as no contact, no wear, high speed, high precision, no need for lubrication and sealing, and are a high-tech product integrating electromagnetics, electronic technology, control engineering, signal processing, and mechanics. [0003] Magnetic suspension bearings are divided into three types: active, passive, and hybrid. Active magnetic suspension bearings have high rigidity and can be precisely controlled, but require a large volume and power consumption to generate unit bearing capacity; passive magnetic suspension bearings use the attraction between magnetic materials Or repulsion realizes the suspension of the rotor, and the stiffness and damping ...

AI Technical Summary

Problems solved by technology

[0004] Because the magnetic suspension bearing has a winding coil, after winding the wire, it is necessary to lead out the enameled wire end. Since the enameled wire itself has a thin insulating layer, generally the enameled wire will not be led out directly, and a wire with an insulating layer will be connected to the end of the enameled wire as the lead out. The interface is welded with solder, and then the insulation protection is done on the surface. The operation process of this wiring method is complicated, and there is a risk of poor insulation after the surface insulation layer is scratched or broken.
