High-speed atomizer based on magnetic suspension bearing permanent magnet synchronous motor

Abstract

The invention relates to a high-speed atomizer based on a magnetic suspension bearing permanent magnet synchronous motor. The high-speed atomizer comprises a permanent magnet synchronous motor, a loading and distributing mechanism of the atomizer and an atomizing wheel, wherein the permanent magnet synchronous motor is integrated with a high-frequency power supply; a magnetic suspension radial bearing and a magnetic suspension axial bearing are arranged in the permanent magnet synchronous motor to provide radial and axial support for a motor shaft; the extending-out end of the motor shaft is sequentially provided with the loading and distributing mechanism of the atomizer and the atomizing wheel in a sleeving mode; and the loading and distributing mechanism of the atomizer is composed of a distributor and a feeding tube. The high-speed atomizer adopts the permanent magnet synchronous high-speed motor which is integrated with a large-power high-frequency power supply and magnetic suspension bearings to directly drive the atomizing wheel, so that speed regulation range for the rotation speed of a rotor is large; when rotating at a high speed, a rotor shaft is completely supported by the magnetic suspension bearings, and is not in direct contact with other parts, so that lubricating is not required, and therefore, the problems of easy abrasion, a short service life, high operation cost and the like of a current atomizer are completely solved.

Description

technical field [0001] The invention relates to an atomizer, in particular to a high-speed atomizer based on a magnetic suspension bearing permanent magnet synchronous motor. Background technique [0002] Such as figure 1 As shown, the currently commonly used rotary atomizer is generally composed of an atomizing wheel 1, a feeding and distributing mechanism 2, a transmission shaft 3, a machine base 4, a speed-up gearbox 5, a coupling 6, a motor 7 and a frequency converter 8 In addition, oil supply and cooling systems need to be configured, which have the following problems in use: [0003] 1) The structure of the equipment is complex and there are many failure points. Due to the high-speed rotation, the core mechanical parts such as transmission and speed increase are very easy to wear, resulting in short life and high maintenance costs; [0004] 2) Lubricating oil is required for both the gearbox and the main shaft components, and it rotates at a high speed (more than 10,...

Problems solved by technology

[0008] The invention provides a high-speed atomizer based on a permanent magnet synchronous motor with a magnetic suspension bearing. The permanent magnet synchronous high-speed motor integrating a high-power high-frequency power supply and a magnetic suspension bearing is used to directly drive the atomization wheel. The rotor speed adjustment range is large. Moreover, the rotor shaft is completely supported by the magnetic suspension bearing when it rotates at high speed, and does not directly contact with other parts, so no lubrication is required; it completely solves the problems of easy wear, short life and high operating cost of the existing atomizer
