Abstract

The invention relates to the technical field of magnetic suspension, in particular to a magnetic bearing assembly preparing technology. A magnetic bearing assembly comprises a permanent magnet biasedradial magnetic bearing, a sensor support and sensor probes. The permanent magnet biased radial magnetic bearing comprises a first magnetizer and a second magnetizer which are arranged in parallel. Aplurality of first magnetic poles are arranged in the first magnetizer, and an exciting coil is wound around each first magnetic pole. A permanent magnet is arranged between the adjacent two layers ofmagnetizers. The sensor support comprises an annular fixing plate, and a plurality of installing grooves are formed in the inner circle of the fixing plate and used for installing the sensor probes.The first magnetizer and the second magnetizer are arranged on the two sides of the fixing plate correspondingly. The preparing technology comprises the steps that firstly, the sensor probes are placed in the installing grooves; secondly, the first magnetizer and the second magnetizer are fixed to the two sides of the fixing plate correspondingly and are connected through the permanent magnet; andthirdly, the magnetic bearing assembly assembled in the second step is subjected to plastic package through a glue filling plastic package technology. Integral connection is more reliable.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension, in particular to a preparation process of a magnetic bearing assembly. Background technique [0002] Magnetic Bearing (Magnetic Bearing) uses magnetic force to suspend the rotor in the air, so that there is no mechanical contact between the rotor and the stator. The principle is to form a closed loop between the stator and rotor after the stator coil winding is energized. The magnetic line of force enters the rotor through the stator magnetic poles, and forms an electromagnetic force on the rotor surface to adsorb the rotor. Using the balance of the adsorption force of each magnetic pole on the rotor circumferential surface, the rotor is suspended in the stator-rotor air gap, and the non-contact between the stator and rotor is realized. Therefore, the rotor The weight of the rotor is fixed on the running track, and the almost no-load shaft core is used to support the direction of the...
