Abstract

The invention provides a stator assembly, a magnetic suspension bearing and a compressor. The stator assembly comprises a stator iron core (1) and frameworks (2), the stator iron core (1) comprises stator teeth (3) and stator grooves (4), the stator frameworks (2) comprise insulation yoke parts (5) and insulation tooth parts (6), the insulation yoke parts (5) are connected with the insulation tooth parts (6), the insulation tooth parts (6) wrap the stator teeth (3), the insulation tooth parts (6) comprise tooth grooves for installing the stator teeth (3), and at least one stator framework (2) is provided with a first cooling flow channel (7). An inlet flow channel (8) is arranged at the end, far away from the first cooling flow channel (7), of each stator framework (2), wherein the inlet flow channel (8) is communicated with the first cooling flow channel (7), and the first cooling flow channel (7) is communicated to a central hole of the stator iron core (1). According to the stator assembly, a rotor of the magnetic suspension bearing can be effectively cooled, and the operation reliability of the magnetic suspension bearing is improved.

Description

technical field [0001] The present application relates to the technical field of magnetic suspension, in particular to a stator assembly, a magnetic suspension bearing and a compressor. Background technique [0002] Magnetic suspension bearing is a kind of bearing that uses electromagnetic force to support the stable suspension operation of the rotor system. Compared with traditional mechanical bearings, magnetic suspension bearings have excellent characteristics such as no friction, no wear, no lubrication, high operating speed, long life and low maintenance costs. The field has broad application prospects. [0003] The magnetic levitation rotor runs at a high speed. Due to the existence of the electromagnetic field, the magnetic levitation rotor will cut the magnetic induction line in the electromagnetic field, resulting in a large eddy current loss on the rotor. In addition, the friction between the high-speed rotating magnetic levitation rotor and the air will also cau...
