Magnetic bearing-rotor system multifunctional experiment table

Abstract

The invention provides a magnetic bearing-rotor system multifunctional experiment table which mainly comprises a base, a motor, a radial magnetic bearing, a radial displacement sensor, an axial displacement sensor, an axial thrust magnetic bearing, an axis trajectory sensor, an auxiliary bearing, a rotor, a disc, a thrust collar, a scale and housings. A motor stator, the radial magnetic bearing, the radial displacement sensor, the axial displacement sensor, the axial thrust magnetic bearing and the auxiliary bearing are mounted in different housings. All housings can be fixed on the base through a V-shaped trough and can randomly slide in the V-shaped trough. Position locking of the housing is realized through a T-shaped trough nut and a bolt. The disc and the thrust collar are mounted onthe rotor. The rotor can realize 6-freedom stable suspension and is driven by the motor to rotate. The axis trajectory sensor can randomly slide on the base. The magnetic bearing-rotor system multifunctional experiment table has remarkable advantages of modularization, integration, multiple functions, convenient mounting and testing, multi-point supporting, random sliding, cross-critical rotatingspeed, and capability of mounting the rotor to multiple discs.
