Abstract

A flywheel energy storage device, a magnetic bearing and an eddy current sensor assembly thereof, the assembly includes: four eddy current sensors; a first fixing base; a second fixing base; and a circuit board; wherein, the first fixing base, the circuit The plate and the second fixing seat have a central hole, and the four eddy current sensors are arranged symmetrically on the first fixing seat, and the detection end of each eddy current sensor faces the central hole of the first fixing seat, and the position Two opposite eddy current sensors cooperate to realize a differential measurement, the first fixing base is fixed on the second fixing base, and the circuit board is sandwiched between the first fixing base and the second fixing base. The invention is suitable for occasions requiring high space and has high measurement accuracy.

Description

technical field [0001] The invention relates to a magnetic bearing, in particular to an eddy current sensor assembly suitable for the magnetic bearing. Background technique [0002] The eddy current sensor can measure the distance between the metal conductor under test and the surface of the probe with non-contact, high linearity and high resolution, both statically and dynamically. It is a non-contact linear measurement tool, which can accurately measure the static and dynamic relative displacement changes between the metal conductor material and the probe end face. The eddy current sensor assembly consists of two parts, the stator and the rotor. The rotor is fixed with the rotating shaft, and the stator is fixed on the casing. The rotor is suspended in the center of the stator through control. The eddy current sensor is used to detect the radial offset of the rotor, which is fed back to the control circuit of the eddy current sensor assembly. The fixing method of the exi...
