Abstract

The invention discloses a flywheel energy storage device, a magnetic bearing and an eddy current sensor assembly of the magnetic bearing. The eddy current sensor assembly comprises four eddy current sensors, a first fixing seat, a second fixing seat and a circuit board; the first fixing seat, the circuit board and the second fixing seat are provided with central holes, the four eddy current sensors are symmetrically distributed on the first fixing seat, the detection end of each eddy current sensor faces the central hole of the first fixing seat, the two eddy current sensors which are oppositein position are matched to realize one-way differential measurement, the first fixing seat is fixed on the second fixing seat, and the circuit board is clamped between the first fixing seat and the second fixing seat. The flywheel energy storage device, the magnetic bearing and the eddy current sensor assembly of the magnetic bearing are suitable for occasions with high space requirements and have high measurement precision.

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...
