Title:
ELECTRIC VALVE CONTROL DEVICE AND ELECTRIC VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238645
Kind Code:
A1
Abstract:
[Problem] To provide an electric valve control device and an electric valve device which can relatively easily detect that the rotation of a magnet rotor has been regulated. [Solution] This electric valve control device controls an electric valve. The electric valve has a first magnetic sensor 91 and a second magnetic sensor 92. Output signals of the first magnetic sensor 91 and second magnetic sensor 92 are binary signals. When the total number of a plurality of N-poles and a plurality of S-poles of the magnet rotor 31 is noted as n, a natural number is denoted as N, an angle between a line M1 connecting an axis line L and the first magnetic sensor 91 and a line M2 connecting an axis line L and the second magnetic sensor 92 is denoted as θ, the following equation (1) is satisfied. (1) θ=(360/n)×N＋(360/2n)
The electric valve control device detects the regulation of rotation of the magnet rotor 31 on the basis of the output signals and expectation value information about the output signals.
