Document Type and Number:
WIPO Patent Application WO/2023/276366
Kind Code:
A1
Abstract:
[Problem] To provide an electric valve that has a small vertical dimension and is capable of accurately detecting the rotation angle of a magnet rotor. [Solution] The electric valve (1) has a permanent magnet (45) that is disposed coaxially with a magnet rotor (41) inside of a can (30). The permanent magnet (45) has a circular outer shape, and rotates with the magnet rotor (41). One N pole is disposed in a first section (45n) and one S pole is disposed in a second section (45s), said sections being demarcated by the diameter of the permanent magnet (45). The magnetization direction of the permanent magnet (45) is orthogonal to the axis (L). An angle sensor (96) that detects the rotation angle of the permanent magnet (45) is aligned with the can (30) in a direction orthogonal to the axis (L).
