Title:
MOTOR VALVE
Document Type and Number:
Japanese Patent JP2023090763
Kind Code:
A
Abstract:
To provide a motor valve capable of reliably detecting a magnetic flux generated by a magnet rotor with a configuration having a relatively small number of components.SOLUTION: A motor valve 1 has: a magnet rotor 41 arranged inside a can 30, a stator 60 arranged outside the can 30, and magnetic sensors 35a, 35b radially facing the magnet rotor 41 via the can 30. The stator 60 has an upper stator 61 and a lower stator. The number of pole teeth of the upper stator 61 and the number of pole teeth of the lower stator are the same. The magnetic sensor 35a and the magnetic sensor 35b are arranged with an interval θ [degrees] shown in the following formula (1): θ=(90/n)+(360×m)/n ... (1), where n is half the number of pole teeth of the upper stator 61, m is an arbitrary integer, and θ<360 degrees.SELECTED DRAWING: Figure 3
