Abstract: The invention intends to improve a stator which is detachably installed to an outer peripheral portion of a can accommodating a rotor. The stator is integrally formed with a resin mold by arranging a stator assembly (110) within metal molds (300, 310) and injecting a molten resin (P1) from a gate (G1) at one position. An annular plate (160) is mounted to an upper portion of the stator assembly (110) so as to prevent the molten resin from intruding into magnetic pole teeth (120a, 122a), and prevent a weld line from being generated in an outer peripheral surface of the resin mold.

Abstract: An object of the present invention is to provide an electrically operated valve capable of more accurately detecting the position of a valve body. In order to achieve the above object, the electrically operated valve of the present invention comprises a valve body, a driver configured to move the valve body along a first axis, a rotation shaft configured to rotate the driver around the first axis, a permanent magnet member, and an angle sensor. The permanent magnet member is disposed on the rotation shaft and configured to rotate with the rotation shaft. The angle sensor is configured to detect a rotation angle of a permanent magnet included in the permanent magnet member. The angle sensor is disposed above the permanent magnet.

Abstract: An electric valve can be further miniaturized while reducing the number of manufacturing man-hours. The electric valve contains: a motor including a stator member and a rotor member that displace a valve body, and a housing for accommodating the motor. The housing is formed by joining a heat generation portion formed of a first material to a heat receiving portion formed of a second material. The light transmittance in the first material is lower than the light transmittance in the second material.

In order to achieve the above object, the electrically operated valve of the present invention comprises a valve body, a driver configured to move the valve body along a first axis, a rotation shaft configured to rotate the driver around the first axis, a permanent magnet member, an angle sensor, and a yoke configured to cover a portion of the permanent magnet or a portion of the angle sensor. The permanent magnet member is disposed on the rotation shaft and configured to rotate with the rotation shaft. The angle sensor is configured to detect a rotation angle of a permanent magnet included in the permanent magnet member. The angle sensor is disposed above the permanent magnet.

Abstract: The invention provides an electrically operated valve which can more accurately detect a position of a valve body. An electrically operated valve is provided with a valve shaft, a valve body, a rotor member which is movable together with the valve shaft in a parallel direction to a first direction, a stator member which applies a turning force to the rotor member, a permanent magnet member which turns together with the rotor member, an angle sensor which detects an angle of rotation of the permanent magnet, and a guide member which guides a relative movement of the rotor member or the valve shaft in relation to the permanent magnet member. A distance between the permanent magnet and the angle sensor is fixed when the permanent magnet member turns.
