Kind Code:
A1
Abstract:
[Problem] To provide a stator unit and an electric valve by which it is possible to mitigate the entry of moisture into the internal space of a yoke as well as mitigate disconnections in a coil, and to provide a manufacturing method for the stator unit. [Solution] A stator unit 80 has an A-phase yoke 81A, a B-phase yoke 81B, a first resin part 85-1, and a second resin part 85-2. The A-phase yoke 81A and the B-phase yoke 81B have a plurality of pole teeth. The first resin part 85-1 includes an A-phase yoke filing section 86A present in the internal space of the A-phase yoke 81A, and a B-phase yoke filling section 86B present in the internal space of the B-phase yoke 81B. The second resin part 85-2 includes a seal section 89 present in a space between the plurality of pole teeth. An A-phase bobbin 82A partitions the A-phase yoke filling section 86A from the seal section 89, and a B-phase bobbin 82B partitions the B-phase yoke filling section 86B from the seal section 89.
