摘要： [Object] To provide a stator unit capable of inhibiting water from entering an inner space of a yoke and inhibiting a coil wire from breaking, an electric valve, and a method for manufacturing the stator unit.
[Solution] A stator unit 80 includes an A-phase yoke 81A, a B-phase yoke 81B, a first resin portion 85-1, and a second resin portion 85-2. The A-phase yoke 81A and the B-phase yoke 81B include pole teeth. The first resin portion 85-1 includes an A-phase yoke filling part 86A in an inner space of the A-phase yoke 81A and a B-phase yoke filling part 86B in an inner space of the B-phase yoke 81B. The second resin portion 85-2 includes a sealing part 89 between the pole teeth. An A-phase bobbin 82A separates the A-phase yoke filling part 86A from the sealing part 89. A B-phase bobbin 82B separates the B-phase yoke filling part 86B from the sealing part 89.

摘要： The purpose of the invention is to provide a motor in which it is possible to efficiently construct a structure wherein a terminal part of a motor body is covered by a terminal cover. This terminal cover (7) is a resin molded article integrally including a first member (8) fixed to a motor body (40), a second member (9) that covers the first member (8), and a hinge part (70). Thus, the first member (8) and the second member (9) can be engaged with one another by first fixing the first member (8) to the motor body (40), and then rotating the second member (9) at the hinge part (70) and covering the first member (8) with the second member (9). Thus, the number of components can be reduced compared to cases where the first member (8) and the second member (9) are constructed as separate members, and the task of attaching the second member (9) to the first member (8) can be performed efficiently.

摘要： A linear stepper motor includes a stator (5), a rotor (6), a cover (4) and a longitudinally displaceable actuating rod (1). The stator (5) is formed as a fully overmoulded stator assembly (17). The stator assembly (17) includes a stator overmould (12). The rotor (6) is received in the stator and includes a spindle (13). The cover (4) is coupled to the stator assembly (17) on the drive side of the linear stepper motor. The actuating rod (1) is guided by the stator assembly (17). The spindle (13) is only supported by its tips between two bearing balls (9) between a stator recess (14) of the stator overmould (12) and a cover recess (15) in the cover (4). A device and a method for manufacturing the linear stepper motor are also provided. The invention relates to a linear stepper motor as well as a device and method for manufacturing a linear stepper motor.

摘要： A motor device includes a stator core (26), and a positioning structure that positions the stator core (26). The stator core (26) is constituted by multiple core members (30) arranged around a rotor (14) in circumferential directions. The core members (30) each have multiple teeth parts (36) of which the front end surfaces radially face the rotor (14). The positioning structure includes multiple positioner parts (44) that respectively abut against the multiple core members (30) to position the multiple core members (30). The multiple positioner parts (44) include first positioner parts (44-A) that each abut against a front end part of a teeth part (36) of each of core members (30) adjacent to each other in the circumferential directions.

摘要： There is provided an inner-rotor-type motor, which makes it possible to easily and cost-effectively manufacture a cover member without impairing the dust-proofness of the interior of the motor and which enjoys a greatly improved ease of assembly. In the inner-rotor-type motor, four outer surface portions substantially flush with the motor outer surface of the core-back portion are formed in the frame portion of each of the two insulating members of the insulator for securing insulation between the stator core and the coil. The outer surface portions of the frame portion of each of the insulating members are inserted between the leg portions of four corners of each of the cover members attached to the axial opposite sides of the stator core. In this state, the cover members are attached to the stator core.
