Embodiment Construction

[0019] Below, while referring to the attached Figure 1 Exemplary embodiments of the present invention will be described. In addition, in this application, the direction parallel to the central axis of the motor is referred to as "axial direction", the direction perpendicular to the central axis of the motor is referred to as "radial direction", and the direction along the central axis of the motor is referred to as "radial". The direction of the arc is referred to as "circumferential". In addition, in this application, the shape and positional relationship of each part are demonstrated using the axial direction as an up-down direction, and the terminal pin side as an upward direction with respect to a stator core. However, the definition of the up-down direction is not intended to limit the orientation when manufacturing and using the motor of the present invention.

Abstract

A stationary part, a motor, and a method of manufacturing the motor are provided. The stationary part of the motor has a terminal pin that electrically connects the conduction member and the coil. A portion of the terminal pin is exposed from the housing. A conductor is led out from the coil along the surface of the insulator. Moreover, the front end of the conductor is connected to the terminal pin. Further, the insulator has a sealing portion on the surface of the insulator that at least partially blocks the space around the conductor. Therefore, the resin can be prevented from passing through the space around the conductor and entering the vicinity of the terminal pin when molding the outer casing.

Description

technical field [0001] The present invention relates to a stationary portion of a motor, a motor having the stationary portion, and a method of manufacturing the motor. Background technique [0002] Conventionally, a so-called molded motor in which a stator is covered with resin is known. For example, a conventional molded motor is described in Japanese Laid-Open Publication No. H10-174338. In the structure of this publication, the winding end is connected to the terminal block via the terminal metal fitting. Also, the stator and the terminal block are covered with molded resin. [0003] However, there are cases where a terminal block or a circuit board connected to the terminals is mounted after molding. In this case, it is necessary to expose a part of the terminal from the molding resin. Therefore, for example, it is conceivable to use a mold to cover the periphery of the terminal pins during molding so that resin does not flow into the terminal pins. However, a slig...
