Problems solved by technology

[0004] However, the sealing of the coil winding in the above-mentioned patent document is performed by so-called insert molding in which the coil winding, the terminal pins, and the stator are all integrated with a resin in a state where the coil winding, terminal pins, and stator are supported. Injection molding machine, so there is a problem that requires a huge investment in equipment

Embodiment Construction

[0035] Next, the stator structure of the motor of the present invention will be described with reference to the drawings.

[0036] figure 1 (A), figure 1 (B) and figure 1 (C) are respectively a plan view, a right side view, and an I-I' sectional view after filling the sealing resin of the stator of the motor to which the present invention is applied. figure 2 Yes figure 1 An exploded perspective view of the stator shown. image 3 Yes figure 1 The shown J-J' cross-sectional view of the stator before resin sealing in the cover with the bobbin removed.

[0037] exist figure 1 Among them, the stator of this embodiment is a stator 1 for a stepping motor in which a hole for disposing a rotor (not shown) through a case (not shown) is formed in the center, and the stator 1 has a resin-made body as a cover. The cover 3 includes a bobbin arranging part as a bobbin accommodating part in which a pair of synthetic resin bobbins 21 and 22 are arranged up and down in a form surroundi...

Abstract

The invention provides a stator structure of motor which avoids interference of element contained in the side of stator core and resin filled into the cover. The end faces of walls (411, 421) are opposite, and has gap (D) between top and bottom, so that presses from outside stator core (42) and cover (3) to connect flange parts (214, 211) of bobbin (21) with plans state, opposite plane (412) of outside stator core (41), and opposite plane (816) of inside stator core (81). Similarly, flange parts (224, 221) of bobbin (22) with plans state, opposite plane (422) of outside stator core (42), and opposite plane (826) of inside stator core (82) connects to each other. The opposite planes (817, 827) of the stator cores (81, 82) are also plane state, and connect in whole circle.

Description

technical field [0001] The invention relates to a stator structure of an electric motor. Background technique [0002] In an outdoor unit of an air conditioner, such as a stepping motor that drives a refrigerant flow control valve, a female connection member is connected to the front end of a terminal pin on which a coil winding end is wound, thereby supplying power to the coil winding. Since such a stepping motor is required to have water resistance, a structure is adopted in which the portion of the terminal leg around which the coil winding is wound is sealed with a sealing resin (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-224798 [0004] However, the sealing of the coil winding in the above-mentioned patent document is performed by so-called insert molding in which the coil winding, the terminal pins, and the stator are all integrated with a resin in a state where the coil winding, the terminal pins, and the ...
