Problems solved by technology

[0006] However, in the above-mentioned Patent Document 1, since there is no part for fixing the connection structure and the insulator, it is possible to produce a problem in the circumferential direction when the connection structure is installed. Positional deviation, which hinders the wiring work of winding

Abstract

The invention provides a motor of wiring operation capable of winding more easily and reliably, and a motor-integrated pump equipped with the motor. At least two pins (6) are arranged for binding two end parts (45a,45b) of a winding (45) and clamping a front end part (6a) into a hole (46a) formed on a control substrate (46); a mounting part (61) is laterally protruded toward the control substrate (46) on an insulator (44), and respectively fixes the pin (6) under the condition of laterally protruding toward the control substrate (46); a strengthening wall (63) is laterally protruded toward the control substrate (46) on an insulator (44) and mutually connects between the mounting parts (61,61); further, a strengthening rib (62), which is abutted against the peripheral of a stator core (41, is arranged on the mounting part (61).

Description

technical field [0001] The present invention relates to a motor and a motor-integrated pump including the motor. Background technique [0002] As a conventional motor, there is known a motor that includes a stator core (stator core) formed by laminating a plurality of stator iron plates, and a plurality of teeth portions are provided at equal intervals in the circumferential direction on the inner periphery of the stator core. structure (for example, refer to Patent Document 1). [0003] In Patent Document 1, insulators are respectively provided on both ends in the axial direction of the central axis of the stator core, and a plurality of covering portions covering the outer sides of each tooth portion are provided on each insulator at equal intervals in the circumferential direction. (comb engaging part). And, a winding wire is wound around the tooth portion covered by the covering portion. That is, while ensuring insulation between the teeth (stator core) and the windin...
