Abstract

The utility model discloses a stator of a brushless direct current motor with a wiring terminal. The tail leads of the three-phase of the stator are respectively connected with the triad wiring terminal at an insulation shell of the stator of the brushless direct current motor; the head leads of the three-phase of the stator are respectively connected with three independent wiring terminals at the insulation shell of the stator of the brushless direct current motor. The stator adopts the wiring terminal to connect with the three-phase tail leads and the three-phase head leads with the convenience, which facilitates the electric connection between the inside of the motor and the outside and increases the work efficiency.

Description

The stator that has the dc brushless motor of binding post

Technical field

The utility model relates to a kind of dc brushless motor, specifically is a kind of stator that has the dc brushless motor of binding post.

Background technology

Welding is all adopted in being connected between the stator of existing dc brushless motor, connection between common inner winding and winding magnetic wire and lead-out wire, will remove the insulating varnish on the electromagnetic wire during welding, welds again, takes material in actual production, when taking a lot of work.

The utility model content

The purpose of this utility model provides a kind of stator that has the dc brushless motor of binding post, and its neutral point wiring and three-phase output lead all adopt binding post, has simplified himself inner reaching and outside being electrically connected greatly, has improved work efficiency.

The technical solution of the utility model is as follows:

The stator that has the dc brushless motor of binding post, it is characterized in that: the afterbody of its three-phase lead-in wire inserts the three-in-one binding post on the insulation shell of stator of dc brushless motor respectively, and the head lead-in wire of its three-phase inserts three independent binding posts on the insulation shell of stator of dc brushless motor respectively.

Three-in-one binding post is inserted in the tank on the stator insulation housing, and there is the draw-in groove of three band edges of a knife its lower end, and the afterbody down-lead card of described three-phase is in described draw-in groove.

Described independent binding post is to patch reed, is to patch reed, is inserted in the tank on the insulation shell, and patching the reed lower end has band edge of a knife draw-in groove, and described three-phase head lead-in wire is stuck in the described band edge of a knife draw-in groove.

The utility model adopts binding post, can omit the welding sequence that electromagnetic wire is scraped welding between lacquer, the electromagnetic wire and electromagnetic wire and head lead-in wire, has made things convenient for himself inner reaching and being electrically connected of outside, and has improved work efficiency.

Embodiment

The stator that has the dc brushless motor of binding post, the afterbody of its U, V, W phase lead-in

wire

2,4,5 inserts respectively in the draw-in groove of three band edges of a knife 12 of three-in-one binding post 1 lower end on the insulation shell 3 of stator of dc brushless motor, the head of its U, V, W phase lead-in

wire

6,7,8 inserts respectively in the draw-in groove of the band edge of a knife 13 of three independent binding post 9,10,11 lower ends on the insulation shell 14 of stator of dc brushless motor, three independent binding posts the 9,10, the 11st patch reed, and the external circuit lead-in wire can directly be inserted in can realize in the reed that circuit connects.Three-in-one binding post 1, three independent binding posts 9,10,11 are inserted in respectively in the different tank on the stator insulation housing.Because have the edge of a knife in the draw-in groove, draw-in groove rides over when depressing on the lead-in wire, the outer insulation paint film of enamelled wire is wiped off, promptly with the draw-in groove conducting.
