Abstract

The utility model discloses a dipole single-phase generator and motor stator plate. Two excitation winding inserted line slots and two main winding inserted line slots are distributed around the central circular hole of the inner contour of the utility model, while the outer contour is formed by connecting four line segments and their neighboring transitional arc segment of the center circular hole, wherein the four line segments are divided into two units, each of which are two parallel line segments and the two units are mutual perpendicular, wherein one unit is longer than the other one. The excitation winding inserted line slots face the longer line segments, wherein a part or the whole groove bottom of the excitation winding inserted line slots is on the same linear which is mutually parallel to the longer line segments and the area of the excitation winding inserted line slots is smaller than that of the main winding inserted line slots. The utility model not only saves raw materials, but also makes the magnetic yoke of the excitation winding inserted line slots to be in basic conformity with that of the main winding inserted line slots. With the simple structure and easy implementation, the utility model has advantages of saving the materials and the production cost.

Bi-pole single-phase generator, motor stator punching

Technical field

The utility model belongs to technical field of motors, specifically, relates to a kind of bi-pole single-phase generator, motor stator punching.

Background technology

Existing mini-type bi-pole single-phase generator, motor stator punching, the center hole of the interior profile of punching body circumferentially has two groups of excitation winding line embedding grooves and two groups of main winding line embedding grooves, excitation winding line embedding groove group and main winding line embedding groove group are provided with at interval, and the shape of excitation winding line embedding groove and main winding line embedding groove and area equate; The outline of punching body is connected to form by the concentric circles segmental arc of four straightways and adjacent transition, and four straightways are parallel in twos to be divided into two groups, and two groups vertical mutually again, and wherein one group of Line Segment is longer, and length of another group Line Segment is shorter relatively.Because the line embedding groove of four straightway correspondences, particularly the yoke portion of excitation winding line embedding groove and tooth portion magnetic flux density are very high, iron loss and eddy current loss increase, and the whole temperature rise of motor is increased, and efficient reduces, and the required number of turn of stator excitation winding is less, groove area is too big, and copper factor is too low, causes excitation winding loosening in groove, when work, easily cause under the electromagnetic force effect and hinder line, excitation winding is damaged.

The utility model content

For solving above technical problem, the purpose of this utility model is to provide a kind of bi-pole single-phase generator, motor stator punching that can guarantee that yoke portion and tooth portion magnetic flux density are consistent substantially between excitation winding wire casing and the main winding wire casing.

The technical solution of the utility model is as follows: a kind of bi-pole single-phase generator, motor stator punching, the center hole of the interior profile of punching body circumferentially has two groups of excitation winding line embedding grooves and two groups of main winding line embedding grooves, and excitation winding line embedding groove group and main winding line embedding groove group are provided with at interval; The outline of punching body is connected to form by the concentric circles segmental arc of four straightways and adjacent transition, article four, straightway is parallel in twos is divided into two groups, two groups vertical mutually again, wherein one group of Line Segment is longer, the length of another group Line Segment is shorter relatively, its key is: described excitation winding line embedding groove group is over against longer straightway, the part or all of bottom land of middle on the same group excitation winding line embedding groove is located along the same line, this straight line is parallel to each other with corresponding longer straightway, and the area of excitation winding line embedding groove is less than the area of main winding line embedding groove.

The utility model is on the basis of original structure, the geomery of main winding line embedding groove is constant, the excitation winding line embedding groove is dwindled, make the area of the area of excitation winding line embedding groove less than the main winding line embedding groove, can guarantee that the yoke of excitation winding line embedding groove part and the yoke of main winding line embedding groove part are consistent substantially, guarantee excitation winding line embedding groove part yoke and tooth portion magnetic flux density and main winding line embedding groove part yoke and tooth portion magnetic flux density basically identical, make leakage field reduce, thereby guarantee that whole electric efficiency is constant, iron loss and eddy current loss reduce, and the temperature rise of motor reduces.

In the above-mentioned main winding line embedding groove group over against being special-shaped main winding line embedding groove group than the short lines section, the part or all of bottom land of special-shaped main winding line embedding groove is located along the same line on the same group, this straight line parallel in correspondence than the short lines section, and the area of special-shaped main winding line embedding groove is less than the area of main winding line embedding groove.

By part main winding line embedding groove is dwindled, can correspondingly reduce the outer profile size of stator punching, saved raw material greatly.

Outline at above-mentioned punching body is circumferentially jagged, and the bottom of this breach is provided with semicircle bonding pad.Can be by bonding pad so that iron core is formed in a plurality of stator punching stack welding.

Beneficial effect: the utility model is compared with existing structure, when guaranteeing that yoke portion and tooth portion magnetic flux density are consistent substantially between excitation winding line embedding groove and the main winding line embedding groove, have simple in structure, implement advantages such as easy, economical with materials and cost.
