Abstract
The utility model relates to a single phase motor stator lamination structure. The outer profile of the single phase motor stator lamination structure is formed by the connection of transition concentric arc line segments among four straight line segments and the adjacent straight line segments. Each two straight line segments in the four straight line segments are parallel, and the four straight line segments are divided into two groups which are mutually vertical; one group of the parallel straight line segments are longer, and the other group of the parallel straight line segments are shorter; the center circular hole of the stator lamination is distributed with a main winding and an excitation winding or the groove occupied by a secondary winding along the circumference; the excitation winding or the groove occupied by the secondary winding is arranged at the position along the circumference of the center circular hole opposite to the longer straight line segments of the stator lamination, and are symmetrically distributed at the two ends of the arc line segment of the circumference part, taking the center line of the longer straight line segments as the boundary, and the middle reserved arc line segment is not arranged grooves; the empty grooves of the original stator lamination are canceled. The motor stator lamination structure can decrease the consumption of raw materials, reduce the volume, alleviate the weight, and simultaneously can improve the output power of the motor.
Description
Technical field
The utility model belongs to motor technology, is specifically related to be applicable to the motor stator punching of single-phase alternator, motor.
Background technology
In order to improve the utilance of silicon steel sheet, the profile of the stator punching of mass-produced in the market single-phase AC motor, generator is not complete circle, but is designed to the shape of Fig. 1.Figure 1 shows that the stator punching of a single phase synchronous generator, the main electric property parameter of this generator is: power 2KW, voltage 220V, rotating speed 3000r/min, frequency 50Hz.The outline of stator punching is that the isocentric circular arc line segment by transition between four straightways and adjacent straight line segment is connected to form, article four, straightway is parallel in twos is divided into two groups, two groups vertical mutually again, one group of Line Segment is longer among the figure, two 1 groups of Line Segment are longer, thereby make one group of length a between the Line Segment greater than the length b between another group Line Segment, Φ A and Φ B are concentric circless.The center hole of stator punching circumferentially has groove, and symbol x is motor excitation winding or the shared groove of auxiliary winding among the figure, and symbol y is a dead slot, and all the other are the shared groove of main winding, and the shape of all each grooves is all identical with size.There is irrationality in this design of stator punching, mainly show: the outline of (1) stator punching is that the width K1 of yoke portion of straightway part is the width K2 of yoke portion of circular arc line part much smaller than outline, thereby cause the former yoke portion magnetic close much larger than the latter, this will cause raw materials consumption increase or power output to descend.(2) because the shape of each groove and big or small identical, and in fact the needed groove area of excitation winding is less relatively, so the copper factor of the groove that occupies of excitation winding is too low, makes the utilance of effective material low.(3) because dead slot is not fully used, also cause waste of raw materials.
Summary of the invention
The purpose of this utility model is to provide a kind of monophase machine stator laminating structure that improves structure at the stator punching above shortcomings of existing single-phase AC motor, generator, with the reduction raw materials consumption, or the power output of raising motor.
The technical solution of the utility model is as follows:
This monophase machine stator punching, be under the situation of the outline structure that keeps existing motor stator punching, excitation winding or groove that auxiliary winding occupied designed respectively be positioned at the center hole relative along circumferential position with the longer straightway of stator punching, and be the two ends that bound pair claims to be distributed in this part arc of circumference with the center line of this longer straightway, one section arc that the centre is reserved is not established groove, such design, increase the yoke portion width of longer straightway counterpart, make the yoke portion close trend of magnetic of stator punching even.
Further, excitation winding wherein or groove that auxiliary winding occupied are designed to sulculus, its area design is the area less than the vat that main winding occupied, and has dwindled the area of the groove that excitation winding occupies, and also helps to make the yoke portion close trend of magnetic of stator punching even.Further again, except that above-mentioned excitation winding or groove that auxiliary winding occupied, circumferential all the other grooves of the center hole of this motor stator punching are the groove that main winding occupies, so just cancelled the dead slot of motor stator punching, a value among Fig. 1 is descended, reduce material consumption, improve the stock utilization of stator punching.
Adopt above-mentioned two kinds of monophase machine stator punchings that improve structure, compare with the stator punching of existing single-phase AC motor, generator, have following advantage: when the main electric property parameter of single-phase AC motor, generator remained unchanged, the former raw materials consumption and volume and weight were all less than the latter; When raw materials consumption and volume and weight remained unchanged, the former power output was greater than the latter.
Therefore, the motor stator punching that improves structure can reduce raw materials consumption, reduces volume, weight reduction, and the while can be improved the power output of motor again.
Description of drawings
Fig. 1 is a kind of stator laminating structure figure of existing single phase synchronous generator;
Fig. 2 is by a kind of structure chart of the stator punching of the single phase synchronous generator after the utility model architecture advances.
Embodiment
Referring to Fig. 2, this motor stator punching is the improvement of carrying out on the basis of Fig. 1, the outline of motor stator punching 1 is that the isocentric circular arc line segment by transition between four straightways and adjacent straight line segment is connected to form, 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, and another group Line Segment is shorter relatively, and the length a among the figure between the parallel one group of straightway in the left and right sides is greater than the length b between one group of parallel up and down straightway.The center hole of stator punching circumferentially has groove, is respectively the groove 3 that the groove 2 that occupies of main winding and excitation winding are occupied.Wherein the groove 3 that excitation winding is occupied is arranged on the center hole relative with the longer straightway 4 of stator punching along circumferential position, and be the two ends that bound pair claims to be distributed in this part arc 5 of described circumference with the center line of this longer straightway 4, the arc 5 that the centre is reserved is not established groove.The shape of the groove 3 that excitation winding is occupied and area size design according to suitable copper factor, are less than groove 2 areas that main winding occupied, as shown in Figure 2 with its area design preferably.
After adopting said structure, the silicon steel sheet consumption of generator has descended 9.4%, and volume and weight also descends thereupon, and power output has but risen 10%, and all the other electric property parameters remain unchanged.
Structure shown in Figure 2 also is applicable to single-phase synchronous motor and monopole asynchronous motor.
