Description
Technical field
The utility model relates to a kind of motor, particularly a kind of monopole asynchronous motor.
Background technology
Monopole asynchronous motor is widely used in various small-sized machines and the household electrical appliance.On its stator core, except that main winding, must lay auxiliary winding and could produce detent torque.Because the needs of performance and cost, most of monopole asynchronous motor major-minor winding is also inequality, and each coil turn of each winding is also inequality, but the flute profile of stator punching, groove area are all identical or only divide two or three kind, cause each groove copper factor inequality, need adjust the restriction that each coil turn satisfies copper factor passively.Such result is that motor efficiency is on the low side and cost is higher.
In the prior art, the special-shaped groove that has is two kinds of flute profiles, and what have is three kinds of flute profiles, can not solve winding distribution needs fully.The change that has tooth boots width, adopt and not wait the tooth boots, the distribution that this has changed air-gap field is unfavorable for the optimization of motor performance.
The utility model content
The purpose of this utility model aims to provide the monopole asynchronous motor that a kind of simple and reasonable, yoke portion magnetic is close evenly, tooth portion magnetic is close evenly, the operation noise is low, vibration is low, applied widely, to overcome weak point of the prior art.
A kind of monopole asynchronous motor by this purpose design, comprise stator core, stator winding and rotor, stator core is formed by the stator punching stack, stator punching is provided with several stator punching yoke portions, stator punching tooth portion, tooth boots and stator punching groove, stator winding comprises main winding and auxiliary winding, it is characterized in that main winding and auxiliary winding space be separated by 90 the degree.
Mutually disjoint in the center line of described stator punching tooth portion and the center of circle of stator punching.
The slanted angle that the center line of described stator punching tooth portion and horizontal line form is different.
Described stator punching is a full circle shape structure, and each stator punching yoke portion equates to the distance of the neighboring of stator punching; Perhaps stator punching is circular side cut structure, and on the concentric circles circumference of different radii, each stator punching yoke portion equates to the distance of the neighboring of stator punching the bottom land of stator punching groove according to the side cut size distribution.
The shape symmetry of the stator punching groove of each of described stator punching under extremely, shape difference, the area difference of half each stator punching groove under extremely.
The notch of described tooth boots and stator punching groove evenly distributes.
When the utility model was two pole motors at monopole asynchronous motor, the shape of the stator punching groove in per half extremely following 90 ° scopes of stator punching was different; When monopole asynchronous motor was four-pole motor, the shape of the stator punching groove in per half extremely following 45 ° scopes of stator punching was different, and and the like.
The utility model distributes according to the stator winding of monopole asynchronous motor optimal design, convert on each stator punching groove, calculate the required groove area of each stator punching groove, according to the concrete shape of each groove area design stator punching groove, make to produce different flute profiles and the groove area that is adapted to winding on the stator punching; Again according to the groove area needs, wait tooth portion width, etc. yoke portion design stator punching to heavens.
The utility model exists each coil turn of stator winding at existing monopole asynchronous motor and does not wait, and the shape of stator punching groove, area equates or has only two or three kind shortcoming, be difficult to satisfy the big winding needs of copper factor difference of each stator punching groove, and adopted the center line of stator punching tooth portion and the center of circle of stator punching to mutually disjoint, each stator punching groove shape difference, the area difference, equally distributed design of the notch of stator punching groove and fabrication scheme, solved the contradiction that optimized winding distributes and the stator punching flute profile distributes, it is by the cooperate optimization of the flute profile of winding and stator punching groove, make Distribution of Magnetic Field more reasonable: yoke portion magnetic is close evenly, tooth portion magnetic is close evenly, guaranteeing on the energy-efficient basis of motor, realized that the motor operation noise is lower, vibrate lowlyer, and also reduced the cost of manufacture of motor simultaneously.
The utility model had both satisfied the number of turn distribution needs of each coil of stator winding, again because the inclined design of stator punching groove: mutually disjoint in the center line of stator punching tooth portion and the center of circle of stator punching, make the tip spacing in the stator punching groove reduce, be that coil spread reduces, reduced the end copper consumption, solved each coil distribution of winding of optimization and the contradiction that the stator punching flute profile distributes, realized that winding optimization is not subjected to the restriction of punching flute profile groove area, more reasonable, the copper factor uniformity of Distribution of Magnetic Field.
The utility model is applicable to the motor of different numbers of poles, and perhaps main winding number, auxiliary winding coil number difference, the different motor of groove number, and the punching altogether variform motor of cutting edge has advantage of wide range of application.
