Abstract
The invention designs an energy-saving motor stator. The energy-saving motor stator comprises a stator body and is characterized in that the stator body is composed of an inner iron core and an outer iron core which are fixed by virtue of interference fit of the outer periphery of the inner iron core and the inner periphery of the outer iron core, wherein the outer iron core is a circular ring structure; the inner periphery of the inner iron core is enclosed; the outer periphery of the inner iron core is grooved to form a radial structure from inside to outside; the grooves are wire winding grooves; and each of groove openings is provided with steps for blocking wires. According to the energy-saving motor stator designed by the invention, by virtue of the groove opening design of the inner iron core of the stator body, automatic wire winding can be conducted directly by a wire winding machine outside the stator, thereby enabling winding coils in the end part to be short, reducing the usage amount of enameled wires, reducing the winding resistance, and thus improving the motor working efficiency. At the same time, the inner periphery of the inner iron core of the stator body is an enclosed structure with a thickness of 0.2-0.6 millimeters so that the magnetic leakage between teeth of the stator can be reduced effectively and the motor efficiency can be further improved.
Description
Technical field
The present invention relates to field of motor manufacturing, particularly a kind of energy-saving electric machine stator.
Background technology
In prior art, the structure of motor stator is all structure as a whole, and in internal diameter, slots, and fluting is for convenience of coil winding machine coiling.Although this mode and comparatively ripe, the enamelled wire quantity of using is larger, and the resistance of motor is increased, and caloric value and energy loss are more.Due to inside fluting, coil produces leakage field, has also caused energy loss on the other hand.
Summary of the invention
The object of the invention is to provide in order to solve the deficiency of above-mentioned technology a kind of can use enamelled wire quantity few under same volume, makes the energy-saving electric machine stator that final motor power utilance is high.
In order to achieve the above object, the energy-saving electric machine stator that the present invention is designed, comprises stator, it is characterized in that stator is comprised of interior iron core and outer iron core, and fixes by the external diameter of interior iron core and the internal diameter interference fit of outer iron core; Described outer iron core is circular ring structure; Radial structure is from inside to outside slotted in the internal diameter sealing of described interior iron core on external diameter, and described fluting is winding slot, is provided with the step of gear line on each notch.
Further scheme is, described winding slot is straight-tooth groove or bending teeth groove, and described groove inwall is to the thickness that has 0.2-0.6 millimeter between the internal diameter of interior iron core.
The energy-saving electric machine stator that the present invention is designed, by iron core slot opening in stator, design, can directly there is the outer coil winding machine automatic winding of stator, make end winding wire bag short, reduce enamelled wire use amount, reduced winding resistance, thereby promoted motor working efficiency, in stator, iron core internal diameter is enclosed construction simultaneously, and thickness is 0.2-0.6 millimeter, can effectively reduce the leakage field between stator tooth and tooth, further improve electric efficiency.This motor stator, when producing, first obtains interior iron core, after interior iron core winding completes, coordinates with outer iron core again, whole by press crimping moulding stator.Meanwhile, this energy-saving electric machine stator can be widely used in alternating current machine, especially air conditioner fan motor, motor for washer, lampblack absorber fan motor and three-phase industrial motor.
