Abstract
The utility model belongs to the technical field of motor equipment and relates to a rotor punching sheet groove shaped structure on a large and medium-size wire wound type asynchronous motor; the rotor punching sheet groove shaped structure is characterized in that: the rotor punching sheet groove shape adopts a closed parallel type groove shaped structure, and the width of the groove opening is 0-3mm, therefore, by adopting the structure, the manufacturing process of a coil is simplified, the efficiency and quality of the embedded coil are improved, the bending arc guide function of the end part of the coil can be realized by a simple mold, the cost of the mold can be greatly saved, the effect of harmonic waves on the motor is reduced and the efficiency of the motor is improved.
Description
Technical field
The utility model belongs to the motor device technical field, particularly relates to a kind of big-and-middle-sized wire wound asynchronous motor upper rotor part punching bathtub construction that is applicable to.
Background technology
Because the rotor coil conducting wire sectional area is bigger, and the cross section length-width-ratio is bigger, therefore for the ease of the end winding bending, above-mentioned motor must adopt open slot to present big-and-middle-sized wire-wound asynchronous motor, sees also Fig. 1 mostly.But the end winding bending must be finished before rule in this case, must increase the complicated Bending Mould of a cover in manufacture process, and the size after the bending can't guarantee unifiedly, therefore still needs to adjust inefficiency behind rule; Owing to the influence of slot ripples, electric efficiency can reduce in addition, and this is for generator, and defective will be more obvious.Also there is motor to adopt semi-open slot, see also Fig. 2, though reducing harmonic wave influences motor, but when the setting-in coil the difficulty, greatly reduce efficiency, and in the rule process coil easy damaged, have a strong impact on motor quality, when adopting the semi-open slot structure, coil is made and is still needed complicated die, has increased the motor manufacturing cost.
Summary of the invention
The utility model provides a kind of large wound formula that is applicable to asynchronous motor upper rotor part punching bathtub construction of being convenient to make coil, raising coil setting-in efficient, saving coil manufacturing cost and improving motor performance for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind ofly be applicable to big-and-middle-sized wire wound asynchronous motor upper rotor part punching bathtub construction, it is characterized in that: described rotor punching flute profile adopts the run-in index bathtub construction of remaining silent.
The utility model can also adopt following technical measures:
The width of described flute profile notch is 0～3mm.
Advantage and the good effect that the utlity model has are: because the utility model rotor punching flute profile adopts the run-in index bathtub construction of remaining silent, thereby simplified the manufacturing process of coil, the efficient and the quality of setting-in coil have been improved, only need very simple mould just can realize that the bending of end winding leads the arc function, having saved the cost of mould greatly and having reduced harmonic wave influences motor, has improved efficiency of motor.
Description of drawings
Fig. 1 is known opening slot type rotor punching structural representation;
Fig. 2 is known half opening slot type rotor punching structural representation;
Fig. 3 is the utility model structural representation;
Fig. 4 is an I portion enlarged drawing among Fig. 3.
Among the figure: 1, rotor punching; 2, flute profile notch.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 3 and Fig. 4,
A kind ofly be applicable to big-and-middle-sized wire wound asynchronous motor upper rotor part punching bathtub construction, it is characterized in that: described rotor punching 1 flute profile adopts the run-in index bathtub construction of remaining silent, and the width of flute profile notch 2 is 0～3mm, and the width of present embodiment flute profile notch is 2mm.Adopt said structure to simplify the manufacturing process of coil, the efficient and the quality of setting-in coil have been improved, only need very simple mould just can realize that the bending of end winding leads the arc function, cost and the reduction harmonic wave of having saved mould greatly influence motor, have improved efficiency of motor.
The above only is to preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification all belong in the scope of technical solutions of the utility model.
