Abstract
The utility model relates to a stator pole of DC electric machine. The stator pole (3) is formed by single-chip pole laminations (1) which are superposed and connected by a cylindrical pin (2) in a penetrating way. The edge of the chip pole lamination (1) is symmetrically provided with four perforating pin holes (4). The cylindrical pin (2) with one end upsetting orderly penetrates through the perforating pin holes, and the other end of the cylindrical pin (2) is riveted with the pole lamination (1) shaped in a bowler hat with edges and angles designed to be circular arc transition. After adopting the above technical scheme, the working condition is greatly improved, the insulating property between the pole laminations is increased, the magnetic vortex during the running of the motor is reduced, the performance of the motor is improved and the efficiency is improved.
Description
Technical field
The utility model relates to the direct current machine field, more specifically relates to a kind of DC motor stator magnetic pole.
Background technology
In the low voltage DC motor magnetic pole course of processing, adopt usually and on pole lamination, go out weld seam groove 5, carry out the method manufacturing that argon arc welding connects behind the pole sheet.The pole lamination both sides respectively dash has two grooves as shown in Figure 4, the reason sheet, laminate after, for guaranteeing magnetic pole enough intensity is arranged, need carry out sealing weld at pole lamination to two weld seam grooves 5 of both sides, form two weld seams 6, make it into as a whole, as shown in Figure 3; During welding, the flue gas of generation can cause certain destruction to environment, and the arc light that produces of welding also can produce radiation and damages; Pole lamination forms an integral body after because of melting welding, makes the both sides conducting, has increased the magnetic pole eddy current, thereby has influenced motor performance; Because magnetic pole two ends corner angle rounding, two ends pole lamination are prone to the sheet phenomenon of loosing.
The utility model content
Problem to be solved in the utility model provides a kind of DC motor stator magnetic pole, its objective is the raising work efficiency, promotes motor performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of DC motor stator magnetic pole, to form by pole lamination, and described magnetic pole of the stator is formed by the straight pin cross-under by monolithic pole lamination stack back.
Described monolithic pole lamination edge is provided with four pinned holes symmetrically, and the straight pin of an end jumping-up passes wherein successively, the other end of straight pin and pole lamination riveted joint.
One side of described pole lamination is provided with the mark groove.
Be arranged with pinned hole in a distance, distance pole lamination edge, penetrate the straight pin of an end jumping-up during pole lamination reason sheet, after lamination reaches specific length, compress, the straight pin other end is riveted tightly.
Adopt the riveting technology, improved the insulation property between the pole lamination lamination, the magnetic eddy current when having reduced the motor operation has promoted motor performance, simultaneously, riveting makes the magnetic pole two ends more firm, and the diffusing sheet phenomenon when having stopped magnetic pole two ends rounding has improved reliability.
Described pole lamination is the carnival hat shape, and limit, angle all are set to the circular arc type transition.
A kind of DC motor stator magnetic pole of the utility model adopts technique scheme, and the smog and the arc light radiation that have produced when having stopped welding have improved operational environment greatly; Need not carry out sealing weld, improve work efficiency; Adopt the riveting technology, improved the insulation property between the pole lamination lamination, the magnetic eddy current when having reduced the motor operation has promoted motor performance; Riveting makes the magnetic pole two ends more firm, and the diffusing sheet phenomenon when having stopped magnetic pole two ends rounding has improved reliability.
