Fig. 3 is a rotor punching structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly includes casing 1, stator 2, rotor 3 and rotating shaft 4.Described casing 1 is clamped in the two ends that expose stator 2 by front end housing 11 and rear end cap 12 by fastening bolt 13, and shaft of motor 4 is stretched out from front end housing 11.Front end housing 11 shown in the figure and rear end cap 12 are cup type end cap, are provided with a place on the cylindrical of end cap at least and protrude rectangle lug 14, are drilled with the two fixing screws 15 of using on this lug 14, and it can be used for motor mounting or clamps equipment.Front end housing shown in the figure is provided with boring, and outlet 5 direct borings from this front end housing 11 are drawn, and have omitted terminal box.
Shown in Figure 2, exposed stator 2 described in the utility model is to be overrided to form by many punchings 21, and round wire casing 22 down reaches 24 grooves in every punching, and is flat peariform slot or round bottom peariform slot.The W flute profile 23 that is provided with the welding that is used to laminate stator is everywhere arranged on stator punching 21 cylindricals shown in the figure.Exposed stator described in the utility model is to be formed by stacking by many punchings, its groove shape uniqueness that rolls off the production line, and following wire casing quantity is Duoed one times than the motor of identical size.Therefore, the total amount that rolls off the production line is more relatively, and the synchronous rotating magnetic field energy of stator is bigger.
Shown in Figure 3, rotor 3 described in the utility model is to be overrided to form by many punchings 31, and the cylindrical punching out of punching 31 has a plurality of slotted eyes 32, the middle arc magnet steel groove 33 that is used to install the arc magnet steel that 4 groove symmetries are arranged that dashes.The endoporus of the rotor punching 31 shown in the figure dashes the axis hole 34 that is useful on the tape character groove that rotating shaft is installed.
Therefore the utility model reduces motor noise and mechanical loss greatly owing to be not with fan; And exposed stator can make the temperature of motor dispel the heat rapidly.
