Background technology
Now, series excited machine is because having good startup and speed adjusting performance, and structure is simple, starting torque is large, power is large and be widely used in industrial production.The operation principle of series excited machine is that after electric energy inputs motor from electrical network, change mechanical energy into by the electromagnetic action of motor internal, driving mechanical load rotates acting.The torque acted in rotating shaft and load is produced by magnetic field interaction in the electric current in rotor coil and air gap, and magnetic field is produced by stator module.Stator module is made up of stator core and the winding be enclosed within pole shoe, and its effect produces magnetic flux and magnetic conduction; Rotor assembly is made up of rotor core, rotating shaft, armature winding and commutator, and its effect ensures and produces continuous print electromagnetic torque, by rotating shaft band dynamic load acting, is mechanical energy by electric energy conversion.
Stators and rotators is all formed by stacking by some lamelliform motor stampings as motor important component part.The external diameter of stator punching and shape for materials and the economy of cutting out most important, the profile of existing stator punching mostly is the structure that two ends, left and right are circular arc, upper and lower two end-grain cutting Heisei straight flanges, and endoporus is then primarily of the concentric polar arc composition that upper and lower two ends are arranged.Stator punching comprises stator pole body, stator pole shoes and stator slot; Rotor punching comprises equally distributed gear piece, forms rotor between every two gear pieces.The stator that the series excited machine used at present can adopt external diameter to be 95mm and 103mm and supporting rotor, but adopt external diameter to be the stator of 95mm and supporting external diameter to be the power of motor of the rotor of 53.5mm smaller, overload capacity is poor, improving power if want can only adopt external diameter to be the stator of 103mm and supporting rotor, but the increase of external diameter brings thereupon, and weight is bigger than normal, consumptive material is many, high in cost of production shortcoming.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lamination core of series excited machine, and this motor stamping consumptive material is few and cost of manufacture is low, and the power of motor manufactured with it is large, can improve the commutation function of motor, reduces magnetic potential loss.

The present invention improves further and is: described rotor punching is uniform 16 gear pieces circumferentially, and the groove depth of described rotor is 11.5mm.
Owing to adopting technique scheme, the beneficial effect that the present invention produces is:
Adopting the blanking needed for motor stamping of the present invention than making common stator outer diameter is that the blanking volume of the punching of 95mm is less, material-saving 11.4%, and the common external diameter of motor rotor punching sheet external diameter ratio cooperation of the present invention is the large 3.5mm of rotor punching external diameter of the stator of 95mm, rotor diameter is larger, rotor torque is larger, power of motor is larger, so the power making motor can reach larger while on the basis of reducing consumptive material and cost of manufacture.
Stator punching endoporus is the circular arc composition of decentraction, formed stators and rotators is coordinated and forms non-uniform gap, be conducive to improving motor commutation, reduce spark, reduce magnetic potential loss, increase electrical machinery life.
The increasing of rotor groove depth can make rotor area increase, and coiling is increased, and rotor yoke size can be caused little simultaneously, be unfavorable for that the smooth and easy of magnetic flux passes through, preferred rotor punching groove depth of the present invention is 11.5mm, takes into account rotor area and rotor yoke size, makes effect reach best.
Pole shoe arc length is preferably between 61 ~ 64, and the increase of arc length makes magnetic pole area increase thus produce more magnetic fluxs to produce larger torque to drive more heavy load to make rotor, avoids the deterioration of the excessive caused leakage flux increase of arc length and motor commutation simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details:
As shown in Figure 1, lamination core of series excited machine, comprises stator punching 1 and rotor punching 2, and described stator punching 1 comprises stator pole body 1-1, stator pole shoes 1-2 and stator slot 1-3, described rotor punching 2 comprises and is uniformly distributed 16 gear piece 2-2, forms rotor 2-3 between every two gear piece 2-2.
As shown in Figure 2, stator punching 1 exterior contour, for cutting flat structure in four sides, on the basis of rounded outer profile, namely cut out four straight flanges at the four sides of circle, and corner is still for leaving the fillet of circular arc, the stator outer diameter of fillet is 98.5mm, and four sides is cut flat length and width and is of a size of 91mm × 74mm; As shown in Figure 4, punching blanking length and width of the present invention are of a size of 91mm × 74mm, and area is 6734 square millimeters.As shown in Figure 5, making stator outer diameter is that the punching blanking length and width of 95mm are of a size of 95mm × 80mm, and area is 7600 square millimeters; Rotor punching 2 external diameter matched with motor stator punching of the present invention is 57mm, common external diameter is the rotor punching external diameter that 95mm stator matches is 53.5mm, rotor punching external diameter of the present invention goes out 3.5mm greatly, rotor diameter is larger, rotor torque is larger, power of motor is larger, also improves the power of motor by calculating motor stamping of the present invention while material-saving 11.4%.
Stator punching 1 endoporus is made up of upper and lower polar arc 1-4, the center of circle of polar arc 1-4 above below the polar arc 1-4 center of circle below thus formed eccentric, eccentric amount e is 1 ~ 1.5mm, and two polar arc vertex distances are 58.2mm.Form non-uniform gap between the stators and rotators that the design of eccentric arc makes punching be formed, be conducive to improving commutation, reduce spark, reduce magnetic potential loss, increase electrical machinery life.
The pole shoe arc length b of stator pole body 1-1 part is very important, if pole shoe arc length b increases, magnetic pole area is just large, just more magnetic flux can be produced, rotor is made to produce larger torque, thus larger load can be driven, but pole shoe arc length b can bring two shortcomings below after increasing: one is that pole shoe arc length b increases, the pole tip distance of two adjacent poles just shortens, the magnetic resistance of pole tip leakage flux just diminishes, and pole tip leakage flux just increases, therefore, from the angle reducing leakage flux, we do not wish that pole shoe arc length b is too large; Two is that pole shoe arc length b is too large, and commutation also can be made to worsen, and spark increases, and reason is the increase of armature reaction electromotive force.External diameter is slightly larger than common external diameter 95mm stator punching of the pole shoe arc length b of 98.5mm stator punching 1, preferably between 61 ~ 64mm.
The magnet pole widths bp of stator pole body 1-1 part of the present invention is preferably 40 ~ 45mm.Stator yoke height hc is the distance at the bottom of stator slot and between stator outline, and the stator yoke height hc of stator punching 1 of the present invention is 8 ~ 9mm.
As shown in Figure 3, rotor punching 2 is provided with 16 gear piece 2-2, rotor 2-3 is gone between every two gear piece 2-2, groove depth h can strengthen rotor 2-3 area, and coiling is increased, but rotor yoke 2-1 size can be caused little, be unfavorable for that the smooth and easy of magnetic flux passes through, the groove depth h of rotor punching 2 is set to 11.5mm by the present invention, takes into account the area of rotor 2-3 and the size of rotor yoke 2-1, makes effect reach best.
