Abstract

The utility model relates to a permanent magnetic AC generator, which belongs to the technique of generators. The utility model comprises a machine casing, end covers which cover the two ends of the machine casing, stator iron cores arranged on the wall of the inner circle of the machine casing, machine shafts arranged on the end covers, rotors fixed on the machine shafts, and a barostat connected with windings electrically. The size of the utility model is equal to the size of ordinary generators. The output power of the utility model is 1.2 times as the output power of the ordinary generators under a same rotary speed.

Description

Magneto alternator

The utility model belongs to the technical field of generator.

Present tractor with small four wheels and the automobile-used lighting generator of motor tricycles, it all is general common generator, at meeting, turn to and condition of road surface when not good enough, when particularly condition of road surface was not good, the driver needed strong lighting, but because of the speed of a motor vehicle low, engine output is little, thereby the power output of generator is accordingly also little, thereby can not satisfy the requirement of safety traffic, thus unnecessary appearance accident potential.

The purpose of this utility model provides a kind of identical with other generator volume, the twice generator of power output.

This magneto alternator comprises casing, the support that is connected with casing, cover end cap at the casing two ends, the arbor of end cap is stretched out at two ends in casing, at the stator core of casing internal fixation on the casing internal perisporium, be pressed in the coil in the stator core groove, be fixed on the planchet iron on the casing inner segment arbor, be fixed on the multitudinous machine formula rotor on the planchet iron, be contained in the barostat that is electrically connected with coil on the casing periphery wall.

Because the line of coil directly changes and the minimizing of the number of turn of coiling, reduced the copper loss rotor and changed multitudinous machine formula into by pawl machine formula, thereby increased power output, make that installing to the power that the generator on the small tractor exports when low-speed running can make the brightness of the illuminating lamp of vehicle reach the brightness that reaches when the common vehicle generator runs well, thereby can drive safely, eliminate accident potential.

Accompanying drawing shows embodiment of the present utility model, wherein;

Figure 1 shows that the cutaway view of magneto alternator;

Figure 2 shows that along the cutaway view of A-A line shown in Figure 1;

Magneto alternator as shown in the figure, comprise casing 10, the support 11 that is connected as a single entity with casing 10 outer bottoms, be screwed in the two end cap 2 at casing 10 two ends respectively with screw, be separately fixed at the two bearings 3 on the two end cap 2, be contained on the two bearings 3 two ends and stretch out the arbor 4 of two end cap 2 in casing 10, be fixed on stator core 6 on casing 10 internal perisporiums, stator core 6 is than the stator core length short 25% of the generator of unidimensional same model.Be pressed in the coil 7 in stator core 6 grooves, be fixed on the planchet iron 9 on the casing 10 inner segment arbors 4, be fixed on the multitudinous machine formula rotor 8 on the planchet iron 9, be screwed in the barostat 5 that is electrically connected with coil 7 on the casing 10 outer upper walls, be connected on the lead-out wire 1 on the barostat 5.

This generator amature adopts multitudinous machine formula, the length of stator core reduces, and change by the winding wire footpath, make this generator copper loss reduce, leakage field reduces, and has improved the power output of generator, when making on installing to small tractor, under the condition of equal road conditions, with the brightness of illuminating lamp strengthen, reduced accident potential.Reach the requirement of safe driving.
