Abstract
The utility model relates to an auto-controlled voltage stabilization generator, which comprises a rotor and a stator, wherein, the rotor and a casing are integrated into a whole; the upper circumference of a ring-shaped rotor bracket is provided with a rotor permanent magnet; the upper circumference of the ring-shaped rotor bracket is fixed on the inside wall of the casing; the rotor permanent magnet is tightened by a non closed ring elastic ring on the rotor bracket; both sides of the ring edge of the non closed ring elastic ring are provided with inward flangings. When the rotating speed of the generator rotor is increased, because of the centrifugal force of the permanent magnet arranged on the rotor bracket being increased, the utility model overcomes the defect that the tightening force of the non closed ring elastic ring carries out radial outward displacement and the purpose of auto-controlled voltage stabilization is achieved through increasing the air gap between the stator and the rotor and limiting voltage to rise. The utility model has the advantages of simple structure, reliable work, low cost, and convenient maintenance.
Description
The utility model relates to a kind of through improved automobile-use automatic voltage regulation generator.
Directly start the motorcycle of engine retrofire or the direct powered lighting of alternator for vehicle power supply with the alternator for vehicle power supply, tractor etc., because engine is in starting, idling and cruising different operating state, its rotation speed change differs greatly, the voltage height great disparity that causes generator output, special motorcycle by foot pedal starting, during cruising generating function output normal ignition voltage, the ignition voltage deficiency of foot pedal starting often, same lighting voltage also changes because of the speed of engine rotating speed, silent when bright when causing the illuminating lamp of generator powered, influence illuminating effect.
The purpose of this utility model provides a kind ofly through improved automatic control stable-voltage generator, and it can change and output voltage is adjusted in automatic control with power rotating speed speed, and deboost raise when rotating speed was fast, thereby reached voltage stabilizing.
The purpose of this utility model is achieved in that a kind of automatic control stable-voltage generator, comprises rotor and stator, rotor and casing one, on the ring-shaped rotor support that the casing madial wall is fixed, garden week is settled rotor permanent magnet, and non-closed ring elastic ring banding rotor permanent magnet is on rotor field spider; There is inside flanging on the circle limit, both sides of non-closed ring elastic ring; On the ring-shaped rotor support, the axial isolation baffle plate is set by size, the quantity of rotor permanent magnet.
Adopt the automatic control variable-voltage generator of this spline structure, output voltage design during its power low speed transmission is on the rated value and illumination rated voltage of ignition voltage, when the power rotating speed improves, when making the rotor speed raising of generator, permanent magnet on the rotor field spider, because rotating speed improves the centrifugal force that is increased, the lock ring that makes permanent magnet overcome non-closed ring elastic ring is done radially centrifugal moving.Although spinner velocity has a more substantial increase like this, the air gap between stator and the rotor increases, and rotating speed is high more, and air gap is big more, has so just limited because rotating speed improves the rising of generator output voltage.After rotating speed reduced, the clamping force of non-closed ring elastic ring was during greater than permanent magnet centrifugal force, permanent magnet again by lock ring on rotor field spider, can still keep exporting enough voltage.Air gap between employing stator and the rotor changes the automatic voltage regulation generator of structure with the rotating speed direct ratio, has specification simple in structure, as not change original generator, reliable operation, advantage with low cost, easy to maintenance are applicable to motorcycle, hand tractor and various by the motor vehicle mains lighting supply of generator powered and the usefulness of power starting ignition power supply.
The drawing explanation of accompanying drawing.
Fig. 1 is the utility model automatic voltage regulation generator Structure profile.
Fig. 2 is the cutaway view of Fig. 1 along A-A ' line.
Fig. 1, shown in Figure 2, the stator of automatic control stable-voltage generator (2) is one and is formed by stacking by the silicon steel sheet punching press, stator core with central shaft hole, coil windings is arranged on the iron core, stator (2) can be fixed on the engine by securing member, armature spindle (6) is by the central shaft hole and concentric connection of casing (1) of stator core, fixing ring-type rotor field spider (4) on the casing madial wall, it in the ring of support stator (2), the arc length that annular support (4) is gone up by magnet (3) is provided with axial tabula plate washer, permanent magnet (3) is placed in respectively on the rotor field spider (4) of being located by diaphragm plate, nonocclusive annular resilient collar (5) will be along permanent magnet (3) banding of arranging in rotor field spider garden week on rotor field spider (4).The circle of nonocclusive annular resilient collar (5) is wide to be equated with the permanent magnet width, and there is inside flanging on the circle limit, both sides of elastic ring (5), both can increase the rigidity of elastic ring, swings in the time of preventing the magnet fast rotational again.
