Abstract
The utility model discloses a brushless regulating magnet and voltage stabilizing single-phase AC electric generator, which can be used for the small-and-medium-size independent power supply driven by gasoline engines and diesel engines. The brushless regulating magnet and voltage stabilizing single-phase AC electric generator is provided with a pair of large grooves [8] in the direction of the transversal shaft of the stator, and the internal parts of the large grooves are provided with voltage coils [6] and current coils [7] which are respectively lead into the direct current which can reflect the output voltage and the load electricity. The voltage which is lead into the voltage coils is the DC voltage that the output voltage is rectified by a bridge rectifier, and the electric current which is lead into the current coils is the direct current that the load current passes through the bridge rectification. The brushless regulating magnet and voltage stabilizing single-phase AC electric generator is suitable for the small-and-medium-size single-phase generator which requires very stable output voltage and requires the capacity of being smaller than 10 kW.
Description
The utility model is single-phase, brushless, adjustable magnetic, the voltage stabilizing alternating current generator that can be used for gasoline engine, diesel-driven medium and small independent current source.
Present employed magneto alternator is after permanent-magnet steel magnetizes, its magnetic potential just is fixed up, has nonadjustable character, so the performance of magneto alternator can not meet the demands, existing medium and small generator still adopts the mode of excitation, adjusts the size that rotor excitation current changes output voltage.Motor volume is increased.The slip-ring brush structure is arranged, poor reliability, and excitation loss decrease in efficiency.
The purpose of this utility model is to provide a kind of brushless, touchless adjustable magnetic alternating current generator that makes the stable single-phase permanent brushless of output AC voltage automatically.
The utility model is realized as follows, accompanying drawing 1 is the profile of motor, (1) is stator core stamping sheet among the figure, on the core stamping except that having at y direction the normal teeth groove, in X direction a pair of vat (8) is arranged, be embedded with single-phase winding (4) at longitudinal axis groove, the rotor body (2) and the neodymium iron boron magnetic body (3) that are made of magnetic conductor are arranged on rotor, potential winding (6) and current coil (7) are arranged in stator transverse axis vat, and both feed the direct current that reflects voltage and reflected load electric current respectively.The voltage that feeds potential winding (6) is the direct voltage after the rectification of output voltage process bridge rectifier, and the electric current that feeds current coil (7) is that load current is through the direct current behind the bridge rectifier.But the direction of both magnetic potentials is just in time opposite, is designed to promptly that both composite magnetic powers are approximately 0 when nominal load.［ 5 ］ be the rotating shaft of rotor.
This adjustable magnetic stable-voltage generator does not have brush and slip ring, is that the brushless structure does not have complicated control system again.The alternating voltage of output can be designed to three specific character curves shown in the accompanying drawing 2, smooth (9), (10) that upwarp and (11) that descend, similar compound dynamo characteristic.If seal in adjustable resistance at potential winding, or current coil incorporate into shunt resistance then output characteristic be level and smooth adjustable.
This generator is applicable to the occasion that requires the medium and small generator of the highly stable capacity of output voltage below 10kw.
Claims (2)
1, a kind of single-phase permanent brushless, adjustable magnetic voltage stabilizing alternating current generator of forming by support, stator, rotor, it is characterized in that a pair of vat [8] being arranged in the X direction of stator, potential winding [6] and current coil [7] are arranged in vat, and both feed the direct voltage and the electric current of reflection output voltage and reflected load electric current respectively.
2, single-phase permanent brushless according to claim 1, adjustable magnetic voltage stabilizing alternator, the voltage that it is characterized in that feeding potential winding is the direct voltage of output voltage behind bridge rectifier, and the direct current that feeds current coil is that load current is through the direct current behind the bridge rectifier.
