Abstract
The utility model provides a Neodymium-Ferroboron voltage-adjustable automotive alternator composed of a housing, a stator and a rotor. The inner side face of the stator silicon chip of the stator is provided with two sets of stator windings in interphase arrangement, wherein, one set of the stator windings is a regulating winding whose extension circuit passes through a voltage regulator. The rotor is composed of a rotor shaft, two disc-shaped rotor magnetic Neodymium-Ferroborons arranged on the rotor shaft as well as two rotor magnetic claws arranged on the positive and the reverse disc sides of each of the rotor magnetic Neodymium-Ferroborons. The rotor shaft is fixed on the housing of the alternator through bearings. The utility model can enable the alternator to reach the effect of high speed generation during low speed operation with adjustable voltage.
Description
The utility model relates to a kind of motor generator, but especially a kind of neodymium iron boron pressure regulator motor-car alternating current generator.
Existing motor generator has two kinds, a kind of is DC generator, it is by using electromagnet as the rotor field, power to rotor by extraneous electric current, make the coil winding generating of the magnetic force line cutting stator in this magnetic field, this generator can make rotor produce high-intensity magnetic field, and can adjust the voltage of generator by adjusting rotor current, but it will consume outer power supply stream, needs storage battery power supply, causes this machine big energy-consuming, volume is big, efficient is low.Another kind is a kind of magneto alternator, though its rotor need not consume extraneous electric current, and make with general permanent magnet, but the magnetic field intensity that permanent magnetic material produced of these low energy products is limited, so a little less than the magnetic line of force of cutting stator winding, energy output is little, and power consumption is high, and have can't regulation voltage major defect.
The purpose of this utility model is to provide a kind of permanent magnetic material of high energy product that adopts to do rotor and magnetic energy is provided, but the coil winding of stator is made the coil winding of pressure-adjusting type, but can make generator be issued to the neodymium iron boron pressure regulator motor-car alternating current generator of the effect of generating electricity at a high speed at low-speed running.
The mode that the utility model is realized is that it is by casing, stator and rotor constitute, its stator is located in the casing, the medial surface of the stator silicon chip of stator is provided with 2 groups of stator windings alternately, wherein one group of stator winding is the pressure regulation winding, the external circuit of pressure regulation winding is through voltage regulator, its rotor is located at the center in the stator, rotor is by an armature spindle and is located at 2 discoidal rotor magnet neodymium iron borons on the armature spindle and just is being located at the rotor magnet neodymium iron boron, 2 rotor magnetic pawls on anti-two cards constitute, it is N utmost point magnetic pawl that rotor magnetic pawl is respectively one, one is S utmost point magnetic pawl, N, the pawl of S utmost point magnetic pawl alternately, armature spindle by bearing fixing on the casing of generator.
Advantage of the present utility model is that rotor magnet has adopted the NdFeB material with high magnetic energy, so under low-speed running, can reach the effect of generating at a high speed, again owing to be provided with one group of pressure regulation winding in the stator winding of stator, pressure regulation winding external circuit is through voltage regulator, the energy automatic Regulation is limited to below the 150V voltage of locomotive generator.
