Abstract
The utility model relates to an alternate current generator, which comprises a front casing body and a back casing body. A rotor shaft having two ends stretched outwards is arranged inside an inner cavity formed by the front casing body and the back casing body, and a pair of butt jointed claw poles is sleeved on the inner section of the rotor shaft. A stator is fixed and connected at the inner ends of the front casing body and the back casing body, and the stator comprises stator cores uniformly distributed with spacing on a periphery surface and three groups of sensing coils winded on the stator core. At the stretching part of the rotor shaft, a fan wheel is arranged at one end, a belt pulley is arranged at the other end, and a permanent magnet excitation source and an electromagnetic excitation source are arranged inside the inner cavity formed by a pair of claw poles. The assembled excitation alternate current generator is arranged on a tractor, when the tractor operates at the low speed and turns, the light still shines, and the battery can also be charged.
Description
Technical field
The utility model relates to alternating current generator, more is relevant to the alternating current generator of middle-size and small-size tractor illumination charging usefulness.
Background technology
At present, the illuminating alternating current generator of installing on the middle-size and small-size tractor, mostly be magneto alternator, comprise procapsid and back casing, in procapsid and the formed inner chamber of back casing, the overhanging armature spindle in two ends is housed, be sleeved on and transfer to a pair of pawl utmost point that axle is gone up and docked, with procapsid and the affixed stator of back casing, the permanent magnet excitation source that its excitatory mode has only permanent magnet to produce, be applicable on the little tractor of engine speed change, when its weak point is generator work, the induced electromotive force that this permanent magnet excitation source is produced is low, energy output is little, advance at low-speed tractor, illuminating lamp does not work during turning, be unfavorable for safety traffic, can not be used for the electricity starting.
Summary of the invention
The purpose of this utility model provides and a kind ofly advances at low-speed tractor, illuminating lamp is still bright when turning, and can be used for the excited combinably alternating current generator of electricity starting.
This excited combinably alternating current generator, comprise procapsid and back casing, in procapsid and the formed inner chamber of back casing, the overhanging armature spindle in two ends is housed, be set with a pair of pawl utmost point of butt joint on the armature spindle inner segment, the inner at procapsid and back casing is connected with stator, stator is included on the periphery stator core uniformly at intervals and is wrapped in three groups of induction coils on this stator core, extension at armature spindle, one end is set with fan wheel, the other end is set with belt pulley, and its design feature is to be provided with permanent magnet excitation source and electromagnetism excitation source in the extremely formed inner chamber of a pair of pawl.
Above-mentioned permanent magnet excitation source is the magnet ring that is sleeved on the high permeability on the armature spindle, the electromagnetism excitation source is the magnetizing coil that is wrapped on the pawl utmost point inner convex platform, magnetizing coil constitutes with slip ring on being sleeved on the armature spindle inner segment and is electrically connected, slip ring contacts with carbon brush, carbon brush is connected with procapsid by brush holder, is equipped with induction coil to constitute the three-phase rectifier that is electrically connected in procapsid and the formed inner chamber of back casing.
The magnet ring of above-mentioned high permeability is a rubidium iron boron magnet ring.
This excited combinably alternating current generator, both can be during work without battery, by the independent excitatory generating of permanent magnetism magnetic source, can send into the dc magnetizing electric current by carbon brush and slip ring to magnetizing coil by battery again, generate electricity with the identical stack magnetic field of direction that permanent magnet excitation source and electromagnetism excitation source are produced, at this moment, the induction coil of stator is in this stack magnetic field, when driving the armature spindle rotation by belt pulley by engine, the induction coil cutting magnetic line, produce induced electromotive force, this induced electromotive force becomes direct current by the three-phase rectifier rectification, for the tractor illumination with to charge in batteries.
From the above mentioned, excited combinably alternating current generator of the present utility model, be to utilize permanent magnet excitation source and these two magnetic sources of electromagnetism excitation source to generate electricity, magnetic resistance is little, the energy output foot even tractor is advanced at low speed, can guarantee also when turning that illuminating lamp is enough bright, helps safety traffic, and can be to battery charge, be particularly suitable for the electricity starting and be engaged on the middle-size and small-size tractor of transportation and use.
