Abstract
The utility model provides a very low speed miniature AC permanent magnet generator which is composed of a housing member, a housing cover member and a connection structure which is connected with the housing member and the housing cover member and makes the housing member and the housing cover member rotate correspondingly, wherein, the housing member comprises an outer housing, and permanent magnets and a shielding case arranged on the inner circle of the outer housing in an interphase mode. The housing cover member comprises an outer housing cover, pole cores which are fixed on the outer housing cover and are corresponding to the permanent magnets one by one and coils sheathed on the pole cores. The utility model has simple structure, can be used as the AC generator which uses foot pedaling, hand shaking, small-sized wind power or small-sized water power as the power, and can satisfy the requirement for different regions and fields.
Description
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), particularly relates to a kind of very low speed microminiature magneto alternator.
Conventional alternator is that the principle of utilizing the lead cutting magnetic line to produce electric energy is generated electricity.The fixedly magnetic field boundary of generator is produced by special winding iron core, and volume is big, between stator and rotor relative rotation speed more than thousand rev/mins, sine wave output, frequency is the alternating voltage of 50HZ.The light fixture that travels that now is used for bicycle adopts the power supply of mill motor, its rotating speed needs more than 1500 rev/mins, it is the steamboat by large diameter wheel wheel rim friction mill motor, makes its rotary electrification, and gearratio is up to more than 30, friction loss is big, efficient is low, and physical demands is big, and wheel is had damage, when particularly road conditions are relatively poor, often can not satisfy lighting demand.
It is a kind of simple in structure that the purpose of this utility model is to provide, and is the very low speed microminiature magneto alternator that power generates electricity with foot-operated, hand, small wind or small-sized waterpower.
The utility model very low speed microminiature magneto alternator.Realize that like this it is by housing parts, the cap parts, and connect housing parts and cap parts and make its in relative rotation syndeton form.Wherein, housing parts comprises iron shell, alternate permanent magnet and the cage that is fixed on the shell inner periphery.The N utmost point and the S utmost point of permanent magnet are alternately, and promptly each permanent magnet is opposite with the magnetic polarity of adjacent permanent magnet, and permanent magnet adds up to 2 multiple, and cage is a nonmagnetic substance.The cap parts comprise casing cover, be fixed on the casing cover and with permanent magnet pole core one to one, be set on the coil on the pole core.Pole core can be fixed on the casing cover inboard by rivet, and pole core is generally T shape, and pole core is a circle distribution, and its outer diameter is slightly less than the interior circular diameter of circumference that permanent magnet becomes, and the coil that is set on the pole core is connected in series.Connection housing parts and cap parts are done in relative rotation, and syndeton is two kinds of situations, one, syndeton is a bearing, as ball bearing or other bearing etc., at this moment, the pole core mesopore of the outer ring of ball bearing and cap parts is tightly fixed, the cylindrical portion external diameter that the shell middle part of inner ring and case member extends internally is tightly fixed, rotary power is generally provided by axle and the axle sleeve installed on the equipment of the present utility model to make housing parts and cap parts do in relative rotation, during use, the end of axle sleeve is threaded with the shell centre bore, and axle passes the casing cover centre bore and fixes by nut and casing cover, can be that axle changes, axle sleeve does not change, also can be that axle does not change, axle sleeve changes, thereby drive casing cover and shell produce relative rotation.They are two years old, syndeton is that the bearing of wheel axle sleeve of the present utility model, wheel axle and wheel is installed, shell in the case member and axletree interplanting are integral, and with shell notch portion outward flanging, the circumferential aperture that is used to install vehicle wheel spoke is arranged on the flange, install wheel axle of the present utility model by fixed by nut on casing cover.Be the output easy-to-connect, wiring pile can be set on casing cover, the bonding weld tabs is set on the pole core.
The operation principle of the utility model very low speed microminiature magneto alternator is to generate electricity with the principle realization of magnetic flux size and Orientation in the coil on the continuous change pole core.During use, external force makes axle sleeve drive the case member rotation, permanent magnet magnetic flux on it is sent by the N utmost point, by the gap between permanent magnet and pole core (air gap), be delivered to pairing pole core, get back to the adjacent two permanent magnet S utmost points through the left and right sides of this pole core adjacent pole iron core and gap thereof again, form closed magnetic circuit, by that analogy, because the rotation of case member causes permanent magnet and pole core relative position constantly to change, thereby the magnetic flux size and Orientation that passes to each pole core constantly changes, the coil that is enclosed within on each pole core all produces the changing alternating voltage of size and Orientation synchronously, after the voltage stack of single coil, export by wiring pile.
The advantage of the utility model very low speed microminiature magneto alternator is simple in structure, price is low, and long service life can change various low-powers into electric energy, effectively utilize low-power as foot-operated power, hand power, small wind and miniature hydro-power generation, satisfy the needs of different field.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
