Abstract

The utility model discloses a super-low micr permanent magnetic ac. generator which comprises a shell body and a shell cover which are coaxial and can rotate oppositely. The circumference of the shell body is uniformly distributed with permanent magnets with S poles and N poles arranged alternatively, and each permanent magnet is isolated by an isolation cover. Pole cores which are corresponding to the permanent magnets are fixed on the shell cover, and the pole cores are sheathed with coils. The generator has simple structure, and can generate electricity by using foot operation, hand operation, small wind or small water force as power.

Description

Very low speed microminiature magneto alternator

The utility model relates to a kind of small-sized electric generating apparatus.

Traditional alternating current generator is that the principle of utilizing the lead cutting magnetic line to produce electric energy is generated electricity, the fixed magnetic field of generator is produced by special winding iron core, and volume is big, and relative rotation speed is more than thousand rev/mins between stator and rotor, sine wave output, frequency are 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 requirement.

The purpose of this utility model is: a kind of very low speed microminiature magneto alternator is provided, and this electric generator structure is simple, and can ride, hand, little wind-force or small hydro generate electricity as power.

The technical solution of the utility model is: a kind of very low speed microminiature magneto alternator, it comprises coaxial, relatively turnable housing and cap, be evenly equipped with the S utmost point and N utmost point permanent magnet alternately on the circumference of described housing, isolate with cage between each permanent magnet, be fixed with on the described cap and the corresponding pole core of permanent magnet, the pole core upper sleeve through has coil.

One of technical scheme that the utility model is concrete is: a kind of very low speed microminiature magneto alternator, it comprises coaxial, relatively turnable housing and cap, be evenly equipped with the S utmost point and N utmost point permanent magnet alternately on the circumference of described housing, isolate with cage between each permanent magnet, be fixed with on the described cap and the corresponding pole core of permanent magnet, the pole core upper sleeve through has coil; Described cap is fixed on the axle sleeve by screw thread, is equipped with axle in the axle sleeve, is provided with bearing between axle and the axle sleeve, and described housing is fixed on the termination of axle by nut and positioning sleeve.

Two of the technical scheme that the utility model is concrete is: a kind of very low speed microminiature magneto alternator, it comprises coaxial, relatively turnable housing and cap, be evenly equipped with the S utmost point and N utmost point permanent magnet alternately on the circumference of described housing, isolate with cage between each permanent magnet, be fixed with on the described cap and the corresponding pole core of permanent magnet, the pole core upper sleeve through has coil; Described cap is fixed on the member, housing by nut be fixed on the axle the termination, the axle from member, penetrate, the axle and member between be provided with bearing.

In the technique scheme, described permanent magnet can have two row side by side or more than two row, be provided with divider wall between row and isolate; Described pole core also can coaxially be provided with two groups or more, is provided with slider between group and isolates.

Advantage of the present utility model is that it is simple in structure, price is low, long service life, can change various low-powers into electric energy, effectively utilizes foot-operated power, hand power, small wind and miniature hydro-power generation, satisfies the needs of different field.
