Abstract
A high-power hand-operated three-phase AC generator includes a handle, a handle fixed plate, a driven gear, a press mounting gear, and a generator box body. The generator box body includes a permanent magnet, a coil, a motherboard, a PCB circuit board, a shell, a shaft, a bearing, a pad and several screws. The handle is installed on the press mounting gear through the handle fixed plate, and the press mounting gear is installed on the shell through the handle fixed plate. The diameter of the driven gear is smaller than that of the press mounting gear, and the driven gear is fixed at the middle part of the shell through a shaft. The shell forms the generator box body with the motherboard through several screws. The PCB circuit board is installed on the motherboard. The shaft is installed on the bearing which is fixed on the motherboard through several screws, and a pad is installed at the bottom of the bearing, so as to avoid the motherboard from directly generating friction between the shaft and to increase the service life. The permanent magnet surrounding coil is installed around the inner wall of the shell, the coil surrounding bearing is installed in the generator box body through several screws.
Description
Technical field
The present invention relates to a kind of generator, refer more particularly to the high power hand-operated three-phase alternating generator that a kind of product such as broadcast receiver, flashlight that can be used for storage battery is done charge power supply.
Background technology
Now be used to product such as broadcast receiver, flashlight with storage battery on the market and make the hand generator of charge power supply, this series products power output is little, and the about P=2～10W of its power (rotating speed 3000rpm) has characteristics such as volume is big, thickness is big.And its scope of application is more single than religion, generally is cannot do DC power supply to use.
Summary of the invention
The object of the present invention is to provide a kind of high power hand-operated three-phase alternating generator.It has the big characteristics of power to this high power hand-operated three-phase alternating generator with respect to existing hand generator, its power output P＞20W (rotating speed 3000rpm).The present invention not only has high-power characteristics but also its volume is little, thin thickness, its three-phase power output are directly proportional with rotor speed, alternating voltage, the electric current of this generator output
After over commutation and filtering, also can do DC power supply and use.
A kind of high power hand-operated three-phase alternating generator, it comprises that a handgrip, a handgrip fixed head, a driven gear, press-fit gear, a generator casing.Draw together in this casing and comprise a permanent magnet, a coil, a base plate, a PCB circuit board, a shell, one, a bearing, a pad, some screws.This handgrip is installed in by the handgrip fixed head and press-fits on the gear, and this press-fits gear and also is installed on the shell by the handgrip fixed head.The diameter of this driven gear will be much smaller than the diameter that press-fits gear, and this driven gear is by a middle part that is fixed on shell, this driven gear with press-fit gear and remain on same plane and intermesh.This shell is by some screws and the fixing casing that forms generator of base plate.This PCB circuit board is installed on the base plate.This axle is installed on the bearing, and this bearing is fixed on the base plate by some screws, and in the bottom of this bearing one pad is installed, and avoids base plate and axle directly to produce friction, to increase the service life.This permanent magnet around coil be installed in outer casing inner wall around, this coil is installed in the casing of generator by some screws around bearing.
Its operation principle is as follows: when hand handgrip, the gear driven driven gear that press-fits that is installed together with handgrip rotates, because this press-fits the diameter of the diameter of gear much larger than driven gear, press-fit gear rotate a circle quite and driven gear rotate some circles, under the slow-speed of revolution, can drive driven gear and rotate faster so it press-fits gear, this driven gear rotation can drive axle also can drive coil rotation generating with the bearing rotation while, and this electric energy can be done charging to products such as the broadcast receiver of being with storage battery, flashlights by the output of PCB circuit board.
