Abstract

The utility model relates to the high efficiency small volume motor and dynamo structure. The structure is mainly characterized in that a stator is respectively arranged at two ends of a rotating shaft to form the double-stator structure, in addition, two magnets are arranged at a rotating shaft group between two stators to form a double-rotor. The magnet of the rotor is provided with the south polarity and the north polarity with a plurality of poles, the stator consists of silicon steel sheet and a coil. Thus, when the stator is powered on, the motor effect is formed, so that the rotating shaft of the rotor has the double-torsion (horsepower), when the rotating shaft of the rotor is rotated by an external force, the dynamo effect is formed, thereby both of two stators can generate electricity and produce the efficacy of double efficiency.

2. structure there is no any heat abstractor, and the heat energy that is produced during running is difficult to heat radiation, the louvre heat extraction that only can lean on heat loss through radiation and shell 14 rear ends, but its radiating effect is limited, and the high heat that running produces will lower efficiency and useful life.

The utility model content

The purpose of this utility model is to provide a kind of motor, electric generator structure of high efficiency small size, by two stators, two-spool effect, rotating shaft can get double torsion (horsepower) when the generator user mode, and two stators all generate electricity and get double generating efficiency when the generator user mode.

For this reason, the technical solution adopted in the utility model is: a kind of motor of high efficiency small size, electric generator structure, include stator and rotor, and be combined in the shell, wherein, described stator, comprise a pair of fixed disk, be fixedly arranged on the two ends of shell respectively, be installed with coil and silicon steel sheet on this fixed disk, form the structural form of two stators; Described rotor, comprise a rotating shaft, this rotating shaft by the bearing pivot between two fixed disks, this rotating shaft is nested with a stiffening plate, and link by a key, these stiffening plate both ends of the surface magnet that locks respectively, this magnet have the extremely magnetic of south, arctic property of number, the magnet at two ends respectively with the silicon steel sheet and the corresponding effect of coil of two ends stator.

The end face of this stiffening plate is laid with several grooves and makes that this stiffening plate and group of magnets are fashionable to be had the space and exist.

Adopt such scheme, the utility model to the energising of two stator coils, makes coil act on two magnet during as the motor start, is two stator effect rotors, and makes the rotating shaft rotation, and this rotating shaft is rotated by dual force, therefore can get the effect of double torsion (horsepower); When as the generator start, external force effect rotating shaft makes the rotation of two magnet simultaneously and acts on two silicon steel sheets, coil, forms two stators, and coil is generated electricity simultaneously, promptly is the effect that can get double generating.
