Abstract
The utility model discloses an external rotor wind generator comprising a generator head, and is characterized in that: the generator head and generator wheel hubs are connected into a whole; a circumference of the generator head is provided with a plurality of flanges used for locating magnetic steels, the magnetic steels of the generator are fixed to the generator head through the flanges; a stator coil of the generator is arranged inside the magnetic steels; and a magnetic conductive metal casing of the generator, acting as a casing part of the generator, is sleeved outside the magnetic steels and fixedly connected with the generator head. According to the external rotor wind generator of the utility model, the casing of the generator and the magnetic steels are rotary, a main shaft and the stator coil on the main shaft are not rotary, in a power generation principle, when a relative motion occurs between a lead and the magnetic steels, the lead may cut magnetic lines to generate an electromotive force, in this way, as a rotating radius of the casing is large, for the small-sized wind generator, generating capacity generated by the external rotor can be increased obviously.
Description
[technical field]
The utility model relates to a kind of external rotor wind driven electric generator.
[background technology]
The rotor of general wind-driven generator mainly comprises the magnet steel on main shaft and the axle, and this part rotates, and a part is casing and stator winding in addition, and this part is actionless.Its fault of construction is, from electricity generating principle, lead and magnet steel have relative motion, and lead will cutting magnetic line and produced electromotive force.Because the radius of gyration is less relatively, so as far as small-sized wind power generator, the energy output of internal rotor generating is relatively low, said defective value must improve.
[utility model content]
In order to overcome the deficiency of prior art; The utility model provides a kind of external rotor wind driven electric generator; This wind-driven generator and existing wind-driven generator are just in time opposite, adopt external rotor, because the shell radius of gyration is big; So as far as small-sized wind power generator, the energy output of external rotor generating has obvious increase.
The technical scheme of the utility model is described below: a kind of external rotor wind driven electric generator; Comprise a generator head; It is characterized in that described head and generator wheel hub are linked to be an integral body, described head circumference is provided with several flanges that supplies the magnet steel location; The magnet steel of generator is realized fixing through described flange and said head; The stator coil of generator is arranged on magnet steel inside, and the magnetic conductive metal shell of generator is as the housing part of generator, and it is outside and is connected with head and realizes fixing to be enclosed within magnet steel.
According to said structure, head and magnetic conductive metal shell close-fitting are pressed into fixing, and head and generator wheel hub are linked to be an integral body, need not make wheel hub more separately, and several supply the flange of magnet steel location on the head, make magnet steel location easy to assembly, accurate.
Magnetic conductive metal shell one is to be used for fixing magnet steel, the 2nd, form magnetic field, and the adjustment outer casing thickness can conveniently be adjusted power generation performance.
According to the utility model of said structure, its beneficial effect is that the generator casing and the magnet steel of the utility model rotate; Stator coil on main shaft and the main shaft does not rotate, and from electricity generating principle, lead and magnet steel have relative motion; Lead will cutting magnetic line and is produced electromotive force; Because the shell radius of gyration is big, so as far as small-sized wind power generator, the energy output of external rotor generating has obvious increase.

[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is further described:
Like Fig. 1-shown in Figure 6; A kind of external rotor wind driven electric generator comprises a generator head 1, it is characterized in that; Described head 1 is linked to be an integral body (wheel hub is not expressed) with the generator wheel hub; Described head 1 circumference is provided with several flanges 5 that supplies magnet steel 2 location, and the magnet steel 2 of generator is realized fixing through described flange 5 and said head 1, and the stator coil 3 of generator is arranged on magnet steel 2 inside; The magnetic conductive metal shell 4 of generator is as the housing part of generator, and it is outside and is connected with head 1 and realizes fixing to be enclosed within magnet steel 2.
