Embodiment
The mutual magnetic induction effect that produces of magnetic field and electric field is to find that by faraday (Faraday) faraday finds that when promptly conductor passed the magnetic line of force, lead can produce induced electromotive force when the conductor cutting magnetic line.
As shown in Figure 1 and Figure 2, based on above-mentioned principle, the present invention includes the coil holder 12 and the magnet arrangement 20 of induction coil 10, ccontaining induction coil 10.
Interior polar cap 122 and outer polar cap 123 differ from base 121 by being respectively equipped with the inwardly curved outer pole piece of establishing 125 of polar cap 122 directions of curved interior pole piece of establishing 124 of a plurality of outside polar cap 123 directions and plural number on the ora terminalis that pastes, and pole piece 124 and outer pole piece 125 are the staggered coil holder 12 that is arranged in and differ from the side of base 121 with formation sensitive surface 126 in making.
As shown in Figure 3, magnet arrangement 20 is the annular permanent magnnet that is made of a plurality of magnetic poles, and magnetic pole comprises the N utmost point 201 that is staggered annular array and reaches and the S utmost point 202; Magnet arrangement 20 also can be has a plurality of annular permanent magnnets that are the staggered annular array N utmost point and the S utmost point.
So, when coil holder 12 relative rotary motion of magnet arrangement 20 and ccontaining induction coil 10, the N utmost point 201 of magnet arrangement 20 and the S utmost point 202 can produce magnetic induction respectively to interior pole piece on the sensitive surface 126 124 and 125 moments of outer pole piece.Promptly when a N utmost point 201 fronts wherein to inside and outside pole piece 124,125 wherein during a pole piece, pole piece can be responded to into S polarity, in next moment, the S utmost point 202 of the contiguous N utmost point 201 rotates to just to be faced when having the pole piece of S polarity, and the S utmost point 202 can be responded to into N polarity immediately with the pole piece of sensed one-tenth S polarity; Promptly for same pole piece, so be subjected to the mutual induction repeatedly of the N utmost point 201, the S utmost point 202, become (Time variable) magnetic field in the time of just can producing, make induction coil 10 under the effect of time-varying magnetic field, produce induced electromotive force, and connect the time time-dependent current that line 11 is output as alternating current by two.
As Fig. 4, shown in Figure 5, group is established FYA windmill 30 of the present invention and is comprised handle 31 and blade 32.Handle 31 is provided with central shaft 311, and in setting firmly Ben Faken magnet arrangement 20 with central shaft 311 same side; Blade 32 is in the coil holder 12 near the ccontaining induction coil 10 of center installing the present invention, induction coil 10 and coil holder 12 are rotated with blade 32, blade 32 is provided with the LED bulb 321 that line 11 is electrically connected that connects of several and coil holder 12 inner inductive coil 10 in addition, is provided with the bearing of establishing with central shaft 311 coupling groups 33 in coil holder 12 central part groups.
During assembling, the pad 34 of suitable size is set, can keeps forming a determining deviation of axial air-gap to make magnet arrangement 20 of the present invention and sensitive surface 126 in handle 31 and 33 on bearing.So, when blade 32 rotates with the wind, can drive coil holder 12 and interior induction coil 10 thereof, produce electric currents by the magnetic induction effect in induction coil 10 and make bulb 321 luminous, to increase the effect of windmill 30 amusements with respect to magnet arrangement 20 rotations.
As shown in Figure 6, group is established cycle wheel of the present invention and is included in the crotch 42 that the appropriate location group is established the wheel hub 40 of ccontaining induction coil 10 coil holders 12 of the present invention and set firmly magnet arrangement of the present invention in relative position.
