Abstract
The invention discloses an electromagnetic induction experiment teaching aid comprising a first direct current motor and a second direct current motor, wherein rotor parts of the first direct current motor and the second direct current motor are connected, a wiring end of the first direct current motor is connected with a conversion joint, a wiring end of the second direct current motor is connected with two LED (Light-Emitting Diode) lamps connected in parallel, the conversion joint is connected with a controller, and the controller is respectively connected with a solar cell panel and a storage cell. When in use, the electromagnetic induction experiment teaching aid can be powered by electric energy generated by the solar cell panel, thereby achieving the advantage of environmental protection; the first direct current motor is electrified through the conversion joint to enable the rotor thereof to rotate, and the rotor of the second direct motor is simultaneously driven to rotate, so that the second direct current motor can induce the current to enable one of the LED lamps to emit light; and when the polarity is changed through the conversion joint, the rotating direction of the rotors can be changed accordingly, and the other LED lamp emits light. The experiment process is very visual, and the teaching aid has a simple entire structure and is flexible and reliable in actions.
Description
Technical field
The present invention relates to a kind of experiment teaching aid, particularly a kind of electromagnetic induction experiment teaching aid.
Background technology
Not directly perceived to the used teaching aid of electromagnetic induction experiment in teaching at present, and be to utilize civil power to operate, whether the solenoid of observing energising rocks the effect of metal bar and shows electromagnetic induction phenomenon.
Summary of the invention
The purpose of this invention is to provide a kind ofly observe obviously, flexible movements are reliable and the electromagnetic induction experiment teaching aid that utilizes sun power to experimentize, overcome the deficiencies in the prior art.
Electromagnetic induction experiment teaching aid of the present invention, comprise first direct current generator and second direct current generator that rotor portion joins, the terminals and the X-over of first direct current generator join, the terminals of second direct current generator join with two LED lamps in parallel, described X-over and controller join, and controller joins with solar panel and accumulator respectively.
Electromagnetic induction experiment teaching aid of the present invention, the electric energy that can utilize solar panel to produce during use carries out, advantage with environmental protection, give the energising of first direct current generator by the conversion connection-peg, its rotor rotation, drive second rotor DC machine simultaneously and rotate, second direct current generator can induce electric current makes one of them LED lamp luminous; Change polarity chron by the conversion connection-peg, the rotor rotation direction changes thereupon, and another LED lamp is luminous.Experimentation is very directly perceived, and this teaching aid one-piece construction is simple, and flexible movements are reliable.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Embodiment
As shown in Figure 1: 1 is solar panel, and 2 is controller, and 7 is accumulator.Solar panel 1 joins with controller 2, and controller 2 joins with accumulator 7.
4 is first direct current generator, and 6 is second direct current generator, and the rotor of the rotor of first direct current generator 4 and second direct current generator 6 joins by web member 5, and web member 5 can be the simple structure of cover, rotates simultaneously to guarantee two rotors.
8 is a LED lamp, and 9 is the 2nd LED lamp, two LED lamp reverse parallel connections and join by switch with the terminals of second direct current generator 6.
Join by X-over 3 between the terminals of first direct current generator 4 and the controller 2, can change by X-over 3 utmost point that feeds first direct current generator 4 to.
The electric energy that can utilize solar panel 1 to produce during use carries out, advantage with environmental protection, give first direct current generator 4 energisings by conversion connection-peg 3, its rotor rotation, drive the rotor rotation of second direct current generator 6 simultaneously, second direct current generator 6 can induce electric current makes one of them LED lamp luminous; Change polarity chron by conversion connection-peg 3, the rotor rotation direction changes thereupon, and another LED lamp is luminous.Experimentation is very directly perceived, and this teaching aid one-piece construction is simple, and flexible movements are reliable.
