Abstract
It the utility model is related to Popular Science Education technical field, a kind of more particularly to simple interactive device for demonstrating motor principle, including casing and the table top being located on the casing, a magnet is provided with described table top to put, described magnet pendulum is made up of bearing and the spill spin block on the bearing, permanent magnet is respectively equipped with described spill spin block both ends, electromagnet using the bearing as the center of circle according to isogonism circumference array distribution around the spill spin block, described electromagnet is made up of hot-wire coil, shift knob and shield.The utility model device can control the power on/off of electromagnet by shift knob；The both ends of magnet pendulum are respectively arranged with permanent magnet, and magnet pendulum can rotate around bearing.When one end permanent magnet of magnet pendulum is close to a certain electromagnet, corresponding shift knob is clicked on, now electromagnet, which is powered, produces magnetic field, and the permanent magnet in magnetic field and magnet pendulum end interacts, so that magnet rotation moves up, here it is the principle of electric motor operation.
Description
Technical field
The present invention relates to Popular Science Education technical field, more particularly to a kind of simple interactive device for demonstrating motor principle.
Background technology
Motor principle is that people learn the more indigestible knowledge point of electricity knowledge, is occurred for this knowledge point
The teaching aid of many simple, intuitives, in the prior art, such as publication number CN 205451629U and CN204288627U is
It is designed according to the real structure of motor, although principle can be demonstrated clearly, thinking is relatively more fixed, overall table
Existing interest not enough, without interactive, allows people to lack enthusiasm in viewing.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior-art devices interactive insufficient and one kind for designing is useful in section
The simple interactive device of the interactive demonstration motor principle in skill shop.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of simple interactive device for demonstrating motor principle, including casing and the table top that is located on the casing, in institute
The table top stated is provided with a magnet and put, and described magnet pendulum is made up of bearing and the spill spin block on the bearing,
Described spill spin block both ends are respectively equipped with permanent magnet, electromagnet using the bearing as the center of circle according to isogonism circumference array distribution in institute
State around spill spin block, described electromagnet is made up of hot-wire coil, shift knob and shield.
Compared with prior art, beneficial effects of the present invention are：
A kind of simple interactive device for demonstrating motor principle of the present invention, can control electromagnet by shift knob
It is powered and powers off；The both ends of magnet pendulum are respectively arranged with permanent magnet, and magnet pendulum can rotate around bearing.When magnet pendulum one end forever
When magnet is close to a certain electromagnet, corresponding shift knob is clicked on, now electromagnet, which is powered, produces magnetic field, magnetic field and magnet pendulum end
The permanent magnet interaction in portion, so that magnet rotation moves up, when the next electromagnet of steering, and now if clicked on corresponding
Shift knob, a same active force will be produced to permanent magnet so that magnet pendulum rotating speed increase, the like, such as
Fruit all clicks on corresponding shift knob when one end that magnet is put moves to electromagnet, then the rotating speed that can put magnet is more next
It is faster, the principle of this namely motor.
Brief description of the drawings
Fig. 1 is main structure diagram of the present invention；
Fig. 2 is overlooking the structure diagram of the present invention.
Embodiment
Referring to shown in accompanying drawing 1-2, a kind of simple interactive device for demonstrating motor principle, including casing 1 and be located at described
Table top 2 on casing 1, a magnet is provided with described table top 2 and puts 3, described magnet pendulum 3 is by bearing 3-1 and is arranged on
Spill spin block 3-2 on the bearing 3-1 is formed, and is respectively equipped with permanent magnet 3-3 at described spill spin block 3-2 both ends, electromagnet 4 with
The bearing 3-1 be the center of circle according to isogonism circumference array distribution around the spill spin block 3-2, described electromagnet 4 is by being powered
Coil 4-1, shift knob 4-2 and shield 4-3 are formed.
Mode of operation and principle are：A kind of simple interactive device for demonstrating motor principle of the present invention, can pass through switch
Button 4-2 controls hot-wire coil 4-1 energization and power-off；The spill spin block 3-2 both ends of magnet pendulum 3 are respectively arranged with permanent magnet 3-
3, spill spin block 3-2 can be by rotating, when spill spin block 3-2 one end permanent magnet 3-3 is close to a certain on the bearing 3-1 that is attached thereto
During electromagnet 4, operator clicks on the shift knob 4-2 being connected with the electromagnet 4, and now electromagnet 4, which is powered, produces magnetic field, magnetic
The permanent magnet 3-3 that field puts 3 ends with magnet interacts, so that magnet pendulum 3 rotates, turns to next electromagnet 4, and
Now if operator clicks on next shift knob 4-2, a same active force will be produced to next permanent magnet 3-3
So that the rotating speed increase of magnet pendulum 3, turns to next electromagnet 4, the like, if whenever an end motion of magnet pendulum 3
During to electromagnet 4, operator clicks on corresponding shift knob 4-2, then can make that the rotating speed of magnet pendulum 3 is more and more faster, and this is also
It is the principle of motor.Patent of the present invention experiences the principle of motor principle by operator in interactive process.
It is described above, it is only the preferred embodiments of the present invention, not limits the present invention,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But it is every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
