Description
Technical field
The utility model relates to Students ' Sci-tech Activities demonstration instrument, is specially a kind of direct current motor and Dyn. change demonstrator.
Background technology
Innovation is a national soul, ability of only constantly bringing forth new ideas development, the great Strategy Deciding of prospering the nation with science and education must strengthen the education of science and technology of student, the demonstration instrument of present student's out-of-class technology activities is little, the instrument that direct current motor and Dyn. can exchange use does not have at all, thus student thoroughly can not understand direct current motor and Dyn. can mutual the principles of science.
Summary of the invention
The utility model relates to Students ' Sci-tech Activities demonstration instrument, is specially a kind of direct current motor and Dyn. change demonstrator; Solve the problem without instrument exemplary DC motor and DC generation function the principles of science mutually in Students ' Sci-tech Activities, the utility model is provided.
The following technical scheme of the utility model realizes:
A kind of direct current motor and Dyn. change demonstrator, comprise base, have battery case inside base, the two poles of the earth of battery case are connected with power-line terminal; It there are battery case upper cover and gib screw, are convenient to change battery; At submounts intermediate position arrangements power switch; The both sides of position mounted motor driving reduction gear component and small machine assembly respectively in the soleplate; Device crank on gear assembly; Small machine assembly has small machine power supply external connection, its end has power supply clip; Two assembly travelling belts (13) are connected; At each one of the red and green luminous diode of the top device of base plate, the electrode crossing of red and green luminous diode is connected on diode power source binding post.
The utility model can also inspire the drive of a guiding student discarded radio cassette player to reequip, and is not only beneficial to environmental protection, and demonstrating effect vivid and interesting, and practicality and generalization are very high.

Embodiment
A kind of direct current motor and Dyn. change demonstrator, it is characterized in that comprising base (1), there is battery case (10) base (1) the inside, and the two poles of the earth of battery case (10) are connected with power-line terminal (3); There are battery case upper cover and gib screw (12) thereon, are convenient to change battery; At submounts intermediate position arrangements power switch (2); Both sides, centre position mounted motor driving reduction gear component (5) and the small machine assembly (9) respectively of base plate (6); The upper device crank (4) of gear assembly (5); Small machine assembly (9) has small machine power supply external connection (11), its end has power supply clip; Two assembly travelling belts (13) are connected; At each one of the red and green luminous diode of top device (7) of base plate (6), the electrode crossing of red and green luminous diode (7) is connected on diode power source binding post (8).
Experimental demonstration method is as follows:
1, direct current motor experiment: small machine power supply external connection (11) is connected on respectively on battery case (10) two power-line terminals (3) on base (1), turn on the power switch (2), the upper small machine of small machine assembly (9) will rotate, and drives the pinion rotation of reduction gear component (5) by travelling belt drive motor.Again the reversal connection of small machine power supply external connection, direction of current is anti-, and gear is reverse rotation thereupon also.
Dyn. is tested: be connected on by small machine power supply external connection (11) on the diode power source binding post (8) of top, shake (4) with hand, red light emitting diodes (7) is on one side shinny, oppositely shake again, direction of current changes, and the green LED (7) of another side is shinny.
