Description
Technical field
The utility model relates to a kind of classroom instruction instrument, is specifically related to a kind of electromotor teaching model.
Background technology
Interaction between electromagnetic field and electric current is an important knowledge point, in the physics teaching in middle school, is absolutely necessary.Because electromagnetism is difficult to directly observe by naked eyes, be therefore all to demonstrate by instruments used for education, and electromotor teaching model is exactly one of them.Magnet in existing electromotor teaching model is all to adopt U-shaped permanent magnet, and shape is difficult to change, and cannot demonstrate electromagnetic action under different magnetic field.In addition, in classroom, teacher, when carrying out relevant electrophysics experimental demonstration, generally can only arrange corresponding experiment teaching aid on dais at present, and due to the relation at visual angle, students is difficult to see clearly specific operation process and wiring, affects teaching efficiency.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of contact reliable, long-lived lamp socket teaching aid.
For achieving the above object, the utility model provides following technical scheme: a kind of motor model, comprise substrate, rotor, magnet, it is characterized in that: before and after on described substrate, be provided with a pair of bearing, described rotor center is equipped with rotating shaft, described rotating shaft is arranged on the bearing of front and back rotationally, on described substrate, be also provided with a pairs of posts, described rotating shaft is provided with commutator, described commutator is connected with epitrochanterian winding, the both sides of the above commutator of substrate are respectively equipped with the brush that a conductive reed forms, described brush one end contacts with described commutator, the other end is fixed on substrate, and be electrically connected to a described pairs of posts respectively, described rotor both sides are respectively equipped with magnetic conductive part, described magnetic conductive part is converted into by strip tagger, the upper end of described rotor both sides magnetic conductive part is provided with permanent magnet.In the utility model, in described rotor both sides, be respectively equipped with the magnetic conductive part being converted into by strip tagger, therefore can be converted into as requested the shape needing, conveniently carry out different experiments.
The utility model further arranges: described binding post comprises conductive pole and set nut, described lock-screw comprises insulation button, on insulation button, be fixed with contact screw, conductive pole upper surface is provided with the screw matching with screw, described lock-screw is threaded with conductive pole, and partially conductive post is exposed at outside upper surface of base plate.By the setting of above-mentioned conductive pole, connect wire and both can screw and compress connection with lock-screw, for the wire that is provided with clip, can directly by being clipped on the conductive pole being exposed at outside upper surface of base plate, forming and be electrically connected to, very convenient.
The utility model further arranges again: described substrate is cuboid, and side is provided with permanent magnet.Owing to being all provided with iron plate in the blackboard of present many schools, in substrate side surfaces, be provided with after permanent magnet, electromotor teaching model can directly adsorb on blackboard, is very easy to the observation of student to experimentation, is conducive to improve teaching efficiency.
The utility model further arranges again: described rotating shaft one end can also be provided with impeller.Can be more convenient for like this observing the situation of motor rotation.
Below in conjunction with accompanying drawing, the utility model is further described.
