Abstract
The utility model provides a multifunctional vertical motor model, relating to a motor model which utilizes an oblong coil supported on a stationary supporting shaft as a rotor. The motor model of the utility model is composed of a stator part and a rotor part, wherein, the stator part is composed of a magnetic shoe and a magnet; the rotor part is composed of the oblong coil and a detachable slide-ring commutator, and is hung and supported at the center of the stator part by the supporting shaft fixed on a bottom plate. The utility model has the advantages of easy assembly and disassembly, and the utility model can satisfy students to carry out the experiments for a DC motor, an AC motor, a DC electrical motor, an Oersted experiment, the action of magnetic field to electric current and electromagnetic induction experiment.
Description
The utility model relates to the motor model that uses in the physics teaching in secondary school, particularly the motor model of vertical type multifunctional.
The motor model that uses in the teaching, rotor mostly are horizontal magnetic pole types, and the student was inconvenient to observe when the teacher demonstrated, and are not easy during student experimenting to understand, and function singleness, power consumption is big, and is not quick detachable, be difficult for assembling, can not satisfy the student and start to test, improve the needs of experimental skill.
The purpose of this utility model is: design a kind of motor model opposite with prior art.It is rotor that this motor model adopts vertical square frame coil, and slip ring and commutator combine, fixed minute body structure of back shaft.Reach a tractor serves several purposes, economize the material power saving, help student's disassembly and assembly, the purpose of observation experiment.
The utility model purpose adopts following structure to realize that motor model of the present utility model is made up of stator and rotor two parts: the magnetic shoe of stationary part is designed to the garden arc, and the magnetic shoe lower end is screwed on base plate, and the magnet that magnetizes magnetic shoe is being held in the mouth in the magnetic shoe upper end.The coil design rectangularity of rotor portion is made of magazine and coil and demountable slip ring commutator in framework.And by the central authorities of the back shaft sling that passes the axle sleeve support rotor part in the slip ring commutator at stationary part.When transferring brush to contact, stir coil with hand with slip ring, can output AC; When regulating brush and contacting, stir coil with hand with commutator, can output DC; When brush contacts with commutator, and by the screw place input dc power of fixed brush, coil will rotate, and the rectangular coil of having dismantled the slip ring commutator is hung, can also demonstrate the oersted experiment, magnetic field is to the effect and the electromagnetic induction experiment of electric current.
Effect of the present utility model is very remarkable: because to have adopted vertical square frame coil is rotor, readily removable, easy dress, friction are little, and the right-hand man's rule that is used for explaining Principle of Electric Engine is very convenient; Owing to adopted the slip ring commutator to combine, reached a tractor serves several purposes; Owing to adopted coil and the split of slip ring commutator, it is multi-functional that this model has been possessed.
The drawing explanation:
Accompanying drawing is the structural representation of vertical type multifunctional motor model
Further specify the utility model below in conjunction with accompanying drawing.
As shown in drawings: the magnetic shoe 2 of stationary part is designed to the garden arc, is fixed on the base plate 19 with screw 17, and magnet 1 is being held in the mouth at the top of magnetic shoe 2.The coil 4 of rotor portion is designed to rectangle.Two the end of a thread of the lead that coil is 4 li (among the figure draw) respectively be fixed on coil 4 on screw 9 link to each other with 10.Slip ring commutator 11 and 12 is fixedly mounted on downwards and upwards respectively on the axle sleeve 6 of T font, and by screw 9 and 10 and coil 4 zoariums or split.Slip ring commutator 11 is linked to each other with screw 9 by wiring 8, and slip ring commutator 12 is linked to each other with screw 10 by wiring 7.Whole rotor portion is by being fixed on back shaft 5 slings on the base plate 19 with screw 18 on support cap 3.Brush 13 is fixed on the end root 19 by screw 16, and brush 14 is fixed on the base plate 19 by screw 15.
Regulating brush 13 contacts with the top slip ring of slip ring commutator 11, regulating brush 14 contacts with the bottom slip ring of slip ring commutator 12, stir coil 4 with hand, alternating current will be demonstrated in the sensitive galvanometer that links to each other with 16 with screw 15 (drawing among the figure), the principle that alternating current produces can be used for illustrating; Regulating brush 13 contacts with the bottom commutator of slip ring commutator 11, regulating brush 14 contacts with the top commutator of slip ring commutator 12, stir coil 4 with hand, and will demonstrate direct current in screw 15 and the sensitive galvanometer that 16 link to each other, can be used for illustrating the principle that direct current produces; Keep brush 13 and 14 to contact, and from quick-fried nail 15 and 16 input dc powers, coil 4 will rotate, and can be used for illustrating the principle of work of direct current motor with the commutator of slip ring commutator 11 and 12; The coil 4 of having dismantled T font axle sleeve 6 and slip ring commutator 11,12 is suspended on the iron stand (not drawing among the figure), again by screw 9 and 10 input dc powers, being placed on coil 4 small magnetic needle (drawing among the figure) on every side will turn to, can be used for explaining the oersted experiment, change small magnetic needle into magnet 1, the coil 4 of the energising of hanging will move, and can be used for explaining the effect of magnetic field to electric current.Screw on the coil 49 and 10 is connected with sensitive galvanometer.And allow the magnetic line of force around the coil that hanging 4 septum magnets 1.Just there is electric current to show in the sensitive galvanometer, can be used for explaining electromagnetic induction phenomenon.
