Description
Technical field
The utility model belongs to teaching aid technical field, particularly relates to a kind of motor principle of work demonstrating model.
Background technology
Motor all can be used in a lot of industrial and mining enterprises, and motor there will be fault in long operation process, machine maintenance workman in factory just will overhaul motor, and the employee of new registration is not when clearly recognizing the principle of work of motor, just be difficult to the place accurately finding problem, also the benefit of factory can be had influence on, in addition, during senior middle school physics teaching and university's electromechanical speciality are imparted knowledge to students, also the principle of work of Students ' Learning and grasp motor is needed, traditional teaching pattern is exactly that the combination of picture and word on textbook is to tell about the principle of work of motor, Students ' Learning gets up painstakingly, current existing electromotor teaching model, the structure of motor can only be shown, cannot the principle of work of demonstrating electrical motivation, the quality of instruction of teacher is not high yet, in order to the principle of work telling about motor of simple, intuitive, student is enable to learn the principle of work of motor fast and accurately, just need to provide a kind of demonstrating model, the workload of teacher can be alleviated, also can be intuitively, the principle of work of the explanation motor of simple and clear.
Summary of the invention
The purpose of this utility model is the combination of just word and picture in the educational engineering of solution prior art motor principle, be not easy to the problem that student understands, and the principle of work that a kind of structure is simple, reasonable in design, can show motor is intuitively provided, be convenient to student understand, improve the work efficiency of teacher, the motor principle of work demonstrating model motivated students' interest in learning.
The technical scheme that the utility model adopts is:
A kind of motor principle of work demonstrating model, comprise base, be fixedly connected on the framework on base, described base center is connected with a first plastics rotating shaft by bearing, described first center, plastics rotating shaft upper surface is fixedly connected with first U magnet, described first U magnet is vertically arranged and opening upwards, first U magnet is fixedly connected in the first plastics rotating shaft by the first clamping plate be positioned at inside its arc tips by described first U magnet, the crossbeam of described framework is connected with a second plastics rotating shaft by bearing, described second plastics rotating shaft be positioned at crossbeam below and with the first plastics rotating shaft just to setting, described second center, plastics rotating shaft bottom surface is fixedly connected with second U magnet, described second U magnet vertically arranges and Open Side Down, second U-shaped magnet is fixedly connected in the second plastics rotating shaft by the second clamping plate be positioned at inside its arc tips by described second U magnet, the first described U magnet and the second U magnet are non-contacting.
As optimization, the first described U magnet opening inside diameter is greater than the opening external diameter of the second U magnet.Further, two free ends of the second described U magnet extend to two free end inside of the first U magnet, and this physical arrangement is closer to the stator coil of true motor and rotor winding structure.
The beneficial effects of the utility model are: owing to have employed the combined demonstrating model structure of two U magnets, when stirring a U magnet with hand and rotating, the magnetic field of rotation can be produced, another U-shaped magnet also can along with rotation under rotating magnetic field magnetic fields, rotating magnetic field is produced after this process simulation stator coils of motor indirect current, the principle that rotor driven rotates, explain the principle of work of motor intuitively, there is structure simple, reasonable in design, the principle of work of motor can be shown intuitively, be convenient to student understand, improve the work efficiency of teacher, motivate students' interest in learning.
Accompanying drawing explanation
The structural representation of a kind of motor principle of work demonstrating model that Fig. 1 provides for the utility model.
In figure: 1, base; 2, framework; 3, the first plastics rotating shaft; 4, the first U magnet; 5, the first clamping plate; 6, the second plastics rotating shaft; 7, the second U magnet; 8, the second clamping plate; 21, crossbeam.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
A kind of motor principle of work demonstrating model, comprise base 1, be fixedly connected on the framework 2 on base 1, be positioned at base 1 center and be connected with a first plastics rotating shaft 3 by bearing, first center, plastics rotating shaft 3 upper surface is fixedly connected with first U magnet 4, first U magnet 4 is vertically arranged and opening upwards, first U magnet 4 is fixedly connected in the first plastics rotating shaft 3 by the first clamping plate 5 be positioned at inside its arc tips by the first U magnet 4, the crossbeam 21 of framework 2 is connected with a second plastics rotating shaft 6 by bearing, second plastics rotating shaft 6 be positioned at crossbeam below and with the first plastics rotating shaft 3 just to setting, second plastics rotating shaft 6 bottom center position is fixedly connected with second U magnet 7, second U magnet 7 vertically arranges and Open Side Down, second U-shaped magnet 7 is fixedly connected in the second plastics rotating shaft 6 by the second clamping plate 8 be positioned at inside its arc tips by the second U magnet 7, first U magnet 4 and the second U magnet 7 are non-contacting, as optimization, the first U magnet 4 opening inside diameter is greater than the opening external diameter of the second U magnet 7, further, two free ends of the second U magnet 7 extend to two free end inside of the first U magnet 4.
During concrete use, only the first U magnet need be rotated by external force, the second U magnet just also and then rotates under magnetic fields, produces rotating magnetic field after this process simulation stator coils of motor indirect current, the principle that rotor driven rotates, the principle of work of lively demonstrating electrical motivation, structure is simple, reasonable in design, the principle of work of motor can be shown intuitively, be convenient to student understand, improve the work efficiency of teacher, motivate students' interest in learning.
