Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Referring to Fig. 1-4, the utility model provides a kind of brushless engine teaching training apparatus, comprise support 1, coil winding 12, rotor, bolster 8 is set on support, rotor comprises installing plate 2 and magnet 10, symmetrical setting-in two magnet 10 on installing plate 2, installing plate 2 is arranged on bolster 8 and rotates centered by bolster 8, and in installing plate 2 left and right sides, corresponding every block of magnet 10 arranges some columnar iron cores 11, on each columnar iron core 11, coil winding 12 is set, coil winding is connected to form current return, indicating lights connected in series 4 on current return.It is a kind of for simple structure, easy to operate teaching appurtenance that the utility model provides, when installing plate is rotated, magnet rotates thereupon, now, the relative magnet of coil winding, the magnetic line of force is cut, therefore, generation current in coil winding, referring to Fig. 4, when all coils windings in series, and be connected with pilot lamp on loop time, the electric current in loop can make pilot lamp luminous.Velocity of rotation with installing plate is larger, the brighter display of pilot lamp.
Support is frame-type, and bolster 8 is fixed between the munnion of both sides, is provided with multiple through holes on the munnion of both sides, and one end of columnar iron core 11, through through hole, is fixed on munnion with hexagonal nut 13.On each columnar iron core 11, coil winding 12 is set, and columnar iron core 11 also can be outside through hole stretches out support, continues to be wound around one section of coil winding, thereby make device produce larger electric current on the position outside support munnion.
Installing plate is driven by belt gear, and as shown in Figure 1, belt gear comprises driving wheel 7, engaged wheel 5 and belt 6, driving wheel center arranges wheel shaft, wheel shaft is arranged on support, one end connecting handle crank 9 of wheel shaft, and swinging handle crank 9 can make driving wheel 7 rotate.Engaged wheel 5 is connected with installing plate 2, and therefore, in the time that belt drives engaged wheel 5 to rotate, installing plate 2 synchronously rotates, and magnet 10 also circumferentially rotates thereupon, thereby, make coil winding cutting magnetic line.As shown in Figure 4, on installing plate 2, the N extreme direction of two magnet 10 is contrary.The direction of winding of the coil winding 12 arranging in installing plate 2 symmetria bilateralis is identical, when the position of the magnet on installing plate is during just just to four of the left and right sides columnar iron cores 11, according to the right-hand rule, in coil winding, produce the electric current of direction as shown by arrows, in the time that magnet continues to rotate by direction as shown, the magnetic line of force is gradually away from coil winding, current amplitude weakens, when rotation 90 is spent, its current value is the most weak, when being rotated further while spending to 180, the S of second block of magnet is the columnar iron core to right side, top extremely just, now, direction of current is contrary with direction as shown, its acrometron also reaches maximal value.In device of the present utility model, by rotatablely moving of magnet, in coil winding, produce the alternating current of sinusoidal variations, by wire, four coil winding are connected in series, and the electric light of connecting on circuit, rotates installing plate with given pace, and electric light can be luminous.In the utility model, the size of magnet is diameter 22mm, thick 10mm; Columnar iron core diameter 12mm, long 60 mm, the copper wire diameter 0.65mm of each coil winding, long 3 meters, in the time that installing plate rotates with the linear velocity of 0.8 meter per second, each coil winding can produce the no-load voltage of 0-0.8V.
As another embodiment, also can motor-driven mode replace the mode of hand crank, driving wheel center arranges wheel shaft, pair of axle spindles bearing is set on support 1, and wheel shaft is arranged on the wheel bearing of support two munnions, and one end of wheel shaft connects buncher, the output shaft of buncher connects wheel shaft, replace hand crank drive belt transmission mechanism by buncher, thereby make electric current more stable, view and emulate effect more desirable.Except the type of drive of belt gear, all the other structures are same as the previously described embodiments, do not describe one by one at this.
As another embodiment, on the basis of above-described embodiment, also can on two munnions of support, supporting shaft bearing be set, bolster 8 is arranged on supporting shaft bearing, and one end of bolster 8 connects buncher.The output shaft of buncher connects bolster, directly replaces belt gear drive installing plate to rotatablely move by buncher.All the other structures are same as the previously described embodiments, do not describe one by one at this.
Further, referring to Fig. 3, columnar iron core is separately fixed at by hexagonal nut on the both sides munnion of support, therefore, can be connected with iron plate in the outer end that is located at the columnar iron core on same munnion, on iron plate, have through hole, the position of through hole is suitable with distance and the diameter of two columnar iron cores with size, by hexagonal nut, iron plate is connected with two columnar iron cores.Increased after iron plate, be equivalent to the mass penalty of two columnar iron cores, can see, under the constant situation of other condition, the brightness of electric light increases.Thereby verify iron core mass penalty, can make magnetic flux increase, thereby electric current has increased.In when teaching, by student by stack polylith iron plate, experimental verification magnetic and electric transforming principle, the Grasping level of intensification to principle.
In practice, also can utilize the utility model device, allow student pass through the trial of the connected mode to different coil winding, learn electrical principle.
