Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1-8, the invention provides the brushless engine teaching training apparatus of a kind of many windings, comprise cabinet 1, coil winding 2, rotor, bolster 3 is set in described cabinet, rotor comprises installing plate 4 and magnet 5, the same even number magnet 5 that is evenly distributed on installing plate 4, installing plate 4 is arranged on bolster 3 and rotates centered by bolster 3, in installing plate 4 left and right sides, over against every block of magnet, pair of columnar iron core 6 is set, described coil winding 2 is set on each columnar iron core 6, some pairs of posts 7 are set on the panel of cabinet 1, going out of each coil winding 2, entering end is connected in a pairs of posts 7, on cabinet 1, be provided with load, in the present embodiment, using pilot lamp 8 as load, pilot lamp 8 is connected with some groups of coil winding 2 by wire and forms current return.The invention provides a kind ofly for simple structure, easy to operate teaching appurtenance, when installing plate is rotated, magnet rotates thereupon, now, the relative magnet of coil winding, cuts the magnetic line of force, therefore, generation current in coil winding, when some coil winding connect, form the power circuit of pilot lamp, make pilot lamp luminous, velocity of rotation with installing plate is larger, the brighter display of pilot lamp.
Cabinet 1 comprises the casing that panel, side plate, rear plate etc. surround, and the driving mechanism of coil winding 2, installing plate, installing plate is all placed on box house.The panel of cabinet comprises that the first vertical panel 11, the second panel 12, the first panels that tilt are transparent PC sheet material, can see the rotation status of installing plate 4.Binding post 7 is arranged on the second panel 12, and pilot lamp 8 is arranged on the second panel 12.Bolster 3 is fixed between cabinet biside plate, and is provided with a plurality of through holes on cabinet biside plate, and one end of columnar iron core 6, through through hole, is fixed on side plate with hexagonal nut 13.On each columnar iron core 6, coil winding 2 is set.
Installing plate 4 is driven by belt gear, as shown in Figure 1, belt gear comprises driving wheel 9, engaged wheel 10 and belt 11, driving wheel center arranges wheel shaft, the two ends of wheel shaft are arranged on the side plate of cabinet, one end connecting handle crank 14 of wheel shaft, swinging handle crank 14 can make driving wheel 9 rotate.Engaged wheel is connected with installing plate, and therefore, when belt drives engaged wheel rotation, installing plate synchronously rotates, and magnet also circumferentially rotates thereupon, thereby, make coil winding cutting magnetic line.As shown in Figure 8, on installing plate, opposite polarity directions between adjacent magnet 5, shown in figure, has been evenly arranged six magnet 5 on installing plate, by order clockwise, with the magnet pushing up most, starts, and in installing plate the same side, the polarity of magnet is respectively N-S-N-S-N-S.Corresponding six magnet, both sides at installing plate, each six columnar iron cores 6 of the every side of difference equidistant placement, numbering is respectively Q1-Q12, and wherein, Q1-Q6 is in the same side, at a time, just in time simultaneously over against six magnet on installing plate, Q7-Q12 is at opposite side, is over against six magnet on installing plate equally.According to the right-hand rule, when coil winding cutting magnetic line, in coil winding, produce the electric current of certain orientation, when we connect several coil winding in cabinet connect load in the consistent modes of current trend, just can form the power circuit of load, thereby to load, provide power supply, make its work.When installing plate rotates, make magnet 5 from when departing from columnar iron core 6 gradually, the magnetic line of force is gradually away from coil winding, and current amplitude weakens, when rotation 30 is spent, its current value is the most weak, when being rotated further while spending to 60, the S utmost point of second block of magnet is over against the columnar iron core on right side, top, now, contrary with just now of direction of current, its acrometron also reaches maximal value.In device of the present invention, by rotatablely moving of magnet, in coil winding, produce the alternating current of sinusoidal variations, by wire, some coil winding are connected in series, and the pilot lamp of connecting on circuit, rotates installing plate with given pace, and pilot lamp can be luminous.In the present invention, 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, when 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.
Referring to Fig. 6-7, the coil winding of actual training device of the present invention can realize the multi-form combination of many groups, illustrate, as we select with Q2, Q3, Q7, Q9, Q10, the coil winding of Q12 is in parallel, the winding mode of each coil winding is identical, as shown in Figure 6, the left end marker of coil winding is A, right-hand member indicates and is B, A end, B end is connected on the corresponding binding post of the second panel, on the second panel, the coil winding respectively each binding post being connected and AB end are made sign, according to the right-hand rule, we can determine the direction of current of each coil winding, thereby on the second panel, by wire by Q2, Q3, Q7, Q9, Q10, the coil winding of Q12 is connected in parallel, its mode of connection as shown in Figure 7.
If desired direct current output, series rectifier circuit on the electric power loop of load.
For the generating state of the more various modes of connection accurately, can on the electric power loop of load, connect the electrical detection facilities such as reometer, voltage table, or oscillograph.
As another embodiment, also the mode that can motor-driven mode replaces hand crank, as pair of axle spindles bearing is set on cabinet biside plate, the wheel shaft of driving wheel is arranged on wheel bearing, one end of wheel shaft connects buncher, and the output shaft of buncher connects wheel shaft, by buncher, replaces hand crank drive belt transmission mechanism, 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, at this, do not describe one by one.
As another embodiment, on the basis of above-described embodiment, also can on the biside plate of cabinet, supporting shaft bearing be set, bolster 3 is arranged on supporting shaft bearing, and one end of bolster 3 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, at this, do not describe one by one.
Further, referring to Fig. 5, columnar iron core is separately fixed at by hexagonal nut on the both sides munnion of support, and therefore, the outer end that is located at the columnar iron core on same side plate is connected with iron plate.
Can be connected with iron plate 15 in the outer end that is located at the columnar iron core 6 on same munnion, have through hole on iron plate, the position of through hole is suitable with distance and the diameter of two columnar iron cores with size, by hexagonal nut 13, 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 verified 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.
Disclosed is above only specific embodiments of the invention, does not form limiting the scope of the invention, and all changes without process creative work of doing according to technical solution of the present invention, within all should dropping on protection scope of the present invention invention.
