Abstract
The utility model relates to a novel permanent-magnet generator. A plurality of output terminals are arranged according to the number of turns of a generator stator winding, and the output terminal with the voltage close to the rated voltage is automatically connected with a load through a switch to achieve the purpose of voltage stabilizing, therefore the generator is an ideal novel permanent-magnet generator.
Description
Technical field
The utility model relates to a kind of novel permanent magnetic generator, especially is applicable to the permanent magnet generator of vehicle.
Background technology
At present, existing permanent magnet generator is made up of power transmission shaft, rotor, stator, generator housing.When power transmission shaft drove rotor rotation, stator just can produce electric current.But under a lot of situations, because the power rotating speed is extremely inhomogeneous, voltage is too low when causing low speed; Overtension during high speed causes loaded work piece not normal easily.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of novel permanent magnetic generator is provided, and it can not only generate electricity, and can export more stable voltage under the extremely unsettled situation of power rotating speed.The utility model is realized in the following way: the utility model comprises power transmission shaft, rotor, stator, generator housing.According to the different number of turn of stator winding several outputs are set, the voltage that the minimum output of the corresponding number of turn was exported when the output that the corresponding number of turn was maximum when minimum speed was set was the highest with rotating speed reaches rated value, and the pairing number of turn of remaining then output is set to arithmetic progression.When power rotating speed during at lowest speed, pass through switch, corresponding output and load connection that will be maximum with stator winding circle, along with rotating speed improves, by switch corresponding output and load are connected successively, the voltage that is added in like this in the load is exactly more stable voltage, and the output that is provided with according to the different numbers of turn of winding is many more, and it is steady more to connect the voltage that sends according to said method.Used switch can adopt centrifugally regulated mechanism controls, also can control by electronic device.
The utility model can make generator under the situation of rotary speed unstabilization, can both produce more stable output voltage.
Description of drawings
The vertical section structural map of Fig. 1 the utility model embodiment one.
Fig. 2 circuit theory diagrams of the present utility model.
The circuit block-diagram of Fig. 3 the utility model embodiment two.
Embodiment
The utility model embodiment now is described in detail in detail in conjunction with the accompanying drawings:
Embodiment one: as shown in Figure 1 and Figure 2, switch (2) is connected with switch (3), centrifugally regulated mechanism (11) and power transmission shaft (8) coaxial rotation, when power transmission shaft (8) rotating speed increases to output (7) output voltage and just in time exceeds rated voltage, centrifugally regulated mechanism (11) pull switch (2) disconnects with output (4), again with output (5) closure.Along with rotating speed continues to increase, when output (7) output voltage just in time surpassed rated voltage once more, centrifugally regulated mechanism (11) pull switch (3) disconnection was connected with switch (2), again with output (6) closure.When rotating speed is reduced to output (7) when output voltage is lower than rated voltage, centrifugally regulated mechanism (11) returns, switch (3) disconnects and being connected with output (6), again with switch (2) closure, when rotating speed continues to reduce, when output (7) output voltage was lower than rated voltage once more, switch (2) disconnected and being connected with output (5), again with output (4) closure.
Embodiment two: as shown in Figure 3, relay (2), relay (3), relay (4) adopt the series connection form, when output (11) output voltage just in time surpasses rated voltage, unidirectional diac (15) conducting, triggering drive circuit (12) driving relay (2) disconnection is connected with output (5), again with output (6) closure.When output (11) output voltage surpasses rated voltage once more, unidirectional diac (16) conducting, triggering drive circuit (13) driving relay (3) disconnection is connected with relay (2), again with output (7) closure.When output (11) output voltage surpasses rated voltage again, unidirectional diac (17) conducting, triggering drive circuit (17) disconnection relay (4) is connected with relay (3), again with output (8) closure.When output (11) voltage drops to rated voltage when following, unidirectional diac stop conducting, whole process is opposite with said process, makes the output voltage of output (11) stable basically.
