Solar Freaks

Olá,
If I build the up scheme,
the engine only starts up when the voltage reaches the value of 8V or more, right?
This scheme will not cause the engine only work with a minimum voltage of 8V?
When the capacitor discharge the current is not greater than 600mA?
with this scheme the power transferred to the engine will not be a minimum of 4.8 W (0.6 A X 8V)?

I would like to know your opinion about the functioning of this scheme.
And if it was better to put only the engine and the panel or the diagram.

greetings from Portugal

Hello,

From what i can see, sorry to say, your system will fail.

Your right about 1 thing though, the motor will only operate when voltage exceeds 8 volts, as that is the breakdown voltage of the zenner. Your zenner would be burning off the 8 volts, and your motor will get the excess.

Using that particular methodology would similar to using a 7 volt, 600mA panel instead of your 15v panel.

I got it!
And is there any way to put a FET that started at 8V without using a comparator?

May you indicate-me a good book where I can learn something about this issue?
I mean how to control the voltage of the panel with electronic devices.

I know the principle of operation of various electronic components. But I can not bring all this information to make an electronic circuit.



That is, I know the theory but then fail in practice. I understand that the components are in the diagrams but do not know anything about integrated circuits.

Can you help me in this task indicating books or websites where I can learn.
