Solar panel and motor: Any way to regulate the power transmission?
I'm an engineering student and for an individual hobby-like project i purchased a small solar panel and a small solar motor. I am planning on making a small solar powered toy car. The question i have is: is there a way to connect a control or some other ways of regulating the power that is absorbed by the cells? Other wise the motor will just continue to run. Any answer would be greatly appreciated. Thanks!
I assume it is a DC motor. You should have DC voltage coming out of the solar cell (For example 10V). You could use a transistor to switch the voltage on and off, then filter the output with an RC filter. You will have to choose the right RC time constant . It will have to be slower than the control pulse frequency, but faster than the desired motor response time.
If you switched the voltage with a 50% duty cycle, then filtered the output, you would get 5V, with a 75% duty cycle, you would get 7.5V, etc. Therefore, you could control the motor by controlling the duty cycle of the switching. A microcontroller like the BASIC Stamp can produce the control pulses.
