Hi I'm new to this forum and currently a first year engineering student. I'm trying to build a motor control circuit so I can minimize the power draw. And I feel I need a bit of direction. I started with a 6v battery source a 6v motor: http://www.jaycar.com.au/productView.asp?ID=MD7000&CATID=9&form=CAT&SUBCATID=726 [Broken] and a DPDT switch. but this was too much power under load since I was aiming to get the motor under 1 watt so I looked around and read about PWM (Pulse-width modulation) and that it is commonly used to control motors and that it is possible to make a simple PWM control with a 555 timer. I tried following this http://www.dprg.org/tutorials/2005-11a/index.html [Broken] but it didn't seem to output enough voltage although I substituted an led in place of the motor and it worked alright I believe the voltage was too low. So I'm looking for a bit of direction on pwm and motor control in general there are a few other pwm circuits which I have looked at although I'm not sure what is best: http://www.electronics-lab.com/projects/motor_light/005/index.html http://www.electronics-circuit.com/advanced_DC_Motor_Control.html http://www.discovercircuits.com/DJ-Circuits/simplepwm2.htm Maybe some pointers on 555 timers may help as well. also I know some basic circuit analysis for dc and ac and I was wondering if anyone can point me in the right direction of how I would be able to analyse a motor in a circuit?
