Im working on a home project where Im trying to build a circuit where the motor (24v 10A max at 3,000rpm) is controlled by a 555 timer (PWM). I ran the motor as a test using a wall power supply (24v 550mA). It ran well for a while until it burned the power supply out. Live and learn I suppose. I suspect I was getting some bad feedback, rather reversed voltage, from the motor and shouldve used a diode to protect the power supply. But Im not exactly sure. Im very uneasy with working with such high voltages especially at my experience level. What Id like to do is run the motor off say 12 or so volts but raise the amps. Ive read that, in simple terms, voltage is more closely related to the speed at which the motor will turn, while amps are related to the torque. How could I raise the amps without going crazy with the voltage? I would imagine somehow charging capacitors in parallel from a single source. Then pulsing the caps output to the motor
Could someone point me in the right direction?
Thanks in advance!
P.S. Ive drawn a schematic of a simple pwm circuit that Ive actually tested, it used 9v DC fed to the 555 which controlled an LED and small motor. But the schematic isnt very different from anything you may have seen online. I can still post if someone wants me to
PPS: I'm not on here expecting to just "get all the answers". I've never been opposed to doing my own homework. I certainly appreciate any help, though, and am only posting here because my own research isn't getting me very far. Again...thanks.
