Re: How do you figure IPM?

Hi,
You have 120rpm and it take 20 turns to go one inch. Thus
20 into 120 gives you a speedy 6" per minute. You need to increase
your voltage to the motor while limiting the current. I use a 12v
computer supply and 8ohm 20watt resistors with my 5V motor. I get
12" per minute.
