I see you already found out how to measure current with a meter. Some meters require you to plug the red lead into a different socket labelled specifically for measuring current. Don't worry though, they are lebelled with a big A right beside the socket for the red probe lead.Ill grab a multimeter tomorrow, how does one go about measuring? It will probably be easier than asking Roy, but ive messaged him, so the ball is in his court..
Ive been describing 2 different styles of machines in previous posts.. coil and the rotary, its the rotary that has the motor im looking to build my powerpack for..
I use about 4.5v for my rotary machine to do dotwork.
Rotary is just a small DC motor, it should have a consistent DC current draw, but will draw a little extra when it is working harder, or starting up.
If you end up measuring yourself due to a delay or Roy's message, can you get a couple readings?
Set the power supply at the 4.5V you want, and record the current draw.
Set the power supply to another voltage or two that you work with and record those current draws as well.
I'm not asking you to burn out your motor so only give us the higher end of the reading your after. If we get 2 or 3 sets of Voltage to Current readings, we can be sure to recommend an ideal, cost effective, easy solution for you.
