Re: Treadmill motors as Servos

Les Newell, John, and Rich

I've been trying to learn how to select a dc motor, run it, and
control its speed for some time now. The more I search and read the
more confused I become. Your discussion on this subject has been
interesting to me. I was hoping that you could tell me, for the
Surplus Center ARGORD CORP permanent magnet motor (item # 10-1783)
the following.

What do I purchase from Surplus Center to convert 110 volts AC home
service to the dc voltage and current that this motor needs?

Then what do I purchase from Surplus Center to vary the speed of the
motor over its capable speed range?

I just want to purchase the motor, converter, and controller to put
together the system just to gain the confidence that I can actually
do it.

Also how do I wire the converter, and controller to the motor?

I see that the Surplus Center spec states that the motor is
reverseable, but the pictures that were posted showing the motor
label shows that the motor (model PA140B) is CW rotation. The label
says external fan, does that mean that a fan must be mounted somehow
to cool the motor?

Which Surplus Center fan is meant for the motor?

Thanks for your help, and God bless you all.
