Can you ID this motor?

Posted by Vinnie on August 15, 2006, 12:42 am

I'm new to electronics and thought I was working with a DC motor. The
reason I thought it was DC was becuase it was powered by a single AA
battery. After reading the information at
http://www.robotics.com/motors.html , I'm thinking the motor I have is
actually a stepper motor. So, I bought the motor in question at a hobby
shop for 99 cents and looks similar to the motor pictured at this URL,

What type of motor do you think this is? Thanks for the help!

That motor looks like a regular DC motor. A stepper motor will have several
leads - your motor only has 2.

Also, if it turns continuously when hooked up to the AA battery, you know it is
not a stepper. A stepper motor needs
some kind of driver electronics to sequence the coils in a particular order. (
I'm sure others on here will correct me
if I am wrong ! )

Hope that helps !

bah, its not even one of the good ones with the encoder on it (the
digital servo motors)

and they didn't include the linear encoder :(

This particular motor is surplus out of an HP printer, and is worth more
or less 99 cents. People throw these old printers away because a new
printer is so cheap these days.

It is indeed a DC motor.
