Re: OOPS! Need bigger steppers

Hi Gary, truth be told the fact is you should be looking for motors
with the lowest voltage you can find. Simply put these motors will
have the lowest inductance which means you will get the highest
speed. Also look at the oz-in rating of the motor more torque means
more turning power.

The combination of lowest motor voltage and highest power supply
voltage will give you the maximun speed. Your motor will not burn
out because the drive is a chopper drive and it never lets the
current go above 2 amps.
