Hello Coleman;

Hi ejvargas,

Welcome to the RobotShop Forum. There are now several models of VEX continuous rotation motors, and you are talking about is the 3-wire version we have on the RobotShop website. The specifications are:

Stall Torque: 6.5 in-lbs
Free Speed: 100 rpm @ 7.5 volts
Voltage: 4.4 - 9.1 Volts (Motor life will be reduced operating outside this range)
PWM Input: 1ms - 2ms will give full reverse to full forward, 1.5ms is neutral
Dead Band: 1.47ms - 1.55m
Black Wire: Ground
Orange Wire: Power
White Wire: PWM signal

To get an idea of the maximum continuous torque, divide the stall torque by a factor of about 4 to 5.

The two new VEX motors are

2-wire 269:

All motor specifications are at 7.2 volts.
Actual motor specifications are within 20% of the values above.

2-wire 393:

Free Speed: 100 rpm (As Shipped)/160 rpm (High Speed Option)
