Re: Stepper Motor Question - Easy for the PROS to answer

Shawn,

You are correct. The reason for showing both is because a classic
half-step drive sequence alternates between both windings "on" and
one winding "on". The "one" winding on torque reflects what you can
expect with the motor stopped on its "weak" half-step.
