I've been learning and trying to reverse-engineer the logic, nature and anatomy of a stepper motor.
These motors come with certain specs as far as Vmax, A/phase and so forth. I have learned that a 1.8degree motor is 360/1.8 = 200 steps in the motor.
when trying to calculate desired RPM you use PPS (Pulse Per Second). in this case if we choose a desired 500RPM for the motor to output... the math would show:
(500Rpm / 60sec-min) = 8.33Rps.
Then
(200steps-in-motor-per-rev X (8.33Rps)) = 1,666 PPS.
My question is: If I want 500Rpm out of this motor....and I need 1,666 pulses per second to achieve 500Rpm, how is PPS a function of Voltage, Amperage and resistance? What would be the draw of the motor in and V and A at 500Rpm and 1,666PPS?
