I have a quick question about the torque speed curve charts from Keling at http://www.kelinginc.net/KL23H286-20-8BT.pdf (for example)
My question, what does pps stand for? (It's the unit along the X axis) I might assume that pps is pulses per second or something similar. How do I convert that into rpm.
I might guess that because it's a 200 step per revolution motor, I can just divide by 200 and then multiply by 60. To confuse me more, the chart says they are running the motors in half steps. Does this mean there are 400 steps per revolution?
One more thing. I understand that to half step a person alternates between energizing one coil, and energizing both coils. Does this mean that if I take full steps and energize only one coil at a time, I'll have less torque than the chart? If I take full steps and only energize both coils, I'll have more torque than the chart?
Thanks very much.
