Hi guys,
Does anyone know how to calculate Power Rating and RPM from the specification of Stepper?
I was told that formula:
Power (KW) = (Torque in N-m) x RPM/ 9.55
What I got is NEma 34, holding Torque 3N-m, Current 2A
Assume i use 35Vdc supply, then P = IxV = 70Watt (That's tooooo small??)
Then RPM = Power (KW) x 9.55 / Torque = 0.2 RPM????
That's again seem strange??
Best way might be to look at performanace curve, but any idea to get general number?
Thanks in advance.
