How is the power of a stepper motor calculated? Which parameters need to be known? Why is power generally not indicated on motor nameplates?
Stepper motors are generally used for speed control over a wide range, and their power varies; they are usually measured in terms of torque. The conversion between torque and power is as follows: P = Ω·M, where Ω = 2π·n/60, so P = 2πnM/60. Here, P represents power in watts, Ω represents the angular velocity per second in radians, n represents the rotational speed in revolutions per minute, and M represents torque in Newton-meters. For half-step operation, P = 2πfM/400, where f represents the number of pulses per second (abbreviated as PPS)
