Stepper motor selection is not based on power to select, but according to the combination of speed and torque to select, although power = speed * torque, but the same power of the motor at high speed can drive a load, but not necessarily able to drive the same power of low-speed load, in addition, the same stepper motor, in different speeds or different driving voltage at different power power is not the same, but in order to give a general power concept, According to the above distance-frequency diagram, we calculate that the SST39D2010 Shinano 39 stepper motor is about 0.18Nm when driving 2000pps without subdivision, and the output power is about 11.3W.
