Reference Output Power for Stepper Motor

The output power (W) of a servo motor is indicated as "rated output power" when it is running at "rated speed."
On the other hand, as stepper motors, with their characteristic high precision positioning and high torque at medium and low speeds, they have no "rated speed."
Therefore, no "rated output power" is given.

The following is a list for your reference for how the torque values for standard type motors in each series of stepper motors (AC input) correspond to what W of servo motors' rated torque.
