In the process of communication with customers, customers often ask such a question: "what is the power of this stepping motor?". Today, the engineering and technical personnel of Beijing limaisheng Control Technology Co., Ltd. will discuss with you the "power" problem of the next step motor.

Users who contact the stepper motor for a long time will surely find that there is no power in the stepper motor specification, and usually select the type by referring to the torque at the corresponding speed. The reason why the power (W) is not marked in the specification of stepping motor is that there is no concept of "rated speed" for stepping motor. The power (W) of AC motor and servo motor usually refers to the power (W) when the motor operates at "rated speed", that is, "rated power". Stepping motor is generally used for speed regulation in a large range, and its power is variable. The power (W) calculated by substituting different rotating speeds will also be different. Generally, it is only measured by torque. The estimation formula of torque and power is as follows:

P=ω·Mω=2·π·n/60P=2·π·n·M/60=0.1047×n×M

Its p is the power in atts (W), ω is the angular velocity in radians per second (rad / s), n is the rotational speed per minute (R / min), and M is the moment in Newton meters (n · m). P = 2 π FM / 400 (half step operation), where f is the number of pulses per second (PPS for short).
