The step motor is approximately equal to the amount of watts
You also have to look at your speed, if 300rpm RPM, that's 31.4 W. If you say that the 1NM is the torque, it's not going to be that big a torque when it's actually running, it's not going to be that big. By the way, the selection parameters for stepping motors are not determined by power, but by torque and speed.
You should not have used a step motor, and even if you go to 1500rpm, the torque is almost empty, and there is probably a 1NM torque, not to mention 3000rpm RPM. The more common use of stepper motors is 90 ~ 900rpm, and the 300rpm I give you is a medium-speed range. There is no stepping motor that you are asking.
Your question is certainly not a problem. You use a current meter to measure the power in the circuit, and the speed is inversely proportional to the current. The higher the instruction of your driver controller, the smaller the current. Until the step motor is missing your instructions, there is a "missing step". Why is the rotational speed inversely proportional to the current at constant voltage? This is because the higher the speed, motor coil for cutting magnetic induction line on the induction electromotive force is higher, the electromotive force, contrary to you to provide the power supply voltage of direction, offset some of the voltage, the current becomes smaller. So the power goes down and the torque goes down. When the speed is very high, you stop it gently rotating shaft, the motor will stop to "shake", this is also the phenomenon of "step", causing it to turn. After you understand it, you can't calculate the power of the motor based on the information you provide. Input power = torque * speed (RPM) * 360 ° n/(PI * 60) When the speed is 100rpm, and the torque is 1N/M, the power is 190.99 watts.
You've seen which step motors are overpowered You don't have to do this for a step motor
Your CPU responds, but the step motor doesn't respond. The current technology for stepping into the motor, in practice, is not up to what you say about 1500-3000 cycles per second. The theoretical values are high, but a lot of them are based on the performance of the drive, and the reasonable combination can actually go so high, but the torque is almost zero. The actual application of stepping into the motor does not need to be so fast, and if needed, no stepping into the motor
