Why can't the stepper motor run at high speed? Even if the servo motor speed reaches 3000 rpm, the torque is still very large, but if the stepper motor speed reaches 500 rpm, the torque will be very small. Why does this happen? The working principle of the stepper motor is to generate a magnetic field by energizing the internal battery coil in sequence, and then attract a rotor in the middle. However, if it rotates at a high speed, its power-on time will be very short. If the speed is too fast, the current will be greatly reduced, and the magnetism will naturally decrease. If the magnetism decreases, the torque will decrease. Why can the servo motor maintain very strong torque at high speed? Do you know why?
