Stepper motors have many more poles than servo motors. One rotation of a stepper motor requires many more current exchanges through the windings than a servo motor. The stepper motor's design results in torque degradation at higher speeds when compared to a servo.

Servo motors have many advantage. They can generate high servo motor torque over a wide speed range. Аnd are available in wider torque ranges and higher voltages. Servo motors dont suffer from resonance or vibration issues. They respond to disturbances with a torque much greater than their continuous capability and use … Read more
