The difference between stepper motor and servo motor
1. Different control methods

Stepper motor: The rotation angle is controlled by controlling the number of pulses, and one pulse corresponds to one step angle.

Servo motor: control the rotation angle by controlling the length of the pulse time.

2. Different workflow

Stepper Motor: Workflow Generally, two pulses are required for stepper motor work: signal pulse and direction pulse.

Servo motor: Its workflow is a power connection switch, and then connect the servo motor.

3. Different low frequency characteristics

Stepper motor: low frequency vibration is prone to occur at low speed.

Servo motor: runs very smoothly and does not vibrate even at low speed.

4. Different moment-frequency characteristics

Stepper motor: The output torque decreases with the increase of the speed, and it will drop sharply at a higher speed, so the maximum working speed is generally 300 ~ 600r/min.

Servo motor: It is constant torque output, that is, within its rated speed (generally 2000 or 3000 r/min), it outputs rated torque, and above the rated speed, it is constant power output.

5. Different overload capacity

Stepper motors: generally do not have overload capacity.

Servo motor: has a strong overload capacity.
