Servo motors and stepper motors are widely used, and there are many purchasers who cannot figure out the difference between the two, so I am not sure what type of motor to choose, which may lead to the wrong choice when buying. Today, Xiaobian will share with you the difference between servo motors and stepper motors to facilitate your purchase.

The difference between servo motor and stepper motor

(1) Different overload capacity

The overload capacity of the AC servo motor is relatively strong, and the stepper motor is weak in this respect.

(2) Different speed response performance

The acceleration performance of the AC servo system is relatively good, and the acceleration response time of the stepping motor is relatively long.

(3) The control methods are different

The servo motor controls the rotation angle by controlling the length of the pulse time, and the stepper motor controls the rotation angle by controlling the number of pulses, and one pulse corresponds to one step angle.

(4) Different moment-frequency characteristics

AC servo motor belongs to constant torque output, that is, it can output rated torque within its rated speed, and constant power output above the rated speed.

The torque frequency output by the stepper motor will gradually decrease as the speed increases.
