(Open loop) 7 differences between stepper motor and servo motor: control accuracy – servo motor control accuracy can be set according to the encoder, and the accuracy is higher; low frequency characteristics – stepper motor is easy to vibrate at low frequency, but servo motor does not; torque frequency Features – The torque of the stepper motor decreases as the speed increases, so its maximum working speed is generally <1000r/min, and the servo motor can output the rated torque within the rated speed (generally 3000r/min), and it is constant above the rated speed. Power output, the maximum speed can reach 5000 r/min; overload capacity – the stepping motor cannot be overloaded, and the maximum torque of the servo motor can be overloaded 3 times; running performance – the stepping motor is controlled by open loop, and the F speed of the servo motor is controlled by closed loop Response——The starting time of the stepper motor is 0.15~0.5s, the servo motor is 0.05~0.1, and the fastest can reach the rated 3000r/min in 0.01s.
