Do you choose the step motor or the servo motor?
The servo is closed-loop control, and the step is not closed loop, so the accuracy of servo wins. The bottom line is whether you are actually using the work, or the application of the class, or something else.
The step forward and the servo are not afraid to turn around frequently. The problem is speed, you need to be able to move fast and you're not going to be able to move, The other key can't eat to see how much bond and force you have. A 0.5 S90 degree step can also be done. You're looking at the torque. The step usually does not have the rotor stop wobble, the servo is if the parameter is not set up very well. Focus on your control
This is more suitable for servo motors. First, stepper motors have the largest start frequency, once above a start frequency can't start, that is to say, the stepper motor to achieve a certain speed need longer time to speed up the process. Relatively speaking, the characteristics of the stepper motor is high torque output is stable under the condition of low frequency, frequent positive &negative need motor has a very high response and high speed stability, this is not a step motor strengths, it is precisely the characteristics of the servo. In addition, the motor stator no direct contact, so there is no return gap problem, but frequent positive &negative, step step electricity opportunities have lost phenomenon. The server is given feedback by the encoder, so you can be completely satisfied with this issue.
