This introduction provides a comprehensive overview of the MKD090B-047-GG0-KN motor, highlighting its key features, application scenarios, and technical parameters.

Please note that they all provide a stop accuracy of approximately +/-0.02°, which is below the typical 3 arcseconds or +/-0.05°

repeat stop accuracy specification of a stepper motor. While a stepper motor provides better repeatability at 7.2° steps or near

perfect repeatability at 360° steps, the stop accuracy of a servo motor is dependent on its encoder resolution.

The stop accuracy of a stepper motor is highly dependent upon its winding characteristics, the precision of its rotor construction,

and the number of teeth/poles in the rotor. The stop accuracy of a servo motor is dependent upon the assembly precision, the encoder

resolution, and the control algorithm. To some extent, you could say that a stepper motor is “mechanically designed” for positioning applications, while a servo motor is “electrically designed” for positioning applications.
