Abstract:

The servo motor is a kind of high precision motor, for its own assembly tolerance is high (such as the coaxial/perpendicularity/beating degree etc.). From the servo motor shape position tolerance factors considered by dimension chain closed-loop, extremum method and least square method were used two methods to calculate degree of rabbet coaxial to the front cover of the servo motor, and compared according to the results, a reasonable description of each method.

Key words: servo motor, form and position tolerance, dimension chain closed loop, extreme value method, least square method
