• Selection procedure(1) Calculate torque Ta applied to the coupling based on themotor output P and coupling operating rotation speed n.Ta [N·m] = 9550 ×Td = Ta × K (see below)P [kW]n [min −1 ](2) Calculate corrected torque Td applied to the coupling afterdeciding the service factor K based on load conditions.Load characterConstant Fluctuations: Slight Fluctuations: Medium Fluctuations: LargeIn servo motor drive, multiply the service factor K=1.2 to 1.5by the maximum torque of servo motor Ts.Td = Ts × (1.2 to 1.5)(3) Select a coupling size with permissible torque Tn thatbecomes equal or greater than the corrected torque Td.Tn ≥ Td(4) Depending on the bore diameters, the coupling permissibletorque may be limited. Refer to the “Specification” and“Standard bore diameter”.(5) Confirm if the required shaft diameter does not exceed themaximum bore diameter of the selected size.For machines whose load torques periodically fluctuatedrastically, contact us.SERVO FLEXSFC1.0 1.25 1.75 2.25• Simplified selectionThe table indicates suitable sizes based on the rated output, rated torque and maximum torque of general-purpose servo motors.
