• Motor Sizing Calculations

    Selection ProcedureTorqueSpeedThe first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation: 1. Dimensions and mass (or density) of load 2. Dimensions and mass (or density) of each part 3. Friction coefficient of the sliding surface of each moving part Next you will need to determine th
