endobj etc etc? %PDF-1.6 %���� A root-mean-square (RMS) calculations used to determine an effective torque required by the motor to be compared with the continuous torque rating of the motor. ORIENTAL MOTOR's experienced team members know the technology inside and out. RPM. This translates to high requirements for torque and speed. As mentioned previously, acceleration torque is made up of inertia and acceleration rate. 0000002639 00000 n Sizing and selecting the servo motor requires determining both the continuous and intermittent drive torques required for the application. This component is a function of the inertia of the system and the acceleration rate. After years of developing servo motor sizing programs for Windows I deemed it necessary to document the motor sizing process beyond the regular help files. If the motor speed is varied, the acceleration torque or deceleration torque must always be set. (Refer to the below sections on calculations for each.). at the motor drive shaft of the mechanism. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque. This calculator determines the torque at every control position, from 1 degree to the maximum deflection specified. If you want the load to be up to speed within 50 milliseconds, it’s likely that a torque wrench will fly off. For servo motors, there is another calculation that must be done, which is RMS torque. How to calculate inertia of a drive system The load torque component is usually due to friction and/or gravity and is always acting on the motor. or 20cm from the axle?
