(2019-9261a) © 2020 IMI International S.R.O. en 1.6.400.07 3.2 Selection of a motor For each actuator, two motor sizes are available. The selection of the motor is based on the driving torque T and rotational speed rpm which have to be calculated for each step of the load cycle. All values calculated must be below the intermittent torque the motor can deliver (diagr. pages 18 ... 21). T Torque Nm n Rotational speed min -1 v max,step Maximum velocity of each step m/s To avoid overheating of the motor, the mean torque T rms of the load cycle must be lower than the continuous torque (diagr. pages 18 ... 21). 4. Estimation of expected life time The estimated life time of the ball screw drive can be calculated according to DIN ISO 3408-5. Therefore, the mean velocity v m and the mean force F m must be calculated. Then, the life time in revolutions is calculated from the dynamic force C of the ball screw nut and the mean force. The life time L km in km is then calculated with the spindle pitch P. 5. Additional moutings To avoid bending of the actuator, the installation of additional mountings may be necessary. For each actuator size, the maximum unsupported length can be estimated with the forces in y- and z-di- rection using the diagrams on page 12. 5. Safety stroke Disregarding the initial set up, the actuator must not touch its me- chanical end stops. A safety stroke should be considered, respecting the applica tion boundaries and environments. We generally recommend a safety stroke of 20 mm per side for electric rodless actuators. The order stroke = working stroke + safety stroke of 2 x 20 mm. Please note, that during the initial set up, the actuator might exceed its nominal end position as given (over run "Dimension "X") in the drawing below.
