Step 4: Selection of suitable actuators based on the maximum permissible speed
The maximum permissible speed depends on the order stroke and can be taken from the diagrams on page 11 of the data.
The spindle 20x5 mm is omitted.
Step 5: Selection of suitable actuators based on estimated service life
The mean force acting on the actuator is used to calculate the service life. The mean force Fm can be calculated using the formula on page 8.
With an average force of 795 N, a service life of > 1,700 km can be expected.
Step 6: Selection of the appropriate order stroke (working stroke + stroke reserve)
To prevent damage to the actuator, a stroke reserve of at least 20 mm is recommended at each end side:
Order stroke = working stroke + 2 x 20 mm
= 850 mm + 40 mm
= 890 mm
Step 7: Check all remaining parameters
e) temperature requirement of T
max
=35 °C is met
h) there are no specific requirements for the material
Result:
E/809050/10M/890 is the chosen electromechanical actuator, because it meets all requirements.
