1. actuators function in the same manner as a brushless servomotor The servo amplifier is used to rotate the motor at controlled speed and torque and for controlled numbers of revolutions and move times This rotary motion is translated into linear motion by the internal planetary roller screw mechanism of the EL Series linear actuator The relationship between the rotary motion of the motor and the linear motion of the actuator corresponds to the following relationships Linear Distance Traveled in Motor Revolutions Roller Screw Lead Linear Speed in sec Motor RPM 60 Roller Screw Lead Linear Force lbf Motor Torque in lbf 2z efficiency Roller Screw Lead in All of the above relationships require proper anti rotation of the EL Series actuator rod EL Series Explosion Proof Actuator Manual 6 14 2011 PN 23942 Exlar Corporation Rev D 952 500 6200 For more information on sizing and selection of EL Series actuators and servo amplifiers to power them consult the sizing and selection section of the Exlar catalog Motor RMS current must be maintained at a level below the continuous current rating of the EL Series actuator or damage to the motor stator will result The peak current setting must be maintained at a level below the peak current rating of the EL Series actuator or damage to the stator will result A Care should be taken not to exceed the physical travel limits of EL Series Actuators Doing so wi2. insure that the grease is well worked in Grease must reach the bearing just behind the bearing that is visible as well Use the following amounts of grease for each size roller screw and bearing EL30 0 75 in 4 3 Reassembly 1 Rethread the roller screw into the internally threaded cylinder ITC It is a multiple start screw and this is not always easy DO NOT FORCE THE ROLLER SCREW INTO THE CYLINDER It is best to have the actuator vertical with the open end of the roller screw cylinder facing up Position the roller screw above the cylinder so that it is aligned axially with the ITC Slowly turn the roller screw 1 4 to 1 2 a turn counterclockwise with it in contact with the ITC This will help to align the threads on the roller screw with the threads in the ITC Rotate the roller screw clockwise and it should begin to thread into the cylinder If it does not turn freely remove it and begin again When threading the screw into the cylinder it will roll freely into the actuator When it reaches the portion of the cylinder that contains the motor magnets the roller screw will be more difficult to turn because of the magnetic field of the magnets THIS IS NORMAL Continue to thread the roller screw into the cylinder When it reaches the bottom it will become difficult to turn and the motor and bearings will begin to rotate with it The roller screw is now fully inserted into the cylinder 2 Place a small amount of seal lubricant on the inside
