14. SERVO MOTOR
(2) For the servo motor shaft with a keyway, use the screw hole in the shaft end. For the shaft without a
keyway, use a friction coupling or the like.
(3) When removing the pulley, use a pulley remover to protect the shaft from hard load and or impact.
(4) To ensure safety, fit a protective cover or the like on the rotary area, such as the pulley, mounted to the
shaft.
(5) When a threaded shaft end part is needed to mount a pulley on the shaft, please contact us.
(6) The orientation of the encoder on the servo motor cannot be changed.
(7) For installation of the servo motor, use spring washers, etc. and fully tighten the bolts so that they do not
become loose due to vibration.
14.3.3 Permissible load for the shaft
POINT
Do not use a rigid coupling as it may apply excessive bending load to the shaft,
leading to shaft breakage.
For the permissible shaft load specific to the servo motor, refer to the chapter of the servo motor series.
(1) Use a flexible coupling and make sure that the misalignment of the shaft is less than the permissible radial
load.
(2) When using a pulley, sprocket or timing belt, select a diameter that will fit into the permissible radial load.
(3) Excess of the permissible load can cause the bearing life to reduce and the shaft to break.
(4) The load indicated in this section is static load in a single direction and does not include eccentric load.
Make eccentric load as small as possible. Not doing so can cause the servo motor to be damaged.
14.3.4 Protection from oil and water
Avoid foreign matter, such as oil, from being inside the axis on the servo motor. When installing the servo
motor, consider the items in this section.
