Removing and Replacing Multi-axis Stage Components Chapter 8
Replace the Rotary Motor
Follow these directions to replace a secondary stage rotary motor.
1. Disconnect the motor cables.
2. Remove the four M5 SHCS and lock washers that secure the motor to the
linear stage.
3. Remove the motor.
4. Mark the measured coupling position on the new motor shaft.
5. Loosen the M4 SHCS in the coupling and remove the coupling from old
motor shaft.
6. Position the coupling on the new motor shaft, align it with the mark made
in
step 4 , and then tighten the coupling.
7. Align the coupling halves and install the motor.
8. Secure the motor with four M5 SHCS and lock washers.
9. Torque each cap screw to 4 N•m (35 lb•in) using a diagonal tightening
sequence.
IMPORTANT Measure the position of the coupling on the motor shaft as
shown in panel B of the diagram above.
