Remove the Motor
Follow these steps to remove a motor from a machine.
Align the Rotor
Follow these steps to align the rotor prior to dismounting the motor.
1. Remove the black cap screw from hole B.
Refer to the motor outline on page 19 for the location of the compression
coupling fitting and alignment pin.
2. Use a flashlight to illuminate hole B.
3. Rotate the shaft by hand until the opening for the alignment pin comes into
view in hole B.
4. Remove the alignment pin from hole A, and install it in hole B.
5. Use a 8 mm hex bit to tighten the alignment pin in hole B to 18.0 N•m
(13 lb•ft).
Outer surfaces of a motor can reach high temperatures, 125 °C (275 °F), during operation.
Take precautions to prevent accidental contact with hot surfaces. Consider motor surface
temperature when selecting connections and cables to install on a motor.
Failure to observe safety precautions could result in personal injury or damage to
equipment.
ATTENTION
Servo drive power must be turned off before connecting or disconnecting the cables to the
motor, and if a cable is left disconnected at the motor end.
Arcing or unexpected motion could occur if the feedback, power, or brake cables are
connected or disconnected while power is applied to the servo drive.
Failure to observe these safety procedures could result in personal injury or damage to the
motor and equipment.
IMPORTANT
The alignment pin must fully engage the rotor. The shoulder of the alignment pin engages
the rotor when the pin is fully inserted.
