Mount the Motor
Follow these steps to mount the motor.
1. Provide sufficient clearance, heatsink mass, and air flow for the motor so it stays within
the operating temperature range of 0…40 °C (32…104 °F).
Do not enclose the motor unless cooling air is forced across the motor, and keep other
heat producing devices away from the motor. Heatsink requirements are listed in a
footnote to the
Specifications on page 20 table.
2. Verify the axial and radial shaft loads of your application do not exceed those listed in the
Motor Load Force Ratings on page 15.
3. Position the motor with the cable connections beneath the motor.
Refer to the To Prolong Motor Life on page 4 section for a visual reference of correct
motor and cable positioning.
4. Properly mount and align the motor:
•
Bulletin MPL motors include a mounting pilot for aligning the motor on a machine.
•
The index pulse occurs on a 2000 line encoder when the shaft key is aligned with the
connectors.
•
Make sure belt loading is within the motor limits, and all belts and pulleys are
properly aligned.
•
Follow manufacturer recommendations for gearboxes, pulleys, or other motor
accessories.
ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact to the shaft is
applied during installation of couplings and pulleys.
Do not strike the shaft, couplings, or pulleys with tools during installation or removal.
ATTENTION: Outer surfaces of the motor can reach high temperatures of 125 °C (275 °F) during
operation.
Take precautions to prevent accidental contact with hot surfaces. Consider motor surface
temperature when selecting motor mating connections and cables.
