Preparing the Motor for Installation
Follow these steps to prepare a motor for installation.
1. Verify 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 table.
2. Wipe the shaft and the rotor hub to remove excess grease or other
contaminants.
A light oil coating is acceptable.
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.
