tions in the mounting structure that can cause fatigue in structural members. A mechanical engineer should check the machine design to ensure that the mounting structure is adequate.

WARNING

Improper motor mounting can jeopardize personal safety, and

compromise system performance.

For Compumotor motor dimensions, see Select a Motor earlier in this chapter.

MOTOR TEMPERATURE & COOLING

The motor’s face flange is used not only for mounting; it is also a heatsink. Mount the face flange to a large thermal mass, such as a thick steel or aluminum plate, which should be unpainted, clean, and flat. Heat will be conducted from inside the motor, through the face flange, and dissipated in the thermal mass. This is the best way to cool the motor. You can also use a fan to blow air across the motor for increased cooling, if conduction through the flange does not provide enough cooling.

MOTOR MODIFICATIONS

Modifying or machining the motor shaft will void the motor warranty. Contact a Compumotor Applications Engineer (800-358-9070) about shaft modifications as a custom product.

EXTENDING MOTOR CABLES

If you need to extend Compumotor motor cables beyond the standard

10 feet (3 m), consult the table below for recommended wire sizes. Cables longer than 50 feet (15 m) may degrade system performance. Do not extend cables beyond 200 feet (61 m).
