Space
Parker frameless motors have been specified into a series of lunar rovers, which will be making their way to the moon over the next several years.
The motors are being used to rotate the lunar tires that propel the vehicles across the moon’s surface. Some of the rovers will have redundant motors (2 per wheel). With both motors operating together, peak performance can be reached. If a failure occurs to one motor, the other motor can still operate in a sufficient manner to complete the mission.
The motors were sized to operate on 48vdc and at vacuum levels down to 10 ^-12 torr. Heat dissipation is always a concern in an environment with no atmosphere.
Parker made sure to provide in-depth information such as the Dissipated Power Speed Curve on page two.
With this information, the customer was able to identify proper conduction and radiation paths in the design of a special housing that helps to wick heat away from the motor.
By optimizing the performance of the motor in such a way, the overall envelope size and weight was kept to a minimum. This feature was important to the success of the design. Whether being used for rovers on the moon, for robots here on earth, or for equipment in the factory, Parker has the range of products, information, and support to satisfy your application needs.
