All ClearPath-SC motors have unthreaded mounting bosses on the rear
casting to accommodate standard DC computer fans (60mm for NEMA 34
motors, or 40mm for NEMA23 size motors). See the diagram below for
mounting dimensions, hardware and fan sizes. Teknic does not sell
accessory fans, but they are readily available through electronics suppliers
including Digikey and Mouser.
Note: As a self-protective measure, ClearPath-SC motors will shut down
when the rear enclosure reaches 80
°
C (176
°
F). After a thermal shutdown
occurs, the motor must cool sufficiently before it will operate again.
Reminder: If you install a fan, you'll have to power it. Most computer
fans require 12VDC or 24VDC.
