Temperature Rise |
![](http://catalog.orientalmotor.com/plp/mm/spacer.gif) |
Temperature rise of the windings is 176°F (80°C) or less measured by the change resistance method. (at rated voltage, at standstill, 2 phases energized)(See requirements for UL/CSA)
|

Temperature Rise (UL or CSA) |
![](http://catalog.orientalmotor.com/plp/mm/spacer.gif) |
When using as a UL or CSA recognized component, make sure the temperature rise of the windings is 50°C or less by mounting the motor to an aluminum heat sink 7.87 x 7.87 in., 0.39 in. thick.
