The minimum operating temperature Compumotor Servo motors is as follows
|Motor Size||Feedback||Min Temp|
|All SM, BE, N, J, M||Resolver||-30°C|
|All SM, BE, N, J, M||Encoder||0°C|
|All Integrated Gearheads||Resolver||-25°C|
|All MPP Rotary||Encoder or Resolver||0°C|
|All MPM Rotary||Encoder or Resolver||0°C|
|All APEX and Z||Resolver||-20°C|
|Custom motors can be ordered that will run at lower temperatures|
The limitiation on the resolver motors is not due to the resolver, but the grease in the bearings. If lower temperatures are needed, a custom motor with lower temperature bearings should be requested. For condensing environments, a protective winding coating or vented motor are available as a custom.
Likewise the limitation on the integrated gearheads is the grease in the bearings.
Minimum/Maximum Storage temperatures:
Minimum is -50c non-condensing.
Maximum is 120c for an encoder feedback.
Maximum is 150c for a resolver feedback.
