AKM Operating Temperature
The standard operating temperature of an AKM is based upon the most temperature sensitive device. This is typically the bearings . The standard bearings that are used on the AKM put the operating temperature at -20 to +120 deg. C. We realize that some applications require different temperature and we in turn offer custom AKM's with different bearings. For example one of the options available is to get bearings with Aeroshell 22 grease. This provides a lower operating temperature of -40 to +120 deg C. When using the lower temperature bearings the customer would at that point need to make sure that the feedback device can withstand the lower temperature. Typically a resolver (capable of -55 to +155 deg C) would be used at lower temperatures and some encoders can go as low as -40 deg C.
