Abstract
The temperature of motor surfaces is still a major concern of those operating equipment in hazardous (classified) areas. This surface temperature must be below the ignition temperature of the atmosphere under all possible operating conditions for Division 1 environments. Currently a 2150C maximum surface temperature is a must for a motor that can be operated in any Class I, Group D, Division 1 area without qualification. These lower temperatures are also causing a renewed interest in motor performance in Division 2 areas.
