Electrical Data
1.1 Definitions
100 K, 60 K values
100 K or 60 K is the average winding temperature rise in Kelvin.
105 K corresponds to a utilization according to temperature Class F.
60 K lies in the utilization within temperature Class B. The 60 K utilization is used:
• if the temperature of the enclosure/housing must lie below 90 °C for safety reasons
• or the shaft temperature rise would have a negative impact on the mounted machine
Generally, for all data, a permissible ambient temperature of 40 °C applies for naturally-
ventilated and force-ventilated motors; for water-cooled motors, a cooling-medium
temperature of 35 °C.
Torque characteristics
Several armature circuit versions (different rated speeds n
A high overload capability is provided over the complete speed control range.
The following limits always apply for all synchronous motor - drive converter module
combinations.
