2
For nominal voltage and +40 °C ambient temperature and at modulating torque load.
3-phase asynchronous motor
type IM B9 according to IEC 60034-7, IC410 cooling procedure according to IEC 60034-6
Refer to motor name plate
Permissible variation of mains voltage: ±10 %
Permissible variation of mains frequency: ±5 %
Category III according to IEC 60364-4-443
Standard: F, tropicalized
Option: H, tropicalized
Standard: Thermoswitches (NC)
Option: PTC thermistors (according to DIN 44082)
PTC thermistors additionally require a suitable tripping device in the actuator controls.
Self-locking: Speeds up to 90 rpm (50 Hz) or 108 rpm (60 Hz) and from size SA 35.1 for output speeds
up to 22 rpm (50 Hz) or 26 (60 Hz)
NOT self-locking: SA 25.1 and SA 30.1 for output speeds from 125 rpm (50Hz) or 150 rpm (60Hz) and
from size SA 35.1 for output speeds from 32 rpm (50Hz) or 38 (60Hz).
Multi-turn actuators are self-locking, if the valve position cannot be changed from standstill while torque
acts upon the output drive.
