5.4 Speed-torque characteristic
5.5 Motor selection
Basic recommen-
dations • Only use motors with at least thermal classification F.
• Use TF thermistor sensors.
• Preferably use 4-pole motors. This applies particularly if you are operating geared
motors with a high oil filling level as a result of their vertical mounting position. The
churning losses are very great with 2-pole motors.
• For operating conditions other than S1 operation: Operate the motor at its listed pow-
er without forced cooling.
