4.1.5 Example of a Characteristic Curve
S1 (60K) Continuous operation curve of the motor (according to EN 60034-1;
1998), natural convection
S1 (100K) Continuous operation curve of the motor (according to EN 60034-1;
1998), natural convection
S1 (surface) Continuous operation curve S1 of the motor (according to EN 60034-1;
1998), surface cooling.
S3 (25% ED) Intermittent service characteristic curve at 25% operating rate of the
motor (according to EN 60034-1; 1998) and max. cycle time of 10 min.
① - ④ Characteristic voltage limit curves When a speed at the safe commuta-
tion limit is reached, the voltage limit curve limits the available maximum
torque Mmax. The maximum motor speed is determined by the DC link
voltage used. There are separate characteristic curves for the various
drive controllers in connection with the power supply unit and the supply
voltage used.
① Mmax for IndraDrive, controlled feed, 3 x AC 400V
② Mmax for IndraDrive, uncontrolled feed, 3 x AC 480V
③ Mmax for IndraDrive, uncontrolled feed, 3 x AC 440V
④ Mmax for IndraDrive, uncontrolled feed, 3 x AC 400V
