Thermal limiting torque when the motor is at a standstill, corresponding to the
utilization according to 100 K or 60 K . This torque is available at n = 0 for an
unlimited time. M
0
is always greater than the rated torque M
rated
.
Motor phase current, in order to generate the particular stall torque.
1FT6 and 1FK6 motors are supplied with sinusoidal currents; 1FT5 motors with
squarewave currents. For 1FT5 motors, the current I
0
corresponds to the peak
value.
Thermally permissible continuous torque at the motor rated speed.
RMS motor phase current, in order to generate the particular rated torque.
Power, which is still available at rated speed and rated torque.
Max. torque, which is still available at rated speed for acceleration.
Motor phase current, in order to generate the limiting torque.
This current limit is determined by the magnetic circuit. The magnetic material
will be reversibly de–magnetized if it is exceeded, even for a short time.
The maximum permissible operating speed is n
max
. It is either defined by the
electrical (voltage limiting characteristic) or mechanical (centrifugal forces, bear-
ing stressing). The lower value is always specified in the list data.
