Enter points P2 and P4 and connect. This line is the new drive converter output
voltage V
mot, new
.
Rated speed n
N
The characteristic speed range for the motor is defined in the speed-torque diagram using
the rated speed.
Stall torque M
0
Thermal limit torque at motor standstill corresponding to a utilization according to 100 K or
60 K. This can be output for an unlimited time at n = 0. M
0
is always greater than the rated
torque M
N
.
Stall current I
0
Motor phase current to generate the particular stall torque.
For 1FT6 and 1FK☐ motors, sinusoidal rms currents are specified.
Rated torque M
N
Thermally permissible continuous torque for S1 duty at the rated motor speed.
Rated current I
N
rms motor phase current in order to generate the particular rated torque.
Max. current I
max, rms
This current limit is only determined by the magnetic circuit. Even if this is briefly exceeded, it
can result in an irreversible de-magnetization of the magnetic material.
