Rated torque M
N
Thermally permissible continuous torque in S1 duty at the rated motor speed.
Rated speed n
N
The characteristic speed range for the motor is defined in the speed-torque diagram by the
rated speed.
Rated current I
N
RMS motor phase current for generating the particular rated torque. Specification of the RMS
value of a sinusoidal current.
Braking torque M
br eff
M
br eff
corresponds to the average braking torque for armature short-circuit braking that is
achieved through the upstream braking resistor R
opt
.
DE
Drive end = Drive end of the motor
Maximum speed n
max
The maximum mechanically permissible operating speed n
max
is the lesser of the maximum
mechanically permissible speed and the maximum permissible speed at the converter.
NDE
Non-drive end = Non-drive end of the motor
Static torque M
0
Thermal torque limit when the motor is at a standstill corresponding to the motor thermal
class. M
0
is always ≥ the rated torque M
N
.
Stall current I
0
Motor phase current to generate the particular static torque (M
0
= k
T
• I
0
). Specification of the
RMS value of a sinusoidal current.
