Abbrev. Unit Definition
7.1 General Technical Data
I 0M [A] standstill current of the motor
effective value of the motor current at standstill torque
M 0
I NM [A] rated motor current
effective value of the motor current at rated torque M N
I SM [A] peak motor current
effective value of the motor current at peak torque M SM
I NC [A] rated current of MotorController
rated controller current (permanent operation S1)
I SC [A] peak current of the MotorController
peak current of the controller for acceleration phases
also effective value of the motor current at peak torque
M SA supplied for a short time by the drive combination
J M [kgcm 2 ] rotor moment of inertia
the rotor moment of inertia refers to a motor with
resolver and without brake
J ges [kgcm 2 ] moment of inertia
total moment of inertia (motor and load)
K M [Nm/A] torque constant of the motor
ratio of standstill torque M 0 and standstill current I 0M
(e.g. K M20 for 20°C).
m [kg] mass
motor mass without brake and without fan
M 0 [Nm] standstill torque of the motor
permanent torque (100% ED) at speed n 0 . With an
ambient temperature of 40 °C, an overtemperature of
60 °C occurs on the motor casing, depending on the
thermal motor time constant
M N [Nm] rated motor torque
permanent torque (100% ED) at rated speed n N . Due
to the speed-related losses, it is less than M 0 . With an
ambient temperature of 40 °C, an overtemperature of
60 °C occurs on the motor casing, depending on the
thermal motor time constant
M S3 [Nm] torque for intermittent operation S3 = 25% ED
