I
0_S(eff)
Standstill continuous torque surface
I
0_L(eff)
Continuous current at standstill, liquid
M
max
The maximum torque that can be output for approx. 400 ms at
a maximum current of I
max
(guaranteed value which, owing to
production tolerances, may be up to 20% higher). The achiev-
able maximum torque depends on the drive controller used.
Only the specified maximum torque in the selection lists is
binding.
I
max(eff)
Maximum short-term branch current (root-mean-square value)
of the motor permitted without damaging the permanent mag-
netic circuit of the motor.
K
M_N
Ratio of the torque to the motor phase current (root-mean-
square value) at a motor temperature of 20°C. Unit Nm/A. Valid
up to approx. i = 2x I
0_60(eff)
.
K
EMK_1000
Root-mean-square value of the induced motor voltage at a
motor temperature of 20°C and 1000 revolutions per minute.
Unit: V/1000min
-1
.
R
12
Resistance measured between two winding ends in ohms (Ω).
L
12
Inductivity measured between two winding ends in mH.
C
ab
Capacity of short-circuited power connections U, V, W against
the motor housing.
p Number of pole pairs of the motor.
J
rot
Moment of inertia of the rotor without the optional holding
brake.
n
max
Maximum permissible speed of the motor. Limiting factors can
have mechanical (centrifugal forces, bearing stress) or electri-
cal (DC link voltage) causes.
m Motor mass without the holding brake option, given in kg.
L
P
Airborne noise emitted, in dB(A).
