Motor mass
m = motor mass in standard design, without holding brake, specified in kilo‐
gram [kg].
Sound pressure level
L
P
= at a distance of 1 m, with PWM = 4 kHz. Unit: [dB(A)].
Thermal time constant
T
th
= duration of the temperature rise to 63% of the final temperature of the
KTY in the coil end under load at rated torque in S1 operation mode and sur‐
face ventilation by direct-connected fan units.

Cycle duration
T
C
= duration of the cycle in S6 operation mode, required to reach the ther‐
mal steady-state condition where the maximum temperature value corre‐
sponds to the final temperature in S1 mode (see
according to EN 60034-1" on page 17
).
Number of pole pairs
p = number of pole pairs of the motor.
Allowed coolant supply tempera‐
ture

chapter 9.8.6 "Coolant inlet temperature " on page 203
Constant for determining the pres‐
sure drop with water as cooling
medium
Δp
diff
= pressure drop in bar without quick coupling at Q
min
.
If the coolant port is provided with a quick coupling (optional), the following
constant of the quick coupling has to be taken into account in addition to the
pressure drop constant specified in the data sheet:
k
dp2
Pressure drop constant of the quick coupling
l/min
Coolant flow rate
Fig. 4-4:
Constant for determining the pressure drop with quick coupling
When the quick coupling (optional) is used, this results in the following pres‐
sure drop across the complete motor:
Δp
diff2
Pressure drop with quick coupling
k
dp
Constant without quick coupling (see motor data sheet)
k

Constant with quick coupling
Q

Pressure drop with quick coupling
When other couplings or coolant ports are used, the correspond‐
ing pressure drop value has to be taken into account by the cus‐
tomer while designing the coolant system.
