● Primary section precision cooler data
● Secondary section cooling data
General conditions
U
DC
Converter DC link voltage (direct voltage value).
Comment
: U
a max
is the maximum permissible converter output voltage
T
VORL
Maximum flow temperature of the water cooling if the motor is to be utilized up to its rated force F
N
.
T
N
Rated temperature of the motor winding
Ratings (S1 duty)
F
N
Rated force of the motor
I
N
Rated current of the motor at rated force F
N
v
MAX, FN
Maximum velocity up to which the motor can deliver the rated force F
N
P
V,N
Motor power loss at the rated point (F

. Losses due to friction and
eddy currents are ignored.
Comment:
The power loss is calculated using P
