Data for precision motor cooler
Q
P,MAX
Maximum heat loss dissipated by the precision cooler when the motor is utilized up
to its rated torque M
N
and at rated temperature T
N
.
P,MIN
Recommended minimum volume flow rate in the precision cooler to achieve a
minimum temperature increase on the mounting surface of the stator with respect
to T
VORL
.
Δ
T
p
The temperature increase of the cooling medium between the inlet and return flow
circuit of the precision cooler at the operating point Q
P,MAX
and
P,MIN
can be
estimated with the following formula:
Average density of water:
ρ
= 1000 kg/m
3
Average specific thermal capacity of water: c
p
= 4.18 · 10
3
J/(kg K)
Temperature change with respect to the inlet temperature:
Δ
T
P
in K
Volume flow rate: in m
