4 Fluid cooling

With liquid cooling, the heat dissipated in the motor is carried away by the cooling medium (e.g. water).
Compared to self-cooling, the continuous rated power of the motor is increased many times over.

Design of water cooling

T_Flow Flow temperature
T_Back Return temperature

T_Back-T_Flow
T_Water Mean coolant temperature (T_Flow + T_Back) / 2
Q_Water Flow
∆p
Differential pressure
With the fluid cooling, the coolant is passed through the cooling circuit of the motor flange.
Starting from the adjusted mean coolant temperature T_Water all other parameters of the cooling circuit may
be dimensioned based on the diagrams referred to:
T_Water → Pv_Max → Q_Water →  p
The design is illustrated by an example in the following.
