4 Fluid cooling

The heat produced by the motor is dissipated by the liquid cooling. If the motor is operated with a liquid-
cooling, the continuous force value increases many times in comparison with the self-cooling.

Design of water cooling

T_Flow

Flow temperature

T_Back

Return temperature

∆T

T_Back-T_Flow

T_Water

Mean coolant temperature, Formula: ( T_Back) / 2

Q_Water

Flow

∆p

Differential pressure

With the water 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.

4.1.1 Determination of the max. possible amount of cont. power dissipation Pv_Max

Example

•

Motor:

PS10-70x240U-SSC

•
