Calculating the thermal power that can be dissipated by the cooler

Average density of the coolant:

in kg/m

Average specific heat capacity of the coolant:

in J/(kg K)

Temperature deviation vis-à-vis the inlet temperature:

ΔT in K

Volume flow rate:

in m

Coolant intake temperature

The intake temperatures must be selected in such a way that no condensation forms on the

surface of the motor. Condensation can lead to corrosion in the machine.

- 2 K

The motors are designed in accordance with DIN EN 60034–1 for operation at coolant

temperatures of up to 35°C (rated value of the coolant intake temperature). If the intake

temperature is different, the continuous motor current changes as shown below:
