Table for calculating the cooling powers to be dissipated (power loss) for asynchronous motors
The values specified in the following table refer to a cooling-medium temperature of 20 °C
and S1 duty.
The cooling capacities to be dissipated at maximum speed and at rated speed are listed in
the following table. Intermediate values can be linearly estimated proportional to the speed.
