Note:

Temperature rise:
The losses occurring in the motor are converted into heat (thermal energy). This is the reason that
permissible limit temperature rises are defined for windings and other mechanical parts and components of
the motors. The temperature rise of the motor is defined as the difference between the temperature of a
motor component (e.g. rotor winding) and the temperature of the cooling medium (e.g. ambient air
temperature) (EN 60034-1). The temperature rise determined by the motor manufacturer by making the
appropriate measurements is the difference between the temperature of the winding at the end of the
measurement and the temperature of the cooling medium.

: Temperature rise
: Temperature at the end of the measurement
: Cooling-medium temperature

−

The permissible temperature rises of the windings is classified in insulating classes. The insulating class
valid for the particular motor is specified on the motor rating plate.

The following points should be carefully observed:
-

The temperature rises of the stator/rotor winding are only applicable for sinusoidal operation (basic
fundamental).

The temperature of stator/rotor winding rises when the motor is fed with a sinusoidal voltage as well as
also losses (modulation losses, losses due to harmonics) caused as a result of drive converter
operation.

The value may only be modified if the motor is in the cold condition (ambient temperature). The motor
identification run should be carried-out after the value has been changed.
