Technical data and characteristics
9.1
Explanations
The values in the following tables and characteristics are valid for motors with water
cooling and a cast winding design.
The specified motor power ratings and torques are the values that the rotor of the built-
in motor transfers to the spindle. Depending on the mechanical design of the motor
spindle, various levels of frictional losses occur (e.g. bearing losses, eddy losses, losses
at rotary glands).
The manufacturer of the built-in motors does not know the magnitude of these frictional
losses.
To calculate the net power output at the shaft, subtract the total frictional losses from
the specified values.
You must continually cool built-in motors independent of the operating mode.
