Technical data and characteristics
9.1
Explanations
Built-in motors must be continually cooled independent of the operating mode.
Note
The characteristic curves and specified values are valid for water cooling and a cast winding
design.
Note
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 level of friction losses is not known to the manufacturer of the built-in motors.
The motor powers and torques specified in this documentation refer to the values that the
rotor of the built-in motor transfers to the spindle.
To calculate the net power output at the shaft, subtract the total friction losses from the
specified values.
