Note 4: Non-ABB high-output and IP23 motors
The rated output power of high output motors is more than what is stated for the
particular frame size in EN 50347:2001. The table below shows the requirements for
random-wound and form-wound non-ABB motors with nominal power less than
350 kW. For larger motors, consult the motor manufacturer.
Note 5: HXR and AMA motors
All AMA machines (manufactured in Helsinki) for drive systems have form-wound
windings. All HXR machines manufactured in Helsinki starting 1.1.1998 have form-
wound windings.
Note 6:
ABB motors of types other than M2_, M3_, HX_ and AM_
Use the selection criteria given for non-ABB motors.

*** If the intermediate DC circuit voltage of the drive is increased from the nominal level by resistor
braking, check with the motor manufacturer if additional output filters are needed in the applied
drive operation range.
