Motors of this power range are not available as standard units. Consult the
motor manufacturer. n.a.
Availability of du/dt filter and common mode filter by drive type
See chapter Common mode, du/dt and sine filters (page 227) .
Additional requirements for explosion-safe (EX) motors
If you will use an explosion-safe (EX) motor, follow the rules in the requirements table
above. In addition, consult the motor manufacturer for any further requirements.
Additional requirements for ABB motors of types other than M2_, M3_, M4_, HX_
and AM_
Use the selection criteria given for non-ABB motors.
Additional requirements for the regenerative and low harmonics drives
It is possible to increase the intermediate circuit DC voltage from the nominal (standard)
level with a parameter in the control program. If you choose to do this, select the motor
insulation system which withstands the increased DC voltage level.
Additional requirements for ABB high-output and IP23 motors
The rated output power of high output motors is higher than what is stated for the
particular frame size in EN 50347 (2001).
This table shows the requirements for protecting the motor insulation and bearings in
drive systems for ABB random-wound motor series (for example, M3AA, M3AP and
M3BP).
