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 braking applications
When the motor brakes the machinery, the intermediate circuit DC voltage of the
drive increases, the effect being similar to increasing the motor supply voltage by up
to 20 percent. Consider this voltage increase when specifying the motor insulation
requirements if the motor will be braking a large part of its operation time.
Example: Motor insulation requirement for a 400 V AC line voltage application must
be selected as if the drive were supplied with 480 V.
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 ABB
random-wound motor series (for example, M3AA, M3AP and M3BP).
