Note 2: Explosion-safe (EX) motors
The motor manufacturer should be consulted regarding the construction of the motor insulation and
additional requirements for explosion-safe (EX) motors.
Note 3: High-output motors and IP 23 motors
For motors with higher rated output than what is stated for the particular frame size in EN 50347 (2001)
and for IP 23 motors, the requirements of ABB random-wound motor series M3AA, M3AP, M3BP are
given below. For other motor types, see the
range 100 kW < P

Note 4: 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 5: ABB motors of types other than M2_, M3_, HX_ and AM_
Use the selection criteria given for non-ABB motors.
Note 6: Resistor braking of the drive
When the drive is in braking mode for a large part of its operation time, the intermediate circuit DC
voltage of the drive increases, the effect being similar to increasing the supply voltage by up to
20 percent. The voltage increase should be taken into consideration when determining the motor
insulation requirement.
Example: Motor insulation requirement for a 400 V application must be selected as if the drive were
supplied with 480 V.
Note 7: Drives with an IGBT supply unit
If voltage is raised by the drive (this is a parameter selectable function), select the motor insulation
system according to the increased intermediate circuit DC voltage level, especially in the 500 V supply
voltage range.
