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 IP23 motors, the requirements of ABB random-wound motor series (for example M3AA, M3AP,
M3BP) are given below. For non-ABB motor types, see the basic table above and apply the
requirements of range
100 kW <
P
N
< 350 kW
to motors with
P
N
< 100 kW. Apply the requirements of
range
P
N
> 350 kW
to motors within the range
100 kW <
P
N
< 350 kW
. In other cases, consult the
motor manufacturer.
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.
ABB motors of types other than M2_, M3_, HX_ and AM_
Use the selection criteria given for non-ABB motors.
When DC link voltage is increased with parameter settings
If the intermediate circuit DC voltage is increased with the IGBT supply control program parameter
settings, select the motor insulation system according to the increased DC voltage level, especially in
the 500 V supply voltage range.
Calculating the rise time and the peak line-to-line voltage
The peak line-to-line voltage at the motor terminals generated by the drive as well as the voltage rise
time depend on the cable length. The requirements for the motor insulation system given in the table
are “worst case” requirements covering installations with 30 metre and longer cables. The rise time can
be calculated as follows: t = 0.8 ·
