The flanges are assigned to the frame sizes as FF with through-holes in DIN EN 50 347.
A-flanges acc. to DIN 42 948 are still valid.
1) 60 Hz is available for 2-pole
1LG4 and 1LG6 motors with
frame size 315 L on request.
2) The 1LG4/1LG6, 1MA6, and
1MJ7 motors with frame sizes
between 225 S and 315 L are delivered
with two bolted eyebolts
(four eyebolts for 1LG6 318) according
to IM B 5, one of which
may be repositioned acc. to
IM V 1 or IM V 3. Care must be
taken to avoid stress perpendicular
to the eyebolt.
3) With frame sizes between 180 M
and 225 M, the 1LA5 motors are
available with two additional eyebolts;
please state order suffix "Z"
and Order Code K32.
4) Frame size 450, 2-pole, 60 Hz
not available.
5) 60 Hz design is not available for
