The standard flanges are assigned to the frame sizes as FT with threaded holes in DIN EN 50 347.
C-flanges acc. to DIN 42 948 are still valid.
The custom flange was assigned as large flange in the previous DIN 42 677.
All types of construction within the following series have equal dimensions:
IM B3, IM B6, IM B7, IM B8, IM V5, and IM V6
IM B5, IM V1, and IM V3
IM B14, IM V18, and IM V19
The motors in the standard power range are available in the standard types of construction IM B3, IM B5 or IM B14, and can be operated
in mounting positions IM B6, IM B7, IM B8, IM V5, IM V6, IM V1, IM V3 (up to frame size 160 L) or IM V18 and IM V19. Eyebolts are available
for transport and installation in a horizontal position. In conjunction with the eyebolts, for the purpose of stabilizing the position when the
motor is arranged vertically, additional lifting straps (DIN EN 1492-1) and/or clamping bands (DIN EN 12195-2) must be used. If mounting
position IM V1 is ordered, eyebolts are supplied for vertical mounting.
■On the normal rating plate, therefore, they are marked with only the basic type of construction.
■If foot-type motors larger than frame size 180 M are mounted to the wall, it is recommended
that especially the motor feet are supported.
For all motors with the shaft end pointing downwards,
the version "with canopy" is recommended;
see Section "Technical Information", "Degrees of protection".
For explosion-proof motors:
For types of construction with shaft end pointing downwards,
the version "with canopy" is mandatory.
Types of construction with shaft end pointing upwards must be
suitably covered in order to avoid that small parts
fall into the fan cowl.
(See also Section 17 DIN EN 50 014).
The cooling may not be impaired by the cover.
1) Second K16 shaft extension not
available.
2) For 1MJ6 motors only possible
for frame size 90.
3) For 1MJ6 motors only possible
for frame size 80.
