Flange Mounting, Face Mounting; O-Ring Sealing - Kollmorgen AKMH Series Instruction Manual

13.2 Flange mounting, Face mounting

Galvanic corrosion could result in contamination of product, failure of
motor mounting and motor failure. Failure of the motor mounting could
lead to electrocution hazard due to failure of electrical terminations or the
motor cable as a result strain on the motor cable.
The motor housing is stainless steel. Avoid direct coupling of the motor to
more active metals such as aluminum or carbon steel to prevent galvanic
corrosion.
AKMH motors can be mounted either from the rear side of the flange or from the front side.
Use the optional AKMH mounting kits (➜ # 37) which will include the correct sealed screws
for flange and center shaft, to meet the hygienic requirements.

13.3 O-ring sealing

Place the FDA approved o-ring (part of delivery) to to the groove of the motor flange (see
graphics above), then press the motor to the counter flange (for example the gearbox flange)
and fix the sealed screws.
