Face mounting (flange types Cx, Hx):
The basic style for face mounting is style IM B14 according to EN 60034-7.
Mount the o-ring (FDA approved) for flange sealing.
Mounting styles IM V19 and IM B14 with cable bushing on top is not allowed in hygienic
applications.Mount the cable bushing in the "down" part of motor to promote drainage after
washdown. Add a strain relief to the cable if necessary.
Shaft
Power transmission is made through the cylindrical shaft end (with a shaft center thread).

Hygienics for food and beverage or medical applications require high level protection class.
For AKMH motors, IP69K is defined. The mechanical and electrical motor interfaces are the
most critical areas to fulfill the requirements.
The mechanical interface (flange and shaft) will usually be connected either to a machine
flange or to a gearbox. Flange sealing is done with the FDA approved o-ring.
If AKMH is connected to a machine flange with unsealed shaft region, then the shaft seal
ensures the IP69K shaft sealing. The shaft seal is an FDA approved, single lip, mineral filled
Teflon ring.

Run-in procedure of shaft seal needs to be performed to ensure rated performance of AKMH
motors. Kollmorgen recommends executing following run-in procedure:
• 30 minutes no load run at maximum speed in CW direction
• 30 minutes self-cooling of AKMH motor
• 30 minutes no load run at maximum speed in CCW direction
• 30 minutes self-cooling of AKMH motor
• This cycle should be repeated 3 times
