CAUTION
Do not adjust the cam screws before motor shaft
mounting; bottoming out the screws, or backing
them out excessively, can lead to insufficient shaft
holding force. Thread locker is preapplied on the
cam screws.

the inside of the rotor bore before mounting. Tighten the rotor set
screws to 2 N-m using the 2mm T-handle hex wrench.
CAUTION
Use only a T-handle or torque hex wrench to tighten
set screws; using a right angle wrench will not pro-
vide enough holding force, and the rotor may slip.
STATOR HOUSING INSTALLATION
The stator housing is attached to the motor using four socket
head cap screws M10 x 0.5 x 20mm long, locating on a 150mm
bolt circle. Longer bolts (not included), are required for sandwich
installation between a motor and a brake. Install the four mount-
ing bolts using thread locker and torque to approximately 27 to
40 N-m using the 8mm T-handle hex wrench.
VERIFY ROTOR LOCATION
To ensure the rotor is properly located on the shaft: remove the
back cover if factory-preinstalled, and verify that the outer face
of the rotor is at the same depth as the alignment grooves, using
a straight edge tool. (Figure 3)
CAUTION
Do not use silicone sealants or caulk of any kind
on the motor or encoder face; these can cause mis-
alignment or sensor scraping damage. The AV115
electronics are fully sealed; water may enter and
leave the rotor area as needed. A drain hole option
is available if frequent moisture buildup is expected.
