Direct Motor Mounting
Use direct motor mounting without couplings, in
order to avoid eccentricities and to provide for
zero backlash.
Figure 51: Direct Motor Mount
Direct mounted encoders do not have shafts and
are mounted directly onto the motor shaft.
Examples include hub-shaft or hollow-shaft
models with integral flexible mounts. These
have no separate shaft to shaft coupling. In
addition, there may be no need for mounting
brackets or adapters.

Motor Stub Shaft
Use hub or hollow shaft encoder with concentric
motor stub shaft and use a flexible encoder
mount rather than a flexible shaft coupling.
