Industrial types
Shaft fixing is done through a clamping ring either on the flange or cap side. As a rule,
flange side clamping is better for smaller motors as the available shaft stub is correspondingly shorter.
On the other hand, cap side clamping is easier when there is sufficient shaft length
available.
In order to compensate for axial and radial shaft eccentricity as well as any angle offset, the
encoder flange must not be rigidly mounted. Please mount the flange with a flexible stator
coupling (e.g. hubshaft with tether) as torque support.
There are two flexible mounting plates:
• A flexible hubshaft with tether (A) for higher levels of play and lower requirements
for accuracy.
• A rigid hubshaft with tether (N) for reduced play and rigid connection with reduced
swing angle. This is suitable in the case of higher accuracy and dynamics requirements.
