dc motor

Flexmount are used to prevent the equipment shaft runout from grinding the encoder bearings. Either the rotor or the stator must be allowed some flexibility to account for shaft runout. Sometimes the encoder shaft is hard-coupled to the mating shaft, therefore the needs for a flexmount.

Tether arms are used to mount hollow shafted encoders to a standard NEMA motor face or other structure that is stationary in relation to the encoder shaft.  Couplings do for shafted encoders, what tether arms do for hollow-shaft encoders. Either the shaft can be rigidly fixed and allow the encoder body to move to accommodate runout, or the other way around.

Shafted encoders usually have the body rigidly fixed and use a flexible coupling to accommodate runout.  Conversely, hollow shaft style encoders have the bore fixed to a rotating shaft and use a tether arm to accommodate runout.
