Mechanical Design Types and Mounting Rotary encoders with Integral Bearing and Stator Coupling
Benefi ts of the stator coupling: Mounting the ECN/EQN/ERN 1100 and ECN/EQN/ERN 1300 No axial mounting tolerances between shaft and stator housing for ExN 1300 and ExN 1100High natural frequency of the couplingHigh torsional rigidity of
shaft coupling
Low mounting or installation space re-
quirement
Simple installation Mounting the ERN 1000 The blind hollow shaft or the taper shaft of the rotary encoder is connected at its end through a central screw with the measured shaft. The encoder is centered on the mo-
tor shaft by the hollow shaft or taper shaft. The stator of the encoder is clamped by an axially tightened screw in the location hole. The rotary encoder is slid by its blind hollow shaft onto the measured shaft and fastened by two screws or three eccentric clamps. The stator is mounted without a centering fl ange to a fl at surface with four cap screws or with two cap screws and special washers. ERN/ECN/EQN 1300
ERN/ECN/EQN 1100Stator coupling ECN/EQN/ERN rotary encoders have inte-grated bearings and a mounted stator cou-
pling. The encoder shaft is directly connect-
ed with the shaft to be measured. During angular acceleration of the shaft, the stator coupling must absorb only that torque caused by friction in the bearing. ECN/
EQN/ERN rotary encoders therefore pro-
vide excellent dynamic performance and a high natural frequency. Mounting accessories for the ERN 1000Washer For increasing the natural frequency f 45 mm
