The ECN 2000 angle encoders havean integral bearing, a hollow shaft and astator-side coupling. The measured shaft
is directly connected to the shaft of theangle encoder.

Electrical connection

The circular scale is firmly connected tothe hollow shaft. The scanning unit rides on
the shaft on ball bearings and is connectedto the housing with a stator-side coupling.
The stator coupling and the sealing design
greatly compensate for axial and radial
mounting errors without restricting
functionality or accuracy. This therefore
simplifies mounting. During angularacceleration of the shaft, the coupling must
absorb only the torque resulting fromfriction within the bearing. Angle encoders
with a stator coupling therefore exhibit
excellent dynamic performance.

Mounting
The housing of the ECN 2000 is firmly
connected to the mounting surface ofthe machine component via a mounting
flange and a centering collar. For coupling
to the shaft, the ECN with its hollow shaft
is press-fitted onto the motor shaft andclamped on the rotor side with threeeccentric clamps.
Materials to be used for mounting
the ECN 2000
The machine shaft and the fastening
components must be made of steel. The
material must exhibit a coefficient ofthermal expansion ofÞ = (10 to 16) · 10–6 K–1.
Additionally, the material must meet thefollowing specifications:• For a hollow shaft connection
Rm  650 N/mm2
Rp0.2  370 N/mm2• For a housing connection
