In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are:
Simple mounting
Short overall length
High natural frequency of coupling
Hollow-through shaft possible
Rotary encoders with integral bearing that are conceived for separate shaft coupling are designed with a solid shaft. The recommended coupling to the measured shaft compensates radial and axial tolerances. Angle encoders for separate shaft couplings permit higher shaft speeds.
Rotary encoders without integral bearing operate without friction. The two components - the scanning head and the scale disk, drum, or tape - are adjusted to each other during assembly. The benefits are:
Large diameter of hollow shaft
For high shaft speeds
No additional starting torque

Hohner Automazione encoders are high precision position/speed transducers. They are used to sample these quantities
on a revolving axle. The encoder converts the input analog signal to digital signal, so that it can be handled by a computer device. The conversion is carried out by a coded wheel, integral with the transducer shaft, read by a photoelectronical system. |

Angle Encoders without Integral Bearing
The HEIDENHAIN ERP, ERA and ERO angle encoders without integral bearing are intended for integration in machine elements or components. They operate without friction and permit high accuracy. This makes them particularly attractive for high-precision angle measuring tables and precision devices in angular metrology. The attainable system accuracy depends on the eccentricity of the graduation to the drive shaft bearing, as well as the radial runout and wobble of the bearing.

Absolute encoders are devices used to measure lengths or angles and are used as distance gauges in machine tools, in handling and automation technology and on testing units.
Absolute encoders
These output positional information in the form of a numerical value (code). This numerical value is unique across the entire resolution range of the absolute encoder. For this reason no initial reference run is required, as is the case with incremental encoders.
With rotary encoders, a distinction is made between single-turn encoders, which provide a resolution on just a single rotation and then revert to 0, and multi-turn encoders that provide a resolution over several rotations. A further distinction is made between optical and magnetic encoders. |
