Motor Encoder

For higher positioning and speed control, DongHui provides a wide range of encoders to combine with the complete portfolio of DongHui DC, brushless, and stepper motors. In the area of encoders, DongHui offers 2- and 3-channel incremental magnetic and optical encoders with standard quadrature resolution from 16 to up to 10,000 pulses per revolution or single-turn absolute encoders with a resolution of up to 4 ,096 steps.

DongHui encoders: Optical encoders
Optical encoders are characterised by a very high position and repeat accuracy as well as a very high signal quality due to the precise measuring element. Furthermore, they are insensitive to magnetic interference. In optical encoders, a code disc with a measuring element is used that is attached to the shaft of the motor. A distinction is made here between reflective and transmissive optical encoders.

Encoder From DongHui

Magnetic and optical incremental encoders

Incremental encoders with high accuracy with modular design

The incremental encoders from DongHui are constructed according to optical or magnetic principles as well as in a single-chip version. The encoder supplies two 90° phase-shifted square wave signals with up to 10,000 pulses. In the 3-channel version, an additional index pulse is available per motor revolution.

Absolute encoder for commutation, rotational speed control and position control

Absolute angle information immediately after switching on
In combination with the DongHui DC-motors, the absolute encoder is ideal for commutation, rotational speed and position control. Absolute means each shaft position within a revolution is assigned a unique angular value through the encoder.
