Off-axis encoder design

 
Easy to deal with harsh working conditions

The optical encoder code disc commonly used metal, glass, plastic and other materials. In actual installation, the distance code plate and photosensitive resistance is extremely small, any axial movement may damage the encoder. For example, in the textile industry, rapier vibration makes the motor shaft is always in vibratory state, which led to the optical encoder service life was shortened. Frequent replacement not only to improve the efficiency of the system useless, but also bring significant cost pressures. At the same time, limited by the photoelectric sensing technology, the production process of dust, debris fabric easily emit light pollution, resulting in poor optical encoder adaptability in harsh environments. The magnetic encoder does not depend on the light source, the magnetic field generated from the magnetic poles of the pollutants, the code disk is extremely rugged and thus life is often several times the optical encoder.
Furthermore, since the anti-vibration, anti-corrosion, anti-pollution, anti-jamming and wide temperature and other characteristics, magnetic encoder can be used in many conventional optical encoder can not adapt to the field.

At present, foreign markets, Timken Timken® off-axis magnetic encoder has been successfully applied to the closed-loop stepper systems and automotive EPS steering systems and other fields; in the country, injection molding machines, woodworking engraving machine, textile machinery, electrical and other waterproof environmental requirements are more demanding industrial magnetic encoder range of applications. Including highways ETC automatic railing machine, dynamic theater, revolving stage, moving fountains, electric forklifts, etc. required for the position control of common areas, as well as long-term exposure to large temperature difference between the environment situation is also very suitable off-axis magnetic encoder.
