New magnetic sensors on the SA market
June 2006
Sensors & Transducers
Previously, drives with a large shaft diameter, such as torque motors, have often been fitted with encoders mounted to one side and driven through toothed belts, for the acquisition of the rotor position and speed. This old method had several distinct disadvantages. The toothed profile of the belt would show up in the signal being measured and the elasticity of the toothed belt also had the potential to lead to problems in the control loop - and then this solution required on-going maintenance.
Hubner Berlin's new robust, maintenance-free solution is based on a magnetic encoder mounted directly on the drive shaft. This means that there is now a direct magnetic sensing method for applications for very large diameter hollow shafts. Another advantage of this design is that a larger spacing is allowed between the sensor disk and the sensor head, thus allowing larger tolerances in the radial mounting. The device can handle axial tolerances of the drive shaft that might be caused, for example, by thermal expansion. These magnetic sensors are available as sine wave, square wave and absolute encoders, and have already been implemented for hollow shaft diameters from 50 to 690 mm.
As a partner of global encoding equipment manufacturer, Hubner Berlin, Elquip Solutions is bringing this, its latest series of magnetic sensing encoders to the local market.
