THIS makes it more difficult to start on inclines, for instance. Thanks to integrated pulse multiplication, a high-resolution speed sensor from Lenord+Bauer enables more dynamic control behaviour. Rolling detection, too, benefits from the greater number of pulses.

Lenord+Bauer has developed a speed sensor for applications which place high demands on drive efficiency and driving comfort. In the GEL 2477, robustness and reliability have been combined with higher resolution. The energy consumption of the motor and the noise it generates can be reduced through torque ripple. This pays off in situations where a high torque is demanded, enabling smooth start-up even under high loads or on inclines.

The GEL 2477 acquires the rotational speed and direction of rotation directly on the motor or gear. With a measuring range of 0Hz to 25kHz, it detects even the tiniest movements of the drive just as reliably as the maximum speed. The bearing-less pick-up encoder is wear-free and long-lasting.

While standard speed sensors deliver one pulse per tooth, with the two-channel GEL 2477 sensor the resolution of the internal analogue signals is increased by a factor of two, four or eight and a greater number of pulses is achieved. This allows a significant improvement in control accuracy even with smaller target wheels with fewer teeth.
