As a rule, two cables are required for these tasks. However, if the encoder and drive controller are more than 15 m apart, the data can no longer be transmitted without interference. In this case, an output choke is therefore required for each cable - an expensive component that requires additional space in the control cabinet. In addition, chokes generate heat, so that appropriate cooling is required.Stöber has tackled these problems in cooperation with Heidenhain: Together, they have further developed Stöber's existing single-cable solution and optimized it specifically for highly dynamic applications in drag chains. Following extensive load tests, the 'One Cable Solution - OCS' now guarantees drag capability without a choke for cable lengths of up to 50 m.

The new hybrid cable is designed for the EZ and EZS series of synchronous servomotors. These can be combined with all Stöber gearboxes in direct mounting. Thanks to this product diversity and the combination options, designers can make their solutions much more compact. They receive a complete system comprising a synchronous servomotor, cable and SC6 or SI6 drive controllers.

The company's portfolio also includes rack and pinion drives. Four different series can be connected directly to the synchronous servomotors of the EZ series in all sizes. This allows the drive supplier to adapt this system to different requirements in terms of load capacity and precision. The rack and pinion drives are based on case-hardened and ground pinions with high-quality gearing and precisely matched racks from cooperation partner Atlanta. Users benefit from the advantages of direct mounting: without additional adapters, the drive units are lighter and more compact, which has a positive effect on dynamics and volume. In addition, assembly is faster.

The racing car from Rennschmiede Pforzheim contains drive components from Stöber, among others.

A completely different application can be found in a golden-blue racing car - because Rennschmiede Pforzheim, an initiative of Pforzheim University that takes part in Formula Student every year with a racing car it has developed itself, also uses technology from Stöber. In 2019, the racing team switched from the combustion engine class to the more demanding FSE (Formula Student Electric) and developed a purely electrically powered race car. Stöber supplied drive components and supported the team with a great deal of expertise.
