Precision ceramic spindles have re-defined small motor positioning systems. This latest example of precision linear positioning with the use of DC motor and encoder technology also uses ground ceramic surfaces that provide silky smooth motion almost completely devoid of the slip stick phenomenon.
Ceramics now play a key role in positioning systems that require high accuracy and efficiency from DC motor and gearhead driven systems. The maxon motor ceramic linear drives feature a specially developed ceramic glide surface (CGS) that gives longer lifespans in automation systems with dynamic sliding movements. The linear systems with ceramic components are suitable in areas of strong electric fields or vacuum. The hardness and surface structure of the CGS improves wear resistance over traditional materials also. Power transmission or chemically aggressive environments, cleanrooms, high ambient temperatures or simply long life can be application requirements that need the advantages of ceramic materials. The zirconia also shares many properties with steel such as elasticity and expansion. Because of this it can also be used within the gearhead alongside traditional steels and even the DC motor shaft is often ceramic enabling commutation components to be embedded into the nonconductive material providing smaller and more robust systems.

Robocup 2014 is a robotics competition attended by more than 2000 researchers and students from all over the world. In the past maxon motor has been pleased to be associated with Robocup. In 2013, Nirmal Giftsun and Alexander Moriarty from the Bonn-Rhein-Sieg, University of Applied Sciences, entered their youBot, containing flat motors by maxon motor, in the Robocup@work category. The youBot was a fully autonomous robotic using only sensors and algorithms to find certain objects on an obstacle course and return them to a designated area.
