Small motor positioning systems have been redefined by precision ceramic spindles. This precision linear positioning using DC motor and encoder technology also employs ground ceramic surfaces that provide silky smooth motion without the slip stick phenomenon.

Ceramics 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 delivers 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 also improve wear resistance over traditional materials.

Ceramic materials offer advantages in applications within power transmission or chemically aggressive environments, cleanrooms and high ambient temperatures. Zirconia also shares many properties with steel such as elasticity and expansion, allowing its use within the gearhead alongside traditional steels. Even the DC motor shaft is often ceramic, enabling commutation components to be embedded into the nonconductive material providing smaller and more robust systems.

Maxon Motor Australia can provide engineering assistance to custom manufacture precision ceramic linear positioning systems.
