Bearingless encoders

Our bearingless, and therefore contactless, rotary encoders are the perfect choice for applications that require continuous, precise measurements with minimal maintenance. They operate entirely without internal bearings as a two-part system consisting of a sensor and Position marker separate Position marker. The contactless measurement method ensures consistently precise measurements and eliminates the wear and tear typically associated with conventional systems.

The absence of internal bearings ensures long-lasting and consistent performance over extended periods of operation. These sensors are housed in extremely robust enclosures that provide protection against environmental influences and mechanical damage, even under extreme operating conditions. Bearingless encoders prove to be particularly efficient in environments that require a minimum of system downtime and deliver reliable performance.

Another hallmark of these technologies is their high degree of adaptability during installation, without compromising accuracy or reliability. This versatility makes our bearingless encoders the ideal choice when continuous monitoring and flexible system integration are critical.

Key advantages of brushless encoders

• Long service life: The two-part system, which does not have its own bearings, minimizes wear and ensures the longevity of the components, thereby significantly reducing maintenance requirements.
• High flexibility: Supports a wide range of installations and applications thanks to its ease of use.
• Exceptional durability: Protective measures against dust and moisture maximize the sensors' service life and operational reliability.

Typical applications for bearingless encoders

• Industrial Automation: Thanks to their continuous performance without the need for readjustment or recalibration, they ensure extended operating times; ideal for environments with exceptionally high hygiene and safety standards.
• Conveyor Technology: In conveyor technology, the sensors precisely monitor the speed and position of conveyor belts, ensuring cycle accuracy and preventing slippage. The wear-free measurement reduces downtime and maintenance requirements.
• Textile and packaging machinery: Here, non-contact angle sensors reliably detect the position of dancer arms, even under harsh environmental conditions. The non-contact measurement stabilizes web tension and consistently improves process quality.
• Mobile machinery: For example, in all-wheel-steering systems on forestry machines, sensors precisely detect the positions of the front and rear axles so that the axles can be fully synchronized. This improves directional stability, maneuverability, and safety on varying terrain.

Novotechnik’s bearingless—and thus non-contact—encoders combine state-of-the-art technology with a robust design to deliver consistent performance across a wide range of industrial and mobile applications. They enhance the efficiency of industrial work processes, continuously improve production quality, and simultaneously reduce operating costs. Their applications are virtually limitless, making them the ideal choice for demanding environmental conditions.
