Bearingless encoders

Reliable speed measuring with magnetic sensor solution.

Bearingless encoders are the perfect alternative to bearing mounted encoders, due to their compact design and easy mounting options on almost any shaft diameter. Bearingless encoders from Kübler are already used today in drive and elevator technology, for asynchronous motors or external rotor motors, or in generators, large motors, and wind turbines. Our smart technology is available for the highest signal quality. Digital real-time signal processing compensates for possible signal errors and optimizes drive control. Design your plants, machines, or motors with Kübler!

Compact and wear-free sensor solution
  • Any resolution can be realized
  • Programmable for maximum flexibility
  • For shaft diameters up to 390 mm
  • Customer-specific solutions on request

For high signal quality

For high signal quality

If high demands are placed on signal quality, the RIM200 bearingless rotary encoders with 2 mm pole length or the RIM2000 programmable bearingless rotary encoders should be used. This requires good bearings and a stable installation process that allows an air gap of up to 1 mm.

For applications with a larger air gap

For applications with a larger air gap

If the application requires a larger air gap (up to max. 2 mm), the RIM500 bearingless rotary encoders with 5 mm pole length or the RIM5000 programmable bearingless rotary encoders are used. These also offer high performance and high signal quality.

Wide selection of magnetic rings

Wide selection of magnetic rings

Even if a high resolution can be realized for all outer diameters, it is recommended to select the largest possible diameter.

Various mounting options
