Your benefits

HÜBNER Berlin, now Baumer Hübner, has stood for robust tacho generators for almost 70 years and still supplies a wide variety of models to machine manufacturers and spare parts in OEM quality. Even though analog tacho generators have long since been replaced by digital rotary encoders in modern control concepts, LongLife tacho generators still today stand out as an alternative due to their following properties:

  • Special signal quality and service life
    • LongLife commutator thanks to silver track with constantly low contact resistance for high signal quality
    • Specially adapted brushes for maintenance-free operation and long service life
    • Wide adjustable speed range
  • Cost effective
    • Signal transmission with two-core cable, requiring no electrical auxiliary energy and power supply
    • Cost-effective complete package of tacho generators, cable and evaluation electronics
  • Reliable and safe
    • Real-time detection of speed and direction of rotation thanks to analog signal technology
    • Highest availability and unmatched service life under the toughest ambient conditions
    • Proven HeavyDuty principle, bearing at both shaft ends, HeavyDuty connection technology
  • Reliability in any environment
    • Extremely resistant housing with large wall thickness, outstanding corrosion protection, lasting impermeability concept
    • Wide temperature range from –30 °C … +130 °C 
    • Reliable protection against bearing damage
    • Shaft with bearings at both ends, generously dimensioned bearings with large bearing spacing, bearing load reserve capacity for large radial / axial shaft loads
  • Flexible and future-proof
    • Combinations with common shaft are possible:  tacho + rotary encoder, tacho + speed switch
    • Matching spare parts in OEM quality, even for obsolete models, other makes and special designs
       

Applications

Analog tachometers (tacho dynamos, DC tacho generators), usually called “tachos” for short, are devices with an output voltage proportional to the speed. They generate the output voltage by means of a generator, therefore do not require any electrical auxiliary energy and combine high signal dynamics and robustness.

In drive technology, tachos are used to record the actual speed value, for example in the following areas

  • Elevators
  • Escalators
  • Cable cars
  • Rolling mills
  • Presses
  • Crane and lifting systems
