Tacho generators

Tacho generators are analog transducers for instrumentation and control technology. The task of these permanently (magnet) excited generators is to convert the speed with which they are driven into a voltage proportional to that speed. Thanks to their robust design and construction these encoders are suitable for large industrial drives such as those found in steel and rolling mills, coal mining operations, in process engineering, railways, power plants and in marine engineering.

In addition to the shorter and longer series versions it is also possible to deploy the tacho generators as double tacho generators versions or in combination with incremental encoders and overspeed limit switches.

 
 
 

Outstanding strengths of Johannes Hübner Giessen

  • Manufacture of specially dimensioned tacho generators and customized flanges and shafts to meet individual customer requirements
  • Special windings to achieve the desired speed/voltage ratio or galvanically isolated windings for measuring purposes and control tasks
  • Assembly/combination with incremental encoders or overspeed switches
  • Separately excited versions for applications with variable output voltages possible by means of excitation current
  • Robust constructions and different assembly options
  • Electrical connections via terminal boxes or connection cable
  • Very low harmonic content, very low linearity errors and temperature drift (temperature compensation up to +100 °C)
  • Available degrees of protection: IP55 to IP68
