Machine sets

To equip laboratory facilities Johannes Hübner Giessen supplies sophisticated machine sets consisting of all classic machine types. The combination of DC machines, asynchronous machines and synchronous machines (separately excited or permanent (magnet) excited) are bolted to a base plate with speed and torque measuring devices. This ensures rapid start-up and flexible handling qualities within the laboratory area. Utilizing the motor-generator-units manufactured by Johannes Hübner Giessen it is possible to determine all characteristic machine curves.

 
 
 

Determinable machine curves

  • Torque-speed curve
  • Power-speed curve
  • Efficiency-power curve
  • Synchronous motors with sensorless speed control
  • DC compound and shunt-wound machines
  • Starting performance of three-phase current, slipring motors with starting resistors in rotor circuit
  • Synchronize a separately excited, three-phase synchronous machine with the mains following an asynchronous start-up with own squirrel cage damper
  • Mains simulation in power range up to 6 kVA / 50 Hz
