Operating principle

The testing station consists of a testing cage made from aluminium profiles. The front section is fitted with a safety light shield. This guarantees very quick operating processes.

The stator package is fixed via a horizontal drill hole into a small prism. When the area of the safety light barrier is clear the testing process can be started by using the start button. Then a u-shaped bracket with 23 windings moves into the stator and makes contact with the opposite side. The measurement is started with a start signal.

If the measuring result is positive (the stator corresponds to the norm) the u-shaped bracket recedes and the measuring sample can be removed. If the result is negative (the stator does not meet the norm) the u-shaped bracket remains closed – a lamp lights up – and can only be released by activating a switch manually.

Measuring categories

  • Specific hysteresis loss [W/kg]
  • Maximum polarisation [T]
  • Effective polarisation [T]
  • Maximum field strength [A/m]
  • Effective field strength [A/m]
  • Remanence [T]
  • Coercive field strength [A/m
  • Permeability
  • Spezific apparent output [VA/kg]
  • AC hysteresis curve

The measured values are displayed on a monitor and can be printed out. Transmission to the PC is possible via an ARCNET interface. BROCKHAUS® MPG Expert 2.x software controls the equipment and displays the results (Windows 98/ME/NT/2000/XP).
