Stator Tester BST-SA

• Non-destructive testing of the magnetic properties of stators
• Quality control of unwound stators in seconds, irrespective of size
• Fully automatic measuring station, safety light barrier
• Time-consuming manual preparation of samples is no longer necessary
• Integration into production line, 100 % testing possible
• Interactive recording of measuring data which can be saved in external programmes
• Identification of all relevant measuring values

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

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).
