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.
