Abstract :
The characteristics of electrical machines are influenced by the manufacturing process. It is therefore important to test the compliance of the required specifications as a first instance of monitoring. In order to develop a reliable end-of-line test it is essential to determine the statistical spread caused by manufacturing tolerances. This paper presents a statistical evaluation of the influences of non-ideal manufacturing. Simulation and measurement are being applied and compared.
