Operating principle The BST-L system is integrated with the MPG 200 D magnetisation unit. BST-L magnetic measurements of stator teeth and back iron sections are performed using a customized sensor head. The measurement locations are defined by the user by specifying the vertical and angular positions of sensor head with respect to the stator. The positioning process of the sensor head is fully automated and controlled by the YZ scanning system and rotating table with stator holding fixture. The initial reference position of the sensor head and the stator is calibrated with the laser positioning...
