Operating principle The BST-FA system allows fast fully-automated testing of stators in production of electric motors. It is easy to integrate with industrial and collaborative robots, as well as directly in the manufacturing lines. The stator core is placed by the robotic arm in the loading position of the table. The presence of stator is detected by the optical sensors and table rotates to bring the stator into measurement position. When the measured position is reached the pneumatic actuator closes the split coil and testing is initialized. During testing the robotic arm loads the next stator...
