ABSTRACT:
A core conveyor system for electric motor manufacturing apparatus, including a core weighing station for improving the accuracy of stock measurement in manufacturing electric motor stator and rotor laminated stacks or cores from sheet stock. Stock is initially measured to determine a measured stack thickness The weight of the manufactured stack is used to calculate the thickness of the stock material used. The calculated thickness is used to recalibrate the measured stock thickness. The weight of the stack, if not between a selected maximum and minimum values, determines if the height of the manufactured stack is acceptable. The core conveyor also includes secondary stations for other core manufacturing operations.
