STATOR TECHNOLOGY - PRODUCT QUALITY

Pictures of stator laminations with Y opened to allow the insertion of the copper wires, micro-structure of a slot opened and slot closed. The process of opening and closing does not damage the Y if the lamination is well heat treated.

Benefits of the stator with Y reduced. Increasing the area of electrical steel therefore increases the magnetic flux between the rotor and stator. The dimensional of the Y must exceed the minimum air gap (distance between rotor and stator).
