Latest Patents

Panu Hava holds a patent for a rotor of an induction machine and a method for assembling a cage winding of the rotor. This invention includes a rotor core structure and a cage winding, which consists of rotor bars placed in slots of the rotor core structure and end-rings connected to the ends of the rotor bars. The unique aspect of this design is that the ends of the rotor bars are attached to the openings of the end-rings by expanding the ends of the rotor bars in transverse directions. This expansion is caused by an axial press directed to the ends of the rotor bars. The materials used in this invention are carefully selected to prevent unwanted shape deformation of the end-rings during the assembly process. The rotor bars are made of a softer material, such as copper, while the end-rings are typically made from a copper alloy with additions of chrome and zirconium.
