Title:
誘導電動機用回転子
Document Type and Number:
Japanese Patent JP2009516498
Kind Code:
A
Abstract:
A rotor for use in an induction motor includes a main body installed to be rotatable by having a gap inside a stator, providing a flow path of magnetic fluxes produced from the coil, and including a plurality of conductors formed on an edge region of the main body; a pair of barriers formed to pass through the main body in a manner to have a semi-spherical shape from a sectional view, base lines of the semi-spherical shape being disposed to face each other; and a plurality of permanent magnets disposed inside the individual barriers. Therefore, the permanent magnets can be easily affixed to the inner side of the individual barriers, and the loss of the magnetic fluxes is minimized, thereby improving the efficiency of the rotor.
