“Rotor Of Interior Permanent Magnet Motor, Compressor, And Refrigerating Air Conditioning Apparatus”
Abstract: Provided is a rotor of an interior permanent magnet motor equipped with: a rotor core (2); multiple permanent magnet insertion holes (5) which are formed on the outer periphery of the rotor core (2) in the circumferential direction; permanent magnet end air spaces (8) which are formed on both sides of the respective permanent magnet insertion holes (5); permanent magnets (3) which are inserted in the respective permanent magnet insertion holes (5); and multiple slits (7) which are formed on the core section located on the outer side of the permanent magnet insertion holes (5) in the diameter direction. Within an angular range of 360/(number of poles × 3) degrees from an inter pole position (9) three or more slits (7) are present and the width of the core section between the permanent magnet end air space (8) and slit (7) and the widths of the core sections between the slits (7) are gradually increased from the inter pole position toward a magnetic pole center (10).
