INTERIOR PERMANENT MAGNET SYNCHRONOUS MOTOR
In the rotor core, three or more magnet housing holes for housing magnets are formed in the circumferential direction, and when it is assumed that a stack thickness of the rotor core is X, a stack thickness of the stator core is Y, a sectional area of a core portion surrounded by a line connecting m...

| Zusammenfassung: | In the rotor core, three or more magnet housing holes for housing magnets are formed in the circumferential direction, and when it is assumed that a stack thickness of the rotor core is X, a stack thickness of the stator core is Y, a sectional area of a core portion surrounded by a line connecting midpoints of an inner diameter side surface of each of the magnet housing holes is S3, a sectional area of an outer-peripheral-side core portion provided between an outer diameter side surface of each of the magnet housing holes and an outer periphery of the rotor core is S2, a sectional area obtained by subtracting the sectional area S2 and the sectional area S3 from a sectional area of the rotor core is S1, the rotor stack thickness is formed so as to satisfy the relation of X>Y and X |
