ROTATING ELECTRICAL MACHINE

摘要

According to the present invention, permanent magnets (32, 33) are disposed so that a straight line along the radial direction passing through the center part in the circumferential direction and the output-side rotor center axis of the permanent magnet (32), and a straight line along the radial direction passing through the center part in the circumferential direction and the output-side rotor center axis of the permanent magnet (33), are not aligned with each other; and the residual magnetic flux density (Br1) and magnetic pole face width (W1) of the permanent magnet (33), and the saturated magnetic flux density (Js) and magnetic path width (L) of a rotor core (53), are designed to satisfy the condition Js × L < Br1 × W1. Using this invention, the magnetic flux passing between the adjacent stator-side magnetic pole faces (33b) of the permanent magnet (33) flows out of the magnetically saturated rotor core (53) to the stator core (51), and the electrical angle at which the interlinkage magnetic flux to the stator winding (20) is at the peak changes.
