PERMANENT MAGNET EMBEDDED BRUSHLESS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a permanent magnet embedded brushless motor of high efficiency and low noise by reducing a variation in rotor position detection.

SOLUTION: A magnetic detecting element 14 detects the position of a rotor 6 in which plate-shaped permanent magnets 8 are embedded in truncated chevron shape in a rotor core 7 so that the near centers of the opposite faces of adjacent permanent magnets 8 are positioned on the same circumference. The magnetic detecting element is installed substantially at the center of the opposite faces of adjacent permanent magnets 8 in the direction of the axis of the rotor 6.
