EMBEDDED MAGNET TYPE SYNCHRONOUS MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a low-vibration and low-noise embedded synchronous motor which suppresses the distortion of induced voltage during drive thereby making sine waves. SOLUTION: This embedded magnet type synchronous motor is composed of an embedded magnet type rotor 1 where the number of poles is P and a stator 4 which has three-phase stator winding where winding is wound into distributed winding, and the numbers of slots 5 of the stator 4 is in the relation of S=4.5P.
