MOTOR, STATOR CORE AND ROTOR CORE, AND MANUFACTURING METHODS OF MOTOR, STATOR CORE AND ROTOR CORE

摘要

PROBLEM TO BE SOLVED: To provide a motor having high motor efficiency.;SOLUTION: The motor has a stator 10, including a stator core 22 for excitation and a rotor 14 disposed in the stator 10, wherein an external magnetic field 32 is generated from the stator core 22, almost in parallel with the rotating shaft of the rotor 14 and the rotor 14 is rotated by the external magnetic field 32. The stator core 22 includes a layered product made of a steel plate, which is formed into a winding shape and is arranged so as to sandwich the rotor 14 in the direction of the rotating shaft.;COPYRIGHT: (C)2004,JPO
