Title:
MULTI SPINNING MOTOR USING 3D MOLDING CORE
Document Type and Number:
WIPO Patent Application WO/2013/077484
Kind Code:
A1
Abstract:
The present invention relates to a multi spinning motor using a three-dimensional (3D) molding core. Particularly, the multi spinning motor using the 3D molding core includes: a first rotor; a first stator disposed within the first rotor; a second rotor disposed within the first stator; a second stator disposed within the second rotor; a third rotor disposed within the third stator; and a shaft disposed within the third rotor. At least one stator core of the first stator and the second stator may be molded in a 3D shape by compressing a powder material to reduce the volume of the motor. In addition, the core of the motor may be easily manufactured to simplify the manufacturing process of the motor.
