Title:
DOUBLE-STATOR/DOUBLE-ROTOR MOTOR AND DIRECT ACTUATOR FOR WASHER USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/162500
Kind Code:
A2
Abstract:
The present invention relates to a double-stator/double-rotor motor and a direct actuator for a washer using same, and aims to provide a double-stator/double-rotor motor and a direct actuator for a washer using same, which can promote increased efficiency by disposing a double rotor, having magnets coupled to the inner circumferential surface and the outer circumferential surface of a back yoke, between an inner stator and an outer stator so as to face same. To this end, the double-stator/double-rotor motor of the present invention comprises: a rotor provided with a first permanent magnet mounted on the inner circumferential surface of the back yoke and a second permanent magnet mounted on the outer circumferential surface of the back yoke; an inner stator facing the first permanent magnet and having a gap therebetween, which generates a magnetic field that rotates the rotor; and an outer stator facing the second permanent magnet and having a gap therebetween, which generates a magnetic field that rotates the rotor.
