Problems solved by technology

Therefore, in the conventional split-core dual-rotor motor, the split-type stator core is placed in the middle to form a magnetic circuit (L0) that circulates the inner rotor (2) and the outer rotor (3). , the reluctance is large, and the resulting magnetic loss is large, making it a low-efficiency structure

Embodiment Construction

[0045] The above objects, features, and advantages will become clearer from the detailed description below with reference to the accompanying drawings, so that those skilled in the art to which the present invention pertains will be able to easily implement the technical idea of ​​the present invention.

[0046] Before describing the embodiments of the present invention, it should be noted that the twin-stator / twin-rotor motor of the present invention is applied to a structure in which twin rotors are arranged between inner and outer stators.

[0047] Among them, even if an integrated rotor is arranged between the inner and outer stators in the twin-stator / double-rotor motor, in fact, the magnets required to form independent magnetic circuits for the inner and outer stators are installed inside the back yoke of the rotor. and outside, it is also possible to provide dual rotor functions facing the inner and outer stators respectively. In this twin-stator / double-rotor type motor...

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.

Description

technical field [0001] The present invention relates to a double-stator / double-rotor motor, and more particularly to a double-stator / double-rotor motor and a direct-connection driving device for a washing machine using the same. The double rotors are disposed oppositely between the inner stator and the outer stator, thereby forming a magnetic circuit having magnetic circuits shortened for the inner and outer stators, thereby improving the efficiency of the motor. Background technique [0002] BLDC (Brushless DC) motors are classified according to the presence or absence of a stator core, and are generally divided into core type (or radial type) with a cup (cylinder) structure and coreless type (or axial flow type). [0003] BLDC motors with iron core structure are divided into internal magnet type and external magnet type. Among them, the internal magnet type consists of a drum-shaped stator with electromagnet structure and coil winding on a plurality of protrusions formed o...
