Motor assembly

A motor assembly includes an impeller inside a motor assembly housing, a motor including a rotor including a rotor shaft rotatable with the impeller and a pair of stators disposed facing each other across the rotor while electromagnetically interacting with the rotor to rotate the rotor shaft, and a motor housing inside the motor assembly housing that fixes the pair of stators relative to the rotor.

Vacuum cleaner with motor assembly

A motor assembly having an internal channel passing an interior of a rotor, and a method for producing the same are provided. The motor assembly includes an adhesive flowing along the internal channel, and the rotor can be firmly coupled and improving durability and production efficiency of the rotor.

Motor assembly and method for providing the same

A vacuum cleaner having an improved structure capable of enhancing suction performance includes a suction unit provided in a main body, the suction unit including an impeller disposed to suck air by rotating about an axis thereof, and a diffuser disposed to guide air discharged from the impeller. The diffuser includes an inner casing, an outer casing disposed to be spaced apart from an outer circumference of the inner casing and to form a path through which the air discharged from the impeller flows, and a plurality of vanes disposed at the inner casing to guide the air discharged from the impeller to the path, and the plurality of vanes protrude toward the outer casing to cross at least a part of the path.

Vacuum cleaner

A motor includes a control part assembly having an air inlet through which air is inlet, an air flow path configured to communicate with the air inlet, and a printed circuit board; and a motor part assembly having a stator configured to generate magnetic flux when a current is applied, a rotor structured to be rotated while interacting with the stator electromagnetically, a motor shaft provided to be rotated together with the rotor, and an impeller coupled to the motor shaft and provided to be rotated to generate air flow, and is configured to be detachably coupled to the control part assembly. Through the structure as such, the performance of the motor may be improved.

Motor

A motor having a structure capable of achieving an enhancement in durability and a washing machine, to which the motor is applied. The motor includes a stator including a plurality of stator cores arranged in a circumferential direction, and coils respectively wound around the stator cores, and a rotor rotatably arranged inside or outside the stator. The rotor includes a plurality of rotor cores arranged in a circumferential direction of the rotor, a plurality of magnets each disposed between neighboring ones of the rotor cores, a molded body having a bridge to support the plurality of rotor cores and the plurality of magnets, and a coupler including coupling ribs outwardly extending from an outer circumferential surface of the bridge in a radial direction of the rotor, and coupling grooves formed at inner ends of the rotor cores supported by the bridge, to receive the coupling ribs, respectively.

Motor and washing machine having the same
