Suction hood

A fan is provided. The fan has a motor and a first rotating shaft. The motor has a stator assembly, a rotor and a winding. The stator assembly has a stator yoke portion and a stator tooth detachably connected to each other. The winding is wound on the stator tooth. The stator yoke portion has a stator yoke slot and/or a stator projection, adapted to the shape of the stator tooth. The stator tooth axially pass through the stator yoke slot and/or the stator projection to form a stator core. A first fan blade is arranged at an end of the first rotating shaft to rotate the first fan blade when the first rotating shaft rotates.

An outdoor unit for an air conditioner, and an air conditioner are provided. The outdoor unit has a housing and a draught fan. The housing is provided with a first air exchange port and a second air exchange port. The draught fan is arranged in the housing and located between the first air exchange port and the second air exchange port. The draught fan has an electric motor, a first fan, and a second fan. The electric motor has two rotors which rotate independently of each other, and a first output shaft and a second output shaft connected to the two rotors respectively. The first output shaft and the second output shaft are respectively fixedly connected to the first fan and the second fan for driving the first fan and the second fan to rotate independently of each other.

A driving system having a hollow shaft, a solid shaft arranged in the hollow shaft, a stator, a rotor connected to the hollow shaft, a clutch mechanism selectively engaged to one of the stator and the rotor, and a speed reduction mechanism having a planetary carrier assembly engaged to the clutch mechanism, and a planetary gear train connected between the solid shaft and the rotor, wherein where the clutch mechanism is engaged to the stator in a transmission manner, the planetary carrier assembly is connected with the stator, and the rotor drives the solid shaft and the hollow shaft to operate at a differential speed, and where the clutch mechanism is engaged to the rotor in the transmission manner, the planetary carrier assembly is connected with the rotor, and the rotor drives the solid shaft and the hollow shaft to operate at a same speed by the planetary gear train.

Driving system of drum washing machine and drum washing machine

An electrical fan and an electric appliance are provided. The fans has a driving structure, an impeller, a wind hood and a diffuser. The impeller has a cover plate installed on the driving structure. The wind hood is covered on the impeller and has an air inlet and an air outlet communicated to each other. The diffuser is located at one end of the impeller facing the air outlet. The diffuser has a first protrusion connected to the driving structure. The first protrusion protrudes in a direction of the wind hood. The diameter of an end of the first protrusion adjacent the cover plate is smaller than the diameter of an end away from the cover plate. The diffuser has an inner ring arm connected to the first protrusion and an outer ring arm sleeved outside the inner ring arm.

Fan and electric appliance

A motor and a fan are provided. The motor has a stator assembly, two mutually independent rotor assemblies, and two mutually independent rotating shaft assemblies. The stator assembly has a stator core and two groups of mutually independent windings. The rotor assemblies are oppositely and coaxially arranged on two axial sides of the stator assembly and form an axial air gap with the stator assembly. The two rotor assemblies are configured to rotate independently. The two mutually independent rotating shaft assemblies are coaxially connected with the two rotor assemblies, respectively, and protrude in a direction of the same side away from the stator core along the axial direction of the motor.

Motor and fan

The present disclosure provides a bearing assembly, a rotor assembly and a draught fan. The bearing assembly has a shaft sleeve and a shaft extending through the shaft sleeve. An inner wall of the shaft sleeve is provided with two grooves in a circumferential direction. The shaft is provided with two channels corresponding to the two grooves respectively. The channels and the grooves form two raceways. Multiple rolling bodies are disposed between the shaft and the shaft sleeve and movable in the raceways. The shaft sleeve has an outer diameter of 13 mm, and a portion of the shaft extending within the shaft sleeve has a diameter of 5 mm.
