Abstract

The present invention discloses a cast aluminum fan blade structure for washing machine motor rotors, which comprises motor rotor cast aluminum and a shaft coupling. Wherein, both end faces of the rotor cast aluminum are formed with a plurality of fan blades. All these fan blades are evenly and circumferentially arranged. Due to the cast aluminum on both end faces of the rotor cast aluminum, double-sided fan blades are formed, thus decreasing fan blade height and increasing annular end area. Therefore, the present invention increases motor start torque, reduces temperature rise and improves motor performance index. The motor cast aluminum fan blade structure can be applied to dish washer and other equipments.

Description

technical field [0001] The invention belongs to a washing machine motor rotor, in particular to a washing machine motor rotor cast aluminum fan blade structure capable of forming double-sided fan blades, increasing the area of ​​the end ring and reducing the temperature rise of the motor. Background technique [0002] Generally speaking, a drum washing machine is a device that washes the laundry by putting detergent, washing water, and laundry into the drum, and rotating the drum by a driving force of a motor. Such a drum washing machine has the advantages of minimizing the damage to the laundry, and the laundry is not easily entangled, and has the advantages of beating and scrubbing. [0003] The drum washing machine generally includes: an outer tub capable of storing washing water is arranged on the inner side of the casing, and a drum into which washings can be put is arranged on the inner side of the outer tub. A shaft that transmits the driving force of the motor to th...
