The emergence of DD motor technology has broken the convention that the roller consumes more power than the pulsator. DD direct drive technology has changed the previous method of using a belt as a medium, and it is directly driven by a motor. The efficiency of the DD motor is 16 times that of the traditional motor, and the energy saving is about 35%, so that the drum washing machine is not inferior to the pulsator washing machine in energy consumption. At the same time, the DD direct drive technology also solves the problems of large vibration and noise of the drum washing machine. What is even more surprising is that the thinnest drum-type washing machine using DD motors is only 44 mm in thickness and can be easily embedded in various overall cabinets. DD motors remove parts such as belts and pulleys. The shape allows the diameter and depth of the inner drum of the drum of the washing machine to achieve a large capacity easily without changing the volume of the washing machine. As the top leader in achieving ultra-thin, the ultra-quiet work of DD motors is even more commendable.
DD Motor are used in intelligent drying drums with different capacities such as 5.2, 7, 9, 10, and 12 kg. The products have the advantages of strong power, long life, quietness, and energy saving. Due to the excessive noise of washing machines, they are annoying to family members. As well as the rest of the neighbors, they often cannot be used on demand like home appliances such as refrigerators and air conditioners. The ultra-thin drum washing machine with DD motor directly drives the inner tub, which greatly improves the stability of the motor work, thereby achieving It has ultra-low vibration and ultra-quiet working state.
Excellent: low energy consumption, high efficiency, low noise, low failure rate, large amount of single washing.
Disadvantages: inconvenient maintenance, the temperature of the motor exceeds 70 ° C for a long time, the speed change is about -2% to 10%, and the speed variation between the motor and the individual motor is large.
