Ordinary washing machines use brush motors, which transmit power through belts. They consume large amounts of energy, make loud noises, and the belts are prone to aging. The LG washing machine that adopts DD variable frequency direct drive technology realizes the direct combination of the motor and the inner tub, changing the transmission method of the traditional washing machine using belts and pulleys to drive the washing device, realizing the direct output of motor power and maximizing the efficiency of the motor. Most ordinary DD motors on the market only have a few magnetic poles. The magnetic poles are the core components that control the speed and position of the motor. The more magnetic poles, the smoother the motor rotates. After research and development, LG Electronics has increased the number of magnetic poles of the DD variable frequency direct drive motor to 48, which is far more than other following products on the market. It has made a breakthrough in improving the precision and stability of controlling the drum operation. The excellent performance of the DD variable frequency direct drive motor, It not only minimizes unnecessary energy loss during motor operation, but also minimizes the sound when the washing machine is working. The DD variable frequency direct drive motor used in LG washing machines dares to promise consumers a 10-year warranty, which is undoubtedly the most reliable guarantee that consumers trust.
