The LG 4413ER1003A Washer Rotor Assembly is responsible for rotating the drum through the creation of a magnetic field in conjunction with the stator. This assembly uses electromagnetic induction to produce torque and the internal friction and wear of the assembly are minimized. It is made to be durable and prolong the longevity of the system by ensuring that the drum is always spinning at the right speed and with minimal vibration. It ensures that it will be able to perform its cleaning function effectively.
