Haier washing machine uses Emerson motor.
Emerson (American Emerson Electric Company) was founded in St. Louis, Missouri. At that time, Emerson Electric was a motor and fan manufacturer, and Emerson developed from a regional manufacturer to a global technology solution giant.
At present, the series motors and variable frequency motors do not directly drive automobiles, and the brushes of the series motors are worn, and the noise is high. The belt variable frequency motors have no carbon brushes, and the transmission and motor are integrated, so the noise is lower than that of the series motors and the radiation is lower.

Note:
There are three types of washing machines, and many motors are white. Generally, there are three kinds: brush motor, ZHI－freebrush motor, permanent DAO magnetic synchronous motor and low-end induction motor.
permanent magnet motors (brushless DC, permanent magnet synchronous) are generally used like automatic washing machines. The single-phase capacitor motor is mainly composed of stator, rotor, primary (secondary) winding and end cover.
wave washing machine: single-phase induction motor and DC brushless motor are adopted.
drum washer: single-phase asynchronous two-speed motor (obsolete), series excitation motor, brushless DC motor, three-phase variable frequency motor, etc.
Stirred washing machine: single-phase induction motor (capacitor start and capacitor operation), switched reluctance motor, etc.
