This electric motor is called a universal motor. The universal motor is a type of electric motor that can operate on either AC or DC power. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator.
It is often referred to as an AC series motor. The universal motor is very similar to a DC series motor in construction but is modified slightly to allow the motor to operate properly on AC power. This type of electric motor can operate well on AC because the current in both the field coils and the armature (and the resultant magnetic fields) will alternate (reverse polarity) synchronously with the supply.
Tach Coil is an essential port of Washer Motor . In the back side of the motor, you can find the tach coil with we will not use but is good to know if you need to replace it with spare parts if this one is gonna break. By the name, I am guessing that with this component the washing machine controller is sensing the rpm of the motor and it regulates the speed according to the faze of the program.
washing Machine Motor Specs is also of great importance. Universal motors have high starting torque, can run at high speed, and are lightweight and compact. They are commonly used in portable power tools and equipment, as well as many household appliances. They're also relatively easy to control, electromechanically using tapped coils, or electronically. However, the commutator has brushes that wear, so they are much less often used for equipment that is in continuous use. In addition, partly because of the commutator, universal motors are typically very noisy, both acoustically and electromagnetically.
