Washing Machine Motor Speed Control Circuit

How to speed control washing machine motor with a simple circuit

Clothes washer technology developed as a way to reduce the manual
labor spent, providing an open basin or sealed container with paddles or fingers to automatically agitate the clothing. The earliest machines were hand-operated and constructed from wood, while later machines made of metal permitted a fire to burn below the washtub, keeping the water warm throughout the day's washing.

The earliest special-purpose mechanical washing device was the washboard, invented in 1797 by Nathaniel Briggs of New Hampshire.

By the mid-1850s steam-driven commercial laundry machinery were on sale in the UK and US. Technological advances in machinery for commercial and institutional washers proceeded faster than domestic washer design for several decades, especially in the UK. In the United States there was more emphasis on developing machines for washing at home, though machines for commercial laundry services were widely used in the late 19th and early 20th centuries. The rotary washing machine was patented by Hamilton Smith in 1858.[3] As electricity was not commonly available until at least 1930, some early washing machines were operated by a low-speed, single-cylinder hit-and-miss gasoline engine.

Step 1: Universal Motor

The universal motor is so named because it is a type of electric motor that can operate on 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. Hence the resulting mechanical force will occur in a consistent direction of rotation, independent of the direction of applied voltage, but determined by the commutator and polarity of the field coils.

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.

Step 2: Washing Machine Motor Uses

If you want to check my youtube channel

https://www.youtube.com/channel/UCPjqH3HfNA4Shttkx...

there i have some videos related to the washing machine motor things that i have discovered, tests trial and error but that is the way we learn best.For the today tutorial, i will show how to control the speed of your washing machine and you can use it after for your project i saw people making disk sander, belt sander, wood splitter, propellers, go kart, electric bike from this motor so it's very useful cheap and reliable.

Now you can do it more complicated with the taho wires and some kind of controller maybe Arduino based

but i will show an easy manual way to control the speed of the washing machine motor....

Step 3: Voltage Controller and Light Dimmer

First is a dedicated ac voltage motor controller

that you can find online and is made just for that to lower the voltage of the mains according to the pot minimum is 50v this method is very easy the device has input terminals and output.In the input, you connect the main lines and output your washing machine motor or another load.

The second method is to use a regular house light dimmer

Dimmers are devices used to lower the brightness of a light.
By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). More specialized equipment is needed to dim fluorescent, mercury vapor, solid state and another arc lighting.

Dimmers range in size from small units the size of a light switch used for domestic lighting to high power units used in large theatre or architectural lighting installations. Small domestic dimmers are generally directly controlled, although remote control systems (such as X10) are available. Modern professional dimmers are generally controlled by a digital control system like DMX or DALI. In newer systems, these protocols are often used in conjunction with ethernet.

In the professional lighting industry, changes in intensity are called "fades" and can be "fade up" or "fade down". Dimmers with direct manual control had a limit on the speed they could be varied at but this issue has been largely eliminated with modern digital units (although very fast changes in brightness may still be avoided for other reasons like lamp life).
