Thread starter sunergeo Start date Sep 22, I have an old washing machine that finally bit the dust, so I've decided to attempt several projects with its remains.

I want to try to make a mechanical chicken plucker using the tub and motor. I've disassembled and salvaged all the useful parts and scrap the grand tour specials, but when it got down to trying to make the motor spin, I quickly got stuck. I'm hoping someone can point me in the right direction. Related General Engineering News on Phys. Baluncore Science Advisor. You may have a multispeed motor with a starter capacitor.

Take a look at this link. Does it help? Hi, Baluncore Yes, I had come across that thread earlier in my research on the net. I followed the suggestions as closely as I could, but my situation's a bit different. I don't have a block on the outside as pictured in the thread, just loose wires. Also, my colors are different. Here's what I've accomplished so far via trial and error:.

As a single phase induction motor it will have at least two windings. They may share a common wire to neutral or each have it's own neutral connection. One of those windings will be connected to active directly, the other winding will be connected to active through the capacitor which provides the necessary phase shift to decide direction.In order to be able to wire the washing machine motor or universal motor we will need a diagram called the washing machine motor wiring diagram ,this one can be used to wire this universal motor on v ac or dc just follow the same diagram.

Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. 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.

Washing machine motor brushes are the left and right carbon brushes the only component in a washing machine motor that can wear down after long periods of time,but can also be used to connect our motor using the diagram in the next step without using a controller,but this procedure should only be unsed to test the universal motor if is working or not,because starting at maximum speed for long periods of time can't be good for any motor. Not all the washing machine motor are the same even if they are universal motor so my advice is to check the connection with a multimeter before doing this technique.

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.

Question 5 months ago. I have a washing machine motor in pieces so that I can check the armature and field coils. I wish to use it in a lawn mower in which the motor has failed. I have identified the wires to the brushes. There are 2 wires going to the back of something at the rear of the motor behind the bearing. All the rest of the wires are white and go to the field coils. Are you able to tell this amateur how to wire this to AC mains volts electricity to run at its top speed?.

I found your diagram confusing because you refer to numbered wires which are not numbered.Where should you look first when your washing machine stops working? While there are numerous parts that could be damaged in your machine, one of the most common issues is a damaged capacitor.

Before replacing your entire motoryou should check this part for problems. Warning: Unplug your washing machine before performing any of these steps.

Use your machine's insulated handles it's equipped with to avoid electric shock. Find the start capacitor, which is the larger of the two capacitors, and remove the metal cover. Discharge the run capacitor by placing one alligator clip from your jumper wire to the housing of the capacitor, and place the other on the metal shaft of your screwdriver. Then, put the blade of the screwdriver to one of the terminals and the shaft of the screwdriver to the other terminal.

This will cause the capacitor to short out, so you don't have to worry about getting shocked from its stored charge. Change your multimeter to the ohm scale. Then, touch the two lead points to one another and switch the adjusting wheel until the needle reaches zero, pointing upward. Touch the leads to the capacitor terminals. The black lead goes on right, and the red lead goes on left. This should make the needle of the multimeter jump from zero to the right before going back to zero.

Finally, reverse the leads. This will make the needle move even farther from zero before going back. If the needle doesn't move, this means that your capacitor is not working, and it should be replaced. We welcome your comments and suggestions. All information is provided "AS IS.

Most electrical problems in air conditioning systems are in the compressors and their relays or motor overload switches. Watch out : live high voltage may be present at a capacitor, capable of giving a tremendous electrical shock even after electrical power has been disconnected at the equipment.

Never work on live electrical equipment. A fractional horsepower electrical motor should show different electrical resistance between the three terminals Start, Run, and Common as we illustrate just below. Electric Motor run speed side note : Incidentally while most electric motors are marked with a data tag indicating the motor run speed in RPMs it's worth noting that the number of run coils is what determines the run speed of the motor.

Two-coils marks a motor that runs at rpm rpm "nominal"while 4 coils marks a rpm motor. Quoting from Part No. SPP-5, a relay and hard start capacitor sold by that company:.

Connect the two wires from the SPP-5 in parallel with the [existing, already installed] run capacitor one wire each side without removing any original wires. Use special "piggy back" terminal of the SPP-5 if all the run capacitor terminals are being used.

Here are some sample capacitor installation instructions for adding a motor starter capacitor to an air conditioning compressor motor - taken from the product package for a relay and start capacitor intended for use on a refrigerator or freezer.

How To Test An Appliance Capacitor With A Multimeter

Similar starter capacitors are available for air conditioning compressors. However there are some other capacitor mounting considerations that can affect capacitor life: basically you want to minimize the capacitor's exposure to vibration and heat.

As Afacp points out, It is advisable to make an experimental measurement of the temperature reached by the capacitor under the working conditions in the final application and after the thermal equilibrium has been achieved.

When testing a compressor, one must discharge the capacitor first! It'll otherwise have enough power stored on it to be at least very painful.

Author and others have been zapped! Some systems will automatically discharge the capacitor, but shorting its leads [to ground] with a screwdriver after verifying that the power's off is a safe way to ensure that you won't get shocked. Motor starting capacitors can hold a charge for days! If oil has leaked out of a capacitor : Don't touch any oil that leaked out: old capacitors may contain PCB oils, an extremely carcinogenic cancer causing material which require special disposal.Washing machine motors can be one of the most problematic components of this household appliance.

After the motor, other common problems can include drainage, electrical, and drum issues. The washer motor is the central unit that drives the entire device. Without it, nothing would work. If there is a problem with your washer, there is a good chance it is sourced in or directly connected to the motor. The reason for this is that the motor provides power to the functioning internal elements of the washing machine. These include the agitator, gearbox, pump, and clutch.

If the motor goes out, everything else will fail to function. The five most common signs of motor issues are listed below. It may happen that the washing machine fails to pump water in and out, as well as spin. This could occur with the motor running, and if it doesn't, it is likely due to a failed lid switch.

This switch is near the door frame, inside the washing machine. If defective, it needs to be replaced. Again, the lid switch could cause the washer to pump water, but not spin. Another possible cause is a broken coupler, the plastic or rubber connector that joins the shaft of the motor to the transmission.

Replacement is the only option when it breaks down.

Washing Machine Motor Wiring Basics

Other possible culprits include a broken belt, a worn clutch, or a malfunctioning drive motor. Drive motors are designed to move in two directions. It can burn out moving in one direction while continuing to work going the other way. Unfortunately, the whole motor needs to be replaced if this fails.

The agitator is designed to move the clothes around in the water before the spin cycle. If the washer doesn't agitate, the problem could be many of the same things: a faulty lid switch, the coupler on the motor, a worn belt or clutch, a failed drive motor or pulley, or the transmission.

If the clutch has gone out, sometimes you will notice a black substance on the ground underneath the washer. This indicates that the clutch needs replacing. After a spin cycle, a washing machine not functioning properly might leave clothes wet.Jump to content.

Concerning the wiring, there are many ways such a motor can be wired. This particular motor is a 2 speed one, and probably wires having the same colour are having the same function.

A lot of washing machine motors have speed sensors, so you don't need the wires attached to that. Then find the wires that are attached to a coil, and measure the resistance. That will give you a little insight in the relative number of windings on that coil, so you can predict which are the high speed coils and which are for low speed.

If you found out which coils are for which speed, you can carefully connect one of the coils in series with a Watt light bulb. This will limit the current in case of a shorted circuit and prevent blowing up fuses. Please note that it is very likely the other coil will produce current when the motor is connected. Also, connect the ground wire first if you don't like being electrocuted. These additional photos might help.

I'm not entirely sure how to interpret this data. It is from the wiring diagram. I get a bit fuzzy when I try to digest it. The red wire goes to a capacitor and I'm pretty sure that's the one I hook up to the hot lead on my 3 prong house plug.Variety of 3 wire washing machine motor wiring diagram.

A wiring diagram is a streamlined conventional pictorial depiction of an electrical circuit. It shows the components of the circuit as simplified forms, and the power as well as signal connections between the gadgets. A wiring diagram typically provides info concerning the family member placement and plan of tools as well as terminals on the devices, to assist in structure or servicing the gadget.

A photographic diagram would reveal extra detail of the physical look, whereas a wiring diagram uses a more symbolic notation to highlight affiliations over physical look. A wiring diagram is typically used to troubleshoot problems and to make certain that all the links have actually been made which every little thing exists.

Click on the image to enlarge, and then save it to your computer by right clicking on the image. A wiring diagram is a kind of schematic which uses abstract pictorial symbols to show all the interconnections of components in a system. Wiring layouts are made up of 2 points: symbols that represent the components in the circuit, and lines that represent the links between them.

Circuitry diagrams primarily reveals the physical position of elements and links in the constructed circuit, however not always in logic order. To check out a wiring diagram, first you need to recognize exactly what fundamental aspects are consisted of in a wiring diagram, and also which pictorial signs are made use of to represent them.

The typical aspects in a wiring diagram are ground, power supply, cord and also link, result devices, buttons, resistors, logic gateway, lights, etc. A line stands for a cord. Cords are made use of to connect the elements together. All factors along the wire equal and also linked. Wires on some areas have to go across each various other, but that does not necessarily indicate that they attach.

A black dot is used to suggest the injunction of two lines. Key lines are stood for by L1, L2, and also so on. Typically various colors are used to distinguish the cords.

There ought to be a legend on the wiring diagram to inform you just what each shade implies. Generally circuits with more than 2 components have 2 standard kinds of links: series and also parallel.

A collection circuit is a circuit where elements are linked along a solitary path, so the existing circulations with one part to obtain to the following one.

In a collection circuit, voltages include up for all parts linked in the circuit, and currents coincide via all elements. In an identical circuit, each tool is directly linked to the power source, so each gadget gets the very same voltage. The current in an identical circuit flows along each identical branch and also re-combines when the branches satisfy again.

A great wiring diagram has to be practically appropriate as well as clear to read. Look after every information. The representation ought to show the right instructions of the favorable as well as unfavorable terminals of each part. Utilize the right icons. Discover the definitions of the basic circuit symbols and also select the proper ones to make use of. Some of the icons have really close look.
