Hey guys. a followup video is now online! Learn more about the motors:

[Petertronic]

Nice teardown! My 1999 Bosch machine has a similar Siemens motor, in fact the drum and a lot of the other parts look the same. I changed the brushes in 2014 and it is still running perfectly!

I once built a knife/axe sharpener from a setup like this. Took the motor and drum assembly from a 1970 top loaded drum style washing machine and a big (about 50cmx10cm) grinding wheel. Moving slowly with a small water reservoir at the bottom. Works great!

Sorry if I sounded tired and possibly "uninspired" at the end of the video, I had to keep down my voice because it's already technically Monday morning here and I didn't want to keep the neighbors awake with my loud voice. I had to whisper into the microphone. I'm commenting on it because I'm actually quied excited about building some of the stuff that I mentioned at the end of the video, now that I have the new shop and all.
Have a nice rest of the weekend,
Gerolf

I liked the lab supply power build, please don't stop making some of the more technically advanced videos. It's why many of us love your channel

I have been playing with the idea of building an electric vehicle for a while now. I did not have the technical knowledge yet, working with motors, controlling them, working with metal, etc. Your videos are the best resources I have found so far to get new ideas and also as a source of information and learning what I need to learn to build the vehicle. I have been putting together some tools and collecting parts from the street (I live near Hamburg). It seems that completing the project might take me around 3 years at least but I'm very excited about it. Thank you for the invaluable videos!

That three pronged casting is called a spider, used to disassemble hundreds of them every day due to a bad batch of faulty bearings in Hotpoint model, they had edge bolts that needed drilling out and then u had to pry bar it away from the drum, the hotpoint ones have a plastic outer drum made in two halves with a seal. What a back breaking job that was!

[maxwang]

I like the way you salvaged the drum shaft as an intact part.

[oldman]

That inner drum with all the holes is good for camping for your camp fire. I had one sitting in my fire pit at a state park with a fire going one time. The wind came up quite strong and the park rangers were ordering every one to put out there campfires I was ok. I had placed a metal trash can lid that I had drilled 1/2 inch holes inon top of it and had coffee purking in the coffee pot. The head park ranger liked my set up. I did not have to put out my campfire because it was safely controlled.

so cool to see you are back to working on washing mashine motors again! would love to see applications for those.

[Seegalgalguntijak]

The door of this washing machine makes a great dish, not only for salad, you could even make a casserole in it because it is really thick and heat resistant glass, so you can easily put it into the oven without damaging it.

[LydellAaron]

Absolutely love your videos and the logic paths that you take. There are many discarded washing machines out there, so using their motors is a great idea. Thank you!

[joelaut]

Nice breakdown of a scrapped machine, thanks!

[matschase]

Don't know why I'm excited for washing machine motor videos, but I am. Already collected one

[andrewwilson]

The drum makes a very good garden burner. Sit it on a ring of bricks and it makes a really effective fire pit for chilly autumn evenings. A few bits of scrap wood provides hours of nice free heat.

If you can independently control the stator and field windings, you could turn this into a regulated AC output alternator. I realize that the EU uses 240 VAC @ 50 Hz but by varying / regulating the voltage to the field / rotor windings, you could get a stable voltage from it. Maybe use a battery and charger circuit. Some people use capacitors to energize field windings but I don't know how stable this would be. If it sets for a while and the capacitors discharge, you'd need a voltage source to get it started anyway so you may as well go for batteries and avoid the extra parts. This would make a good project for a water wheel driven alternator too. I saw a video years ago where a guy in New Zealand used the tub and motor from a front loader that had the newer permanent magnet motor. He cut flaps in the tub to catch down hill flowing water to turn the tub and motor. The holes in the tub kept it from filling with water through the cut flaps. He funneled the water into a pipe with a valve in it. He took the handle off the valve. He then direct wired a home made control circuit to the motor of a battery powered electric drill. He mounted the drill body to the apparatus away from the water and then he put the shaft of the valve in the drill's chuck. If the water flow was such that the alternator put out 240 VAC, the drill's control circuit was in balance and the drill did nothing. If the water began to flow too fast and the voltage increased, the control circuit would be out of balance and input a forward voltage into the drill's motor and it turned the valve partly closed to slow the flow of water. If the water slowed and the voltage dropped, the control circuit went out of balance again and input a reverse voltage into the drill's motor to open the valve to bring the voltage back up to 240 VAC and bring the controller back into balance. It showed the drill in action as he affected the water flow with his hand. It was really ingenious. I wish I could say that I invented it but that would be lying.

You could build a metal cutting bandsaw with that transmission and motor!

About 10 years ago I bought a new washing machine and about 5 years later it started leaking (out of warranty). It is a top loading high efficiency washer and I was able to obtain a new drive shaft and seal kit. I was surprised that the machine used a very large brushless motor (about 300mm diameter) with the rotor (with magnets) directly mounted to the drive shaft. The stator coils were mounted to machine. This means no transmission or belt reduction at all. To reuse this type of motor would be more difficult as the motor is really part of machine frame so one would need to cut the frame down to just save the needed parts or to fabricate a new frame for the motor. This would be interesting to try and use in a project though.

A cargo trike would be a perfect match because in the center jackshaft you could connect the motor's reduced speed shaft assembly to it via bike chain. It'd be about pedal speed. Might be a little low in overall power but if you only wanted to do 10mph it'd work fine.

You could use the motor plus a heating device to make your own industry sized (simplified) Thermomix. Could be useful for partys, when you make like ten litres of Chili con Carne with it. It would require a programmable input method though, similiar to that of a microwave. Basic functions would be Spinning speed, Temperature, duration of spinning, duration of heating, intervals, Go, Stop, Pause, Reset.
