How to Make an Electric Motor at Home

Might have a go at building something like this

my electric heater has a fan motor that is starting to get noisy, ball bearing ?

My electric fan heater got noisy then quit, so I took the motor apart. The motor itself showed extreme signs of wear, not just erosion of metal but the metal had flowed quite a distance, enough to bridge the electrical gap. I compared the motor with that of an air conditioner that had stopped working and they were identical apart from size except – the air conditioner motor showed no signs of wear. I concluded that the fan heater was designed to fail – planned obsolescence. Checking web, I don’t see that motor design in a google search for images, but sort of like this.

A high school project for miss m was to build a working electric motor. It was extremely difficult. I helped and we eventually got there but she still got poor marks. Brushes and frictionless bearings are not the sort of thing that it is easy to make at home.

Electric motor in video looks pretty. Uses a heck of a lot of epoxy putty.

The only school child to get a good mark for this assignment made his electric motor from Lego.

I suspect that you might like watching the occasional BOLTR (Bored Of Lame Tool Reviews) video then. It’s a very skilled Canadian chap who has a huge following, and with the money he receives from Youtube and Patreon to buy various tools, then completely dismantle them, and fully examine how they work, etc.

An example

Every year joe buys a ten dollar appliance , the government takes 1 dollar in tax

If the appliance lasts ten years the gov makes 1 dollar

If the appliance lasts 1 years in ten years the gov makes 10 dollars

This is why the gov likes planned obsolescence

You never know how long a tool will last until it wears out.

Hey, Bill, thanks for the link to that site. I enjoyed the video and will be watching more.

Well, you do actually if you choose carefully, use carefully and service it yourself.

Using Lego is cheating, and that motor looks really good.

i reckon frictionless bearings would be hard for anyone to make.
