Home made electric motor.

Always wanted to put together a electric motor, armature is from a drill magnets are earth magnets.

Runs smooth!
Now for the real question, what are you going to use it for? Have you thought about a rheost so you can dial it down?

Thanks Gunny, just wanted to see if i could make one.
Just ordered a DC dimmer

SWEET! I remember helping one of my boys build a DC motor for a science project. He even wrapped his own armature. At that time I was working for an outfit that made tiny electric motors, I mean the size of a small pecan. Mostly for the military but one automated line was for a slightly larger motor for a hair dryer. After the armature segments were pressed onto the shaft, it was powder coated in a fluidizing bed. A real human placed the armature into an automatic winder.

Thanks Ron, i may try winding the coils on another one.

you need to write a book named "Pitchy's projects" which shows all of your genius ideas. Mind you, it will probably be a volume edition!

Thanks buddy.

I remember when I was in the first grade we had shop class.Our first project was a pot holder hanger cut out with a coping saw. Those with more aptitude finished that and went on to hand wind armatures and build a small DC motor. I wasn't one of those.

In Grade school, we built a small battery operated motor for science class. Most of the class put the little strips of copper used as brushes on too tight and it wouldn't run. Mine ran pretty well. It was fun.

That's mighty sweet, bro! Seems like it could do some honest work, too. Could you slow/gear it down enough to run a small ice cream maker?

[Pitchy]

We`re building one of these, my question is why do they have the spinning winding so low beside the field windings.
When i put power to the field winding's the strongest magnetic pull is up on the side of shaft.
I think i`m going to put the spinning part up higher beside the shaft the winding's are on.

Cool, Lenn!
When I was in 5th grade, I made one for the science fair. Nowhere near as nice as yours, though.

[Pitchy]

Thanks Jay, i`ll build this one the way i think it`ll work so it probably won`t

[OldWin]

Haha well I'm bettin' it will!

[marlinman93]

Does it start on it's own when you put power to it, or do you have to give it some help to start? Magnets seem a bit far away from the armature. How did you determine that spacing?

[Pitchy]

Here`s what i have thus far, i just figured out that the armature has to be insulated from the shaft it spins on or it will be magnetized from the base.
So will have to drill a bigger hole in it and make a wood bushing.

[Pitchy]

It`s a no go on the , motor not electrical smart enough to figure it out.
Got the upright coils magnetized and the contacts on the rotor are working, oh well it looks nice.

[Pitchy]

Persistence pards, took us four days of aggravation to get it running, made a new three pole armature.

Hey! I knew you could do it. Simply amazing. Gotta be satisfaction in that.

[Pitchy]

Thanks Ron, it still isn`t quite right the armature heats up so can`t run it long.
I`m no electric wizard by far, was lucky to get it to run.

[Pitchy]

Finished motor.

Cool! Looks really nice, Lenn. Electrical is definitely my weak spot. I couldn't have built that haha.

[piller]

The only easy part about electricity to me is that it needs someplace to go and that someplace can be a human if there is no other pathway. As far as making the right pathways and the right amount to do what I want it to do, that is more difficult.

Pitchy, you are better than I am at making an electric motor.

[Pitchy]

Thanks Jay and piller, like i`ve said gotta try everything once.

[Bill in Oregon]

Lenn, wouldn't that make a nice powerplant for a big tin ship?

[Pitchy]

Thanks Bill, i take it ya mean the first model the second one is pretty tall and don`t have much power.
