Almost no resistance unmoving the rotor from horizontal to vertical. no, I don’t have iron dust. Where would I get some?

Switching polarity through the contacts has no discernible effect. The magnets will vibrate slightly and the motor will get hot. That’s it.

Were there any other major differences between my motor and your motor?

Yes, I do. Thanks. That explains what my motor has been doing. I'll make the changes. Thanks for walking me through that.

Thanks! The picture helps. My commutator “cuts” are aligned with the coils. If I understand correctly, my commutator needs to be rotated so that they can operate in the manner above. I think the commutator halves need to be smaller as well Sorry about this. This is all kind of new to me...

thanks for the advice. I’m using copper wire for the contacts, and have them touching the commutator at 180 degrees apart.

I wanted to use ball bearings, but couldn’t really find any locally, and shipping for most of these parts takes upwards of two weeks to reach my location. I think I understand what your saying about the commutator, I’ll look at it and see what I can do.

I knew that the 21,000 rpm was unrealistic, I was just looking for something that moved fast.

Yep, USA. I’ll go to Lowe’s and see if they have those, thanks.

Also, shaft is a carbon fiber rod.

Thanks for your response. 1) the nuts aren’t bearings, they are glued to the shaft to prevent it from moving side to side. 2) the bolts I have currently are magnetic, but very weakly. 3) I have verified that the magnet poles are correct (north on one side, south on the other) 4) how should...

Posted at almost the exact same time. Oops. Lowe’s is my main supplier, but Home Depot and Ace Hardware are also options

I looked into it and the A2 signifies 304, while 70 is related to the hardness. What number is recommended?

Here’s the bag it came out of

The head of the bolt says A2-70 and “THE”. What number bolt is the best?
