The type of stepper motor in the last video looks pretty powerful Jonathon - don't know about UK but they are pretty expensive here.

Looks just like the type and size that drives our Laser - very expensive item to replace . Should imagine its cheaper to buy a conventional outrunner unless you happen to have a couple of those lying around ........

Wonder what amps it draws and what voltage.

The jumble of wires that you can often see are akin to an ESC

This video is interesting as it shows the slow & smooth movement as well as significant rpm

Wonderful links Liked the music.

A few YouTube links to while away some time...

Thanks redpmg that helps a lot.

Not foolish at all Rick - mainly used in CNC machines and modern printers, computers etc. They only move a certain measured amount backwards & forwards to allow precision placement for printing or cutting/engraving. routing, milling and other CNC machining. Computer controlled & all done by built in hardware & software in the particular piece of equipment being used - in our case a Laser. The movement on our particular machine is accurate to .1 of a millimetre which allows multiple cuts .

As was said a stepper motor is basically a brushless motor and it works in the same way . Just how it does is beyond me............. Had it explained once - never understood.
They look very different however from what we know as brushless motors - will dig mine out and post pictures later.

Is it foolish to ask what a stepper motor is or how it works.
Rick

What an interesting thought - you may be onto something - essentially they are just brushless motors.

Some of them have significant torque - you have got me think now as I am looking for 2 motors for my 8ft HMS Hermes...cogs are turning in my head....

Let me mull that over and I will come back to you with a considered response rather than shooting from the hip....

Quick couple of questions - could you use stepper motors to drive a boat ? & how would you do so ? and finally how can you tell what voltage to use ?

Salvaged a whole lot from scrapped printers but apart from the gears don't seem to have much use for them at the moment . Electronics are beyond me ...............

Could not find these earlier... hopefully self explanatory

Nice to find yet another buddy on here 🤗

Hi Jonathan,
Sorry i forgot you were working on Rodney's guns.

They are coming along nicely.
Better each time i see them.
Keep up the good work.

Hi Martin,

This will be used on HMS Rodney

Hi Jonathan,

Is this itching a scratch you had or is there a project that we can look forward to.
