Hello
Does anyone know if it is possible to fit the 5 pole armature from their
ringfield motor straight into the older 3 pole ringfield motors
Thanks

It's not possible, they have different armature shaft diameters.

You would think someone would have invented a brushless DC motor by now?

Why don't you set to work and invent one? After you've perfected your
perpetual motion machine, squared the circle and duplicated the cube of
course.

Like this perhaps:

this type of motor has existed for many years.

It's called a linear motor.

No its not.
Linear motors are a different thing entirely and could be built with
brushes although most are AC and don't need brushes any more than
rotary AC motors do.

The problem with DC brushless motors is Torque, unless you have large
windings and rotors they do not produce much torque.
Sony developed Tiny brushless dc motors for there top of the range walkmans in late 80s and early 90s but these would not produce enough torque to be useful in a loco.
That's my two penneth worth

Dc Brushless motors have been around since the very late 1960s in the hi-fi
turntable world but the problem with them is they do not produce enough
Torque unless you have large windings and rotors and associated circuitry to
drive them.

Sorry, missed your follow up. Just changed my newsreader characteristics
and it surfaced. Look at:-
