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

Grrrr the sly buggers :-)

oh well

Thanks anyway John

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

kim :o)

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:

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. Keith

Make friends in the hobby. Visit Garratt photos for the big steam lovers.

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:-
