Lionel 2026 Motor???

Lionel AC

Lionel Post War AC motor.  Lubricated and maintained, they are almost indestructible.  I have many of die cast PW engines with the same and even at 65 yr to 70 yr old, they still run great and many can pull more than one would expect, and don't forget the magna-traction!

I don't think Bob's motor assembly has magnetraction.

Thanks guys!  Someone was asking about wiring in a Bluerail bluetooth board.  I thought this would be an AC motor but wanted to make sure.  I suppose it can be done but a rectifier will be needed if he wants to continue using AC from the tracks.

Oh...what amperage are we talking about this motor usually pulling?  That may be the deal breaker on a 2amp board.

I was afraid of that, thanks.

It works on DC too. The E-unit may get magnetized however. It is likely to consistently draw more than 2 amps, particularly with the smoke unit.

Not only that, but to run it on a DC output reverse unit the field & armature have to be shunt wired - in parallel - as opposed to the series wiring for the factory setup. This increases the draw through the reversing circuit by a factor of two to four depending on how you execute the scheme.

Rob, why would you run it as a shunt wound motor with the armature and field is parallel?  I would think that there was way too little resistance in the field coil to do this.

Not so. This is a series wound universal motor. As is, it will run on AC or DC. To reverse this motor, you have to change the RELATIONSHIP between the armature and the field. One way to do that with DC is to put a bridge rectifier on the field. That way, the field is always the same polarity and the motor will reverse as you reverse polarity to the armature-field combination.

That will turn it into a DC motor and it will no longer be able to run on AC.

But the armature and field must always be in series with each other. If you put them in parallel, you will burn out the field and the motor will develop almost no power.

You are both correct, I misstated the correct way to reverse a universal motor with DC - the current draw is way too much... I use a bridge rectifier to power the field(or armature) and wire it in series with the armature(or field) to reverse it using DC. The results... it works but not that well as far as power, speed, torque, current draw. They just run better series wired/wound.

You could just leave the mechanism alone and the engine would work fine on DC with reversing provided by the e-unit.
