Title: Faster in reverse?
Post by: dragonbusa on June 03, 2017, 01:08:55 PM
Why would my locomotive's have more power in reverse? Now I'm very new to this hobby so my knowledge is very limited. I been into slot cars for years so I know the little motors work, I'm thinking maybe the brushes are worn in one direction and when you go in reverse they make better contact?

No I think it has more to do with the gears then the motor.  What locomotive is it?

Reverse is accomplished by polarity not by any gear change. there is no transmission to make a gear change its all direct drive is it not?

It has always been a weird quirk in model railroading that locos seem to run better in reverse. This has been discussed ad nauseam in years past. Dunno why this is so, but it always seems to be true.

I know the locomotive does not have a transmission, but it has gears.  You can have more friction one direction than you do in the other.  If you have more friction it is going to cause it to run slower.

Gets me to thinking .... pull the motor out and in stall it backwards then see what happens LOL!
