Hello all,

I'm in the final steps of finishing my ip engineering Shelly tram but I am having great difficulty with the motor unit/deluxe chassis. I am competent with quartering the wheels so thats not the issue but the motor is giving off little power and torque and stops very easily when gently touched with my finger so it will have no chance on the track! I've moved the motor mount as the screw holes are elongated to allow the gears to be adjusted to give a smooth run but I'm having a lot of difficulty in getting this right.

Has anyone lose built this tram or a deluxe chassis and can give me some pointers as I'm stumped! I've build kits before, live steam and battery but this has got me baffled! Also, I can't adjust the gears for very long as the motor is getting very hot (overheating?) where I can't hold it in my hands.

Any tips or assistance is greatly appreciated.

Regards

Daniel
 
Sounds like the motor's duff not your assembly. I had this on a Bachmann loco and it only lasted 5 mins before it burnt out, turned out to be a batch of dodgy motors as a friend at bachmann said they had a load back for repair which they did at no cost. Take the motor out and run it on its own and see if the same happens, if so give Ivan a bell and I'm sure he would exchange it. You should be able to get a free rolling chassis without the motor in.
 
I've no direct experience with the Deluxe chassis but the motor gearbox unit and mounting looks identical to the one on the IP Jessie which I built. I had difficulty getting the gears to align in the whitemetal casting - all too easy to get glue in the wrong place resulting in binding. I got through three gearboxes before eventually replacing them with a USAt motor block. See - http://riksrailway.blogspot.co.uk/2014/04/how-i-improved-mechanism-for-my-ip.html

Don't know if you've made any progress here.

I'm not a fan of IP's mechanical kit, I think it's Summerlands Chuffers or Swift Sixteen who are offering a Mabuchi 385 motor for about £6.50 that'd doe the job :D

Just a thought. Quite a few motor ranges (e.g Mabuchi) use the same "can" to house armature windings to suit different voltage ranges. Could be yours is designed for, say, a 3v power source rather than the 12-18v you might be using if track powered. Especially as you say it seems to have the inability to pull the skin of a rice pudding.

I remember from my slot car racing days, some 45 years ago, you could have some very small motors that were "wound" to propel a weighty car at a real (not scale) speed of 70 mph. And for quite some time. Max
