LGB Point Motors

I have several LGB point motors (No 1201) does anybody have any idea how many amps these things draw? Can I take it voltage is a bit variable, i.e. anything between 12v and 18v ish?
 
Not sure of the current draw as it's only momentary, but 12-18 V ac should work fine.

I run mine off an LGB 1/2 A controller with no problems and I can change 2 motors together on crossovers....
 
Cheers Gizz. Reason I was asking was the rating for the switches.
 
The current draw isn't much on these, but it does depend on the condition of the point and motor, and I think there is a relation to the voltage you are using. To be honest it can't be anything more than 1/4 amp. I tried measuring it but I'm using a cdu and the pulse is too short to read on my meter! For quite a long time I was using the sub miniture toggle switches from maplin, they handled everything fine, well before I started using a cdu.
 
I have now acquired suitable switches, but another thought occured. Has anyone tried to operate two sets of points, such as a crossover, with just one motor, there would appear to be plenty of power? Daft thought really as I do have sufficient motors (just) to do the job, but perhaps an interesting exercise.
 
These things barly have enough Oooph to power one switch at times let alone throwing two sets of points!!
 
I stuck 18v across the several that I have and the damned things near jumped out my hand, I'm amazed you think they're gutless. I am using Peco points which only require 1oz (sorry, imp. measure AGAIN. Cant help it!:bigsmile:) to move them over. I also have two that are 'trailed' and operate each other through a simple linkage.

I didn't say they were gutless.............just wait till there not brand new anymore and they've been outside for a few month's!! they are solenoids not motors so the torque is applied very quickly and for a very short period, if it don't go fully over in the 1st burst it ain't going to go over. If it gets the wrong sort of supply ie. continuous current it will burn out in very short order. And I use 24v 5amp supplys for my EPL system and still have the occasional missfire..............................
 
I have found a capacitor discharge unit gives the motors a little more oooomph, just use a reversing dpdt switch to operate the point, plus no worry of burn out.
 
The ones that I have are small electric motors and not solenoids.

I think that you will find that they could move two points simultaneously some of the time but not all of the time as they do tend to misfire occasionally.

Why not try it and see. You have nothing to lose.
 
Aboslutely!.
