Well that sucks, I paid about $60 for that if my memory serves me right
The motor does absolutely nothing so i'm assuming it's deaded.
Nope, but it needs a specific size and shape. Power source can probably be adapted by use of resistors, speed is only relevant in terms of how far it travels before being reset by the spring. It'd work just as well IMO without needing the spring at all.Does it have to be that specific motor?
You checked across the lugs on the motor for continuity btw?
And like a Phoenix from the flames the motor appears to now be working. It's aliiiiive!!! It's aliiiiive!!!
Strangely the continuity test on my multimeter still doesn't get a reading across the motor connector. I'm assuming it needs the resistance to be below a specific level for the tone to sound and maybe the resistance of the wire used for the motor windings isn't low enough. Sure enough if I drop the multimeter to normal resistance measuring mode I get a reading which suggests continuity IS there.
The motor wasn't working at first but I got a small screwdriver and gently lifted the black plastic cover on the back. I couldn't quite work out how it fitted in place so I gently kept lifting it and eventually the whole thing came off in one piece. Like this.
Now before I removed the cover the shaft of the motor didn't seem to want to budge one bit. But the minute this part was taken off it moved much more freely. I hooked it up to the power source and went into the coil test and sure enough when I fired the relay for the saw motor it moved. Hurrah for that!!
I then put the cover back in place and tested again and it still worked. It looks very much like the motor had siezed up a little (not really surprising - i've no idea when Dan got it but i'm guessing it was a while ago). I've tested it numerous times since and every time it's worked. It doesn't move especially quick but I think it's only meant to go at around 3rpm so it's doing what it's expected to do.
Brilliant news. Here's a video of the saw motor in action.
Next up I need to get a proper connector fitted to the motor. Can anyone tell me what this type of connector is called and where I might be able to get one? Also if someone could advise on the pin type and tool i'd need to fit them then that would also be extremely helpful.
Once i've got the motor hooked up then I still need to do a couple more jobs. Firstly I need to get a 2" meccano pulley as the 1.5" one that i've got is a little too small hence why the belt is slack. I've located a place that sells them here: http://www.meccanospares.com/shop/article_20a-BL-N/2"-Pulley-Blue.html?sessid=IkyymQomcoVctgKMdpqIt50yTC3RtNRoAp9ceT4NhE9xqSmVjIOobzHcYxHaIPuF&shop_param=cid=30&aid=20a-BL-N&
And then the final missing component is that darned torsion spring. I've found a place on eBay which will sell me a bag of 100 assorted springs for a few pounds so I reckon i'll end up grabbing that and then having a bit of an experiment to see which gives the required tension.
