Wasabi Posted August 10, 2015 Report Share Posted August 10, 2015 For a while I have thought my magnet has been running too slow. When comparing it to a friends this was confirmed. His does about 40 Rpm and mine about 28. I thought my battery had had it so tried a new one but it's the same. Any ideas how to speed it up? I don't use a speed controller on it.

Redditch Posted August 10, 2015 Report Share Posted August 10, 2015 Almost certainly rust. I posted a discussion about this a couple of months back. Take the motor / gearbox unit OFF the frame, then remove the back plate off the gearbox, then remove the circlip at the front from the shaft, and knock the shaft out of the gearbox (towards the back) with the main gear. You will find the shaft and its housing are fully rust (almost certainly, as their is no seal, and being vertical water gets in, and sits there when you pack up) Now get some emery cloth or a wire brush, and remove all the rust from the shaft. Get some emery cloth on the handle of a tooth brush, or on some wooden Downing, and clean the rust out of the shaft housing. Next spray a little WD40 or diesel into the shaft, and push some kitchen roll through it to remove the bits of rust left. NOW, pack the shaft housing, and cover the shaft with some heavy duty GREASE. Pushe the shaft back in aligning the gear in the gearbox, and replace the circlip on the shaft. Next PACK the gearbox with extra grease,and replace the rear cover. Now replace into the frame and switch on, and that should have cured the problem. IF it doesn't cure the problem, then you just have a slow motor / gearbox unit (some do use slower ones, ideal for crow, but not for pigeon), and the only cure then, is just use it for crow, or get a faster motor / gearbox for it. Use a speed controllerUsing a speed controller on a slow motor/gearbox unit won't make it faster, will only facilitate making it slower.Also, if he has rust in the motor/gearbox unit, the extra power drawn trying to overcome the friction of the rust, would cause the speed controller to burn out.

Cosd Posted August 10, 2015 Report Share Posted August 10, 2015 (edited) A speed controller will not speed up a magnet, it can only slow it down. If its the usual window wiper motor type magnet, check to see if there are a number of spade connectors, these (usually) control two speeds for the magnet. You can try moving the wires to see if that helps. If you get stuck, see if you can post a picture of the connectors.

malkiserow Posted August 10, 2015 Report Share Posted August 10, 2015 your battery may be failing? Try your mates battery on your magnet and see what happens. Quote Link to comment Share on other sites More sharing options...
Redditch Posted August 10, 2015 Report Share Posted August 10, 2015 your battery may be failing? Try your mates battery on your magnet and see what happens. He tried a new battery, no difference in speed Quote Link to comment Share on other sites More sharing options...
Wasabi Posted August 10, 2015 Author Report Share Posted August 10, 2015 Thanks all. I've stripped the motor and gears and found no rust. I'm going to see if I can find the different spade connectors. Quote Link to comment Share on other sites More sharing options...

JDog Posted August 10, 2015 Report Share Posted August 10, 2015 What is wrong with 28 rpm? It is movement that counts. Quote Link to comment Share on other sites More sharing options...

motty Posted August 10, 2015 Report Share Posted August 10, 2015 What is wrong with 28 rpm? It is movement that counts. I would say that 28rpm is adequate. Quote Link to comment Share on other sites More sharing options...
Wasabi Posted August 11, 2015 Author Report Share Posted August 11, 2015 I've always thought a bit faster was better. Maybe not. Quote Link to comment Share on other sites More sharing options...
Greenhunter Posted August 11, 2015 Report Share Posted August 11, 2015 Have you got a long connection to/from the battery? That can slow a motor down due to the extra length creating more resistance. I think mine runs fairly slow, still seems to work. GH Quote Link to comment Share on other sites More sharing options...
Wasabi Posted August 11, 2015 Author Report Share Posted August 11, 2015 Right then! I took the motor to bits last night and the bearing at the bottom of the housing was dry and making a right noise. I greased it and put it all back together. I then used it today and it is going faster and shot 55 on a rape stubble! When packing up the electric motor housing was very hot. Is that normal? Never noticed it before. Quote Link to comment Share on other sites More sharing options...

Depends on the motor, but if it's been a hot day, and the motor has been running fast a few hours I would expect it to be quite warm, although not hot enough to burn you Quote Link to comment Share on other sites More sharing options...
pigeon controller Posted August 16, 2015 Report Share Posted August 16, 2015 Mine was running slow last year and I found the wire at the spade was fraying , reconnected and soldered and it was good as new. Quote Link to comment Share on other sites More sharing options...
ditchman Posted August 16, 2015 Report Share Posted August 16, 2015 several of you may have seen my attempt of making a geared magnet................well i have almost finished it now...it is running at 40rpm and an 8.6" diameter swing which will give it a decent perifery speed...i have aluminuin pigeons cutouts on it painted by the famous artist....(moi)....and i will be giving it its first outing this coming week....being a manual flapper man...i datesay i will be asking for a few pointers from you magnet men.............
