Goedendag ;-) To be honest, the company is not Italian but Swiss. However they have an Italian page for ordering magnets and with lots of background...
Hi, I`m building an underwater ROV and I`m considering using outrunner motors; I was thinking I can seal them from the water easier than a standard motor. ...
Hello Everyone I am designing a small 2.5 kg UAV as a student project. I am basically a flight mechanics and aerodynamics guy and am caught up at the selection...
Hi Vineet To made the right choise you need to take a flight profile. It can be flight under continius power or intermittend power and glideflight. What`s the...
Goedendag ;-) A Ralph Okon project, 67.5 *25mm stator from a printer, 100/150Ampère: <http://www.rclineforum.de/forum/thread.php?threadid=132126> Vriendelijke...
Goedendag ;-) The guys (i.e. Ralph Okon) in the powercroco subforum at <http://www.rclineforum.de/forum/board.php?boardid=89> are running a group order for...
The maxiumum working temperature of N52 is 80 dgree centigrade,if you want higher temperature,you should choose M ,H,SH,UH,EH,AH series,anybody need magnets...
Aloha. Thanks for the info about the Dr. Ralph magnet group order. I am having difficulty breaking through the language barrier at this time. Would some one ...
I seek advice/knowlede-input for my project. I plan to mount an outrunner such that *both* the coils and the magnets can rotate (in opposite directions)....
Goedendag Jimbo, Sorry, I should have translated it in my first message: " ... 10er segmentmagneten mit 18° teilungswinkel für 100% abdeckung und 1,85mm...
Hello Christopher Maybe you could also use 3 rotating rings+brushes for A, B, C phases and keep the ESC outside. Louis ... De : drakecn <christopher@...>...
Hi Jimbo, How do you do! I'm a Neodymium-Iron-Boron-Magnets manufacturer in CHINA,I'm glad to offer you if you could send me the drawings and quantities,we...
Hi, I get what you mean but there will be nasty losses using brushes and you will need to transmit the signals to the speed controllers. Now you have not...
Hi Guys, Would it be possible/ practical/efficient to rewind a Plettenberg Predator 10-15kw Motors so it runs much slower eg around 2700-3500 rpm for direct...
it`s long ago I tested this setup with one lil`CDR stator. the power goes thru brushes out of an old 480er brushy. It works in my 220gr BUGATTI R101, but I had...
Hi William BTW if you are in China .. Do you know a small low-cost LCD gaussmeter ? Or a gaussmeter probe for a DMM ? It could interest a lot of DIY outrunner...
Hi louis,I sorry,I don't know much about gaussmeter,we have some gaussmeters in the workshop for inspection the magnets,but don't make gaussmeter. William ... ...
... Hello Louis, There has been a few articles around about making a gauss meter probe using the hall effect sensors from a CD ROM drive. They are not...
... I think your biggest problem would be that with nothing to force the inner and outer to rotate at the same speed then they wouldn't. IE your inner could...
Goedendag, More free 'magnetic' simulation software, Maxwell SV, a subset of Ansofts Maxwell 2D software. I have no experiance with this software or with FEMM:...
Goedendag Mark, Not from experience but I guess that rewinding the Predator would be no problem. You know its original Kv and number of winds (count when...
Looks suspiciously like litz wire from these photos so should be easy to remove the wire even if epoxied in. If the wire is glued then you may damage the...
Another thought. Do we know if it is wound star or delta now? If delta it would be easier to change that to star than to rewind. This would increase torque by...
