DIY motor tools and parts sources


Since this is the first post on this forum I think it would be very helpful to have a list of tools and source for DIY motors.


All parts you need for your DIY project

www.gobrushless.com
www.strongrcmotors.com
www.komodohobby.com


CD motor Performace database - Very helpful to have a good idea about what to expect from your project

Rotor Calculator - If you don't know which magnets will fit on your project check this out.

Statorpoles / magentic poles / winding scheme table - Chart about tested and best motor build combinations.

The master Ralph - For projects bigger than a CD motor always thinking of efficiency this is the website to visit, awesome tutorials, tips and data. Can be translated using http://babelfish.altavista.com

Lens RC - DIY motor KITS and a great tutorial on how to put everything together.

Mini lathe comparison chart - Getting serious about turning your own parts but you don't have a lathe? this chart might help taking the decision.

Magnets for all projects - No matter what size motor for your RC plane you are building, George has it.

http://groups.yahoo.com/group/lrk-to...=1&viscount=50 - Info about steel for self made motor parts.

Feel free to post more links with helpful information and keep this thread ONLY for this info.

LRK has a lot of motor design info


This page is a little out of date now, but there is a lot of great information about self-made motors.

Very nice CNC cans for the 'standard' 22.7mm (single, double and triple) stators, plus most of the usual bits and pieces.

A low tech suggestion, a bamboo BBQ skewer for packing the winds onto the stator.

DVD on motor Building and testing


bkahuna's DVD on Motor Building and Testing . Features Kits from Strong RC Motors and Custom CDR. It covers magnet placing and gluing, winding techniques, selecting winding turns and wire size, motor nomenclature, basic assembly, bench testing and much more. It has been purchased and used by clubs and individuals all over the world. It runs about 1 hour and makes a great club program. It's great for first time builders, but even experienced builders will learn a few things.

Good call jbatch! I wonder what other stuff could be moved to this category from "Power Systems" to give this a jump start? All the Cd ROM Part 1, part 2, etc..construction threads come to mind.

Hey guys, I really need some help picking out magnets for my cd-rom motor. I wound it with 17 turns of magnet wire I got from radio shack, not sure what gauge but it's small and red.... I used 2 bearings and thats all I can really say about it. I know I want 12 magnets in there but what size, what do you guys need to know to help me. how do I determine the Kv of the motor. I want to use it on my piccolo. I will try to post some pics. and what does the number of turns do, should I use more or less or stick with 17? it looks awesome and spins very nice and true, doesn't look any different than the ones the more expierenced guys have made, I had the stuff laying around, figured I may as well do it. thanks guys.

Motor mounts


Different companies find their way to design motor mounts. Some of them specailly for their motors, some other are very standard. Take a look and pick yours.

I'd say keep the chitchat to another thread and leave this one for pointers to "DIY motor tools and parts sources"

Here's mine I just recently found, although it's geared towards audiophiles it got great calc tools which any motor builder can use!!!

I just got some of these stick mounts. https://www.rcgroups.com/forums/showthread.php?t=459391

They are very cheap, very light, and hold the motor very well.
