Motor Parts
ý GoBrushless
These guys mainly deal in small aircraft motors, but their rotor designer is a godsend. They also sell stock stators in the 50mm and 60mm size range.
ý Super Magnet Man
Reputable dealer of stock AND CUSTOM! neodymium high strength magnets. All of my motor magnets have come from him. George is a friendly person to deal with and chock full of all kinds of magnet information.
Custom magnets from George generally take 3 to 4 weeks to manufacture and are priced only slightly above stock magnets. This is absolutely phenomenal: For a bit more cash, you can have a full circle of magnets customized to your motor.
ý Protolam
These guys supplied the iron for the BWD Scooter gratis. They have in house punches and LASER cutters and will make small quantities for your experimentation
ý Your local motor shop
Got a local electric motor rebuilder? Give them a visit. They'll be glad to see a motor which doesn't require a forklift and 8 guys to handle. High-grade magnet wire and potential harvestable motors.
General Parts
ý Hobby King
A certified legit™ hobby products dealer out of Hong Kong. Mind-blowing pricing on everything, and they make no attempt to hide the fact that their products are Chinese in origin. You can put together an entire EV hacker powertrain just from the parts on this site. Stock up on lithium batteries before the Fed regulate bare Li packs out of existence.
Their large outrunner motors are inexpensive enough to consider cannibalizing for stators.
ý McMaster-Carr
I shouldn't even have to mention these guys. If you can think of it, they probably carry it, else it's not worth buying. Magnet wire in "huge" and "holy crap" gauge, raw materials, bearings, adhesives, and hackable wheels are just a few motor-relevant things I can think of that you can find there.
ý Kelly Controller
Purveyors of fine (Chinese) motor controllers in sensored, sensorless, both, and neither (DC). Their KDS line of mini-controllers will be perfect for your small sensored hub motor. You can also be lazy and just buy one from them.
ý VXB Bearings
Because all legit bearing manufacturers have 3 letter names. Inexpensive bearings for your motors. I've gotten all my bearings for everything I've built from here. Everything I've built since discovering them, that is.
ý Speedy Metals
Where I got my Giant Steel Death-Tube from for Razer's motor. Get raw materials for the mechanical structure of your motor here.
Knowledge and Reference
ý The Southern Soaring Club Reader Articles
Contains one the best brushless motor primer I have seen. Electric Motors part 1 - 5 is worth a read to get more background on the matter.
ý Emetor Brushless Motor Designer
Everything I just said and more wrapped up in a handy spreadsheet style calculator! Forget "4 * N * B * L * R", it will give you everything from back EMF profile to torque ripped to phase voltages and inductances. To use it properly, you MUST know critical dimensions and materials of your motor. But it's about as close as you can get to building it and throw it on the dyno.
ý Powercroco
This site is a veritable platinum mine of motor information and theory... if you can read German. Alot is lost in translation if you use an automatic translator, so find your nearest German guy and press him into service? Dr. Okon is the progenitor of the famous and useful Kombinationstabelle.
ý The RC Groups Motor Design and Construction forum
Always welcoming of newcomers and people with questions. The Crazy German R/C Airplane Guys here represent a vast majority of all motor limits-pushing that has occured in the hobby.
ý LRK Torquemax
Learn more about the background of the LRK winding here.
ý My site.
Not to be one to self-plug, but I have a bad good habit of keeping detailed build logs about EVERYTHING. Documented are all the rebuilds of RazEr, its predecessor Snuffles, and my most famous creation, the LOLrioKart.
