40mm, 18slot statorlaminations, group order
Ralph Okon (a.k.a. http://www.powerditto.de ) is putting together a group order for 40mm. diameter, 18pole statorlaminations. A minimum order of 5000 laminations is needed to start a production run. Minimum order per person is 50. One 0.20mm lamination (NO20 iron quality) will cost 0.5€. Flux ring and frontplates will probably also be available by then. Keep in mind, this is not a business for Ralph, he's in the business of curing people :-) More info on ordering; http://www.rcgroups.com/forums/showthread.php?t=392627 I'm posting this in several lists/forums, think it's best if we all discussed/asked in the thread above.

RE: How does a brushless motor work?
[quote]ORIGINAL: warren52nz I've been trying to discover how a brushless motor can turn at any speed other than the speed that the ESC is "telling it" to. My helicopter can't keep up the same rpm when it's on full pitch than it does at 0 pitch. So it seemed to me that the rotor would be getting behind the rotating fields which would cause God knows what sort of problems. [/quote]It's the motor that tells the controller when to commutate. These brushless motors are the same as brushed motors, only here the reversing of the voltage/current is done by the ESC, based rotor position and speed information from the motor.

That's why they have pictures :D You can use http://www.google.com/language_tools?hl=en for translation (not perfect, sometimes hilarious). Those stators are from computertapestreamers (Ditto, Colarado). Check out laserpriners, copiers and faxmachines too.
