group order: 40mm dia,18slot laminations. Turned parts can now be ordered.
Ralph Okon (a.k.a. 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

Ralph, have you considered a larger bore to take more robust bearings? I'm interested in swinging larger props (20-24 inches) in scale planes and it appears to me that I would have to use an 8x12mm bearing on the 'bell' end. These are at the bottom of the load range. A 16 or 18mm bore would allow 7x14 or 8x16mm bearings which can handle significantly greater loads.
Your views? Regards, David.

Ok, I just ordered the minimum number because I just don't want
to be left out. This looks like a truly exciting project. Do I need to order more?
Can you give some more details about the motor you have in mind?
I'm not really technical so I'm looking for Power converted in a way
I can understand. Will swing XX x XX prop. Is equivalent to X spec. motor
Will fly X helicopter. What kind of maximum Watts?
When will cans be available? Will there be a tutorial for this specific motor?
Thanks for the info.
