ralph your english is much better than google or babbelfish's translations of german lol. and with the FEMM optomised stator design made using very thin laminations of high quality material the Croco is guaranteed to perfom very well!. is there any information or drawings for that stator carrier? eg what size bearings? and i see from the drawings an 8mm shaft, will these be sourced along with the bells and magnets? or will we have to source these parts ourselfs?

Ralph, on your web site you say "The middle part should be made from steel too". Can you confirm please that you mean the stator holder that the bearings go into. I normally make this from aluminium; does it improve efficiency to make it from iron?
Thanks, David.

There is hardly any magnetic flux in that part of the motor David, therefore from a magnetic point of view, it makes no difference what material you use.

Some of the drawings for the the stator plates appear to have holes in the center. Is FEMM being used to assure the stator isn't saturating around the holes?

Hi,

I am very interested in ordering 180-200 stator plates but I was wondering if you or http://www.neodyme-magneten.de/ are going to produce the can and if so how much. I was also wondering how much will the magnets be.

Thanks, Andrew

i do hope there is a standard reached for the stator carrier but if worst comes to worst i know of a few sources here at rcg who may do a limited run of cans and stator carriers for us, the design work has already been done for us for the can, and i'm sure that ralph will make dxf/dwg drawings available for the can and some kind of mount?, if not i can draw up a mount if we who will be needing parts can agree on a design.

Sorry me to jump too late:

Can the stator plates be machined with laser or other cnc machines ?

How can it be insulated before cutting?

Cheers.

thanks for the updates ralph. making a modular stator carrier is an excellent idea! this should help keep the costs for machining these parts to a minimum as all will need a top and bottom piece only a different length tube. are you planning on trying to make the can modular too?
