Castle Motor Repair Kits

Were/Are the CC/Neu motors "based off of" Neu motors, or did Steve Neu actually "help build" or "provide plans for" the motors? I think that would make a big difference.

Steve Neu actually provided all of the design plans (stator, rotor, etc.) for the Castle/Neu motors. Steve also trained our people how to correctly wind the stators for maximum performance, provided all tolerances and specifications, testing requirements, etc.

We decided to use a Kevlar wrap rather than a carbon wrap because of availability of carbon was very bad when we started producing the motors (there was a 52 week lead time on the carbon -- kevlar was available off-the-shelf.) Also, we were able to automate the kevlar wrapping technique.

Carbon is a little stronger than Kevlar, but we were able to pack a little more kevlar with the automated winder. So the strength was on par with the carbon wrap. There is a disadvantage to using Kevlar vrs carbon in that if the wrap fails, carbon just slowly turns to dust (because it pulverizes in the gap between the rotor and stator) where kevlar turns into hard little balls that gums up the gap. We haven't had any issues with this, however, because the epoxy we are using to hold the Kevlar is extremely good... We've only seen a few very minor wrap failures.

The main differences between the Castle/Neu and the Neu motor are: The Castle/Neu uses the Kevlar wrap, the Neu motors use a carbon wrap, the Castle/Nue uses a larger bearing (mainly because of higher side-loads in cars,) the Castle/Neu has closed end-bells (to prevent dirt/dust getting in the motor) and the Castle Neu has a ribbed case (for cooling.) The Castle/Neu motors are made in Castle's facility in China, while the Neu motors are made in Steve's facility in San Diego.

We pay Steve a royalty for every Castle/Neu motor produced. Steve is also working with us on several new designs. Castle is also Neu motor's North American distributor. We have a very good working partnership with Neu motors.

Oh, I forgot! There's one other major difference in the Castle/Neu motor -- the Castle/Neu motor uses a keyed shaft and rotor -- mainly because shock loads are so high in cars. That's why you never hear about a Castle/Neu rotor slipping on the shaft.

I have to give credit for this to our engineers in China -- they came up with a very clever solution to key the rotor to the shaft.

I noticed this when i had to reglue a magnet, very clever using the keyways
