    Direct drive wind turbine rotor design

    Hi We were working for awhile on developing a blade profile for a high speed direct driven wind generator. To make a long story short, we are wasting time and resources and getting nowhere. Blade design is specialized work and we don't have the knowledge and resources. Therefore: does...

    TiN vs. TiAlN coating

    I have an application, a cylindrical guiding rod that has a coil spring running along it and loading a device that slides on the rod. It is a long spring, and due to the compression/detent there is high wear on the rod; the spring/rod interface is lubricated, but it operates mostly on a boundary...

    Frameless alternators for wind power generation

    Hi. Is there a north american manufacturer of low power (3-100Kw) frameless tri phase frameless alternators that can be integrated into a direct drive wind turbine? I would appreciate any info and links on this matter. Thanks.

    Drive shaft calculations.

    Here's the problem I'm facing: I'm working on a development project for a low power wind turbine. The concept has been defined and a couple prototypes were built but no calculations heve been made to size the transmission shaft, housing and bearings. The prototype has a straight shaft with the...

    Chrome re-plating

    I have a few small parts whose thin chrome plating peeled of in some areas. The base metal is brass and I want to redo the coating. Before re-chroming the old coatoing has to go, but which is the best way to strip it down? As the base metal is soft, bead blasting would damage the surface. Any...

    Blueing steel parts

    Again, this is NOT for a volume production setup but for finishing small lots of parts, small screws in my case. I know it is done in an oven, a thermo-chemical process that deposits a nice, thin, blue hemamtite layer on the surface of the parts. What I don't know though, and I need your help...

    Satin finishing on soft steel stamped parts

    Greetings! It's not for an industrial setup but for adding a finish touch to small stamped components. Rather than rubbing on a fine grit emery paper sheet, how else can I get a satin finish? It's not for volume production, and components are micro mechanical parts. Thank you.

    chemical polishing

    Hi. I'm looking for a process to add/restore a mirror finish to a stainless steel surface. I know chemical polishing is the solution however it is difficult to find any documentation on the processes. I'm not looking for industrial scale processes for high volume production. Any help would be...
