did you see that?

adason · 12th January 2010, 02:23 AM

I'm afraid I can't tell you right now. It's a multimillion dollar project and the application is very serious.

If it's really a ' multimillion dollar project', why asking for help from a bunch of audio freaks?

Edit: Perhaps this company is willing to design a motor according to your specs: http://www.magneticinnovations.com

... because some of us are real experts...

You could try approaching a custom switched reluctance motor manufacturer with your application. These can have very high torque at low speed, but optimized speed/number of poles will have to be calculated with the volume of the resultant gear stack and maximum power output available for given motor configuration. This motor type doesn't have a wound rotor and so the IR heat can be drawn away easier with available fluid cooling.

Does it have to be electric? There are some very strong compact hydraulic motors out there

Efficiency is important also low weight.
