EESMs generally are not great at city driving cycles compared to IPMSMs. They do really excel in field weakening at moderate torques.

Niron is not developing an EESM. They are developing Iron Nitride permanent magnets. These magnets can be used in a variable flux permanent magnet synchronous machine (VFPMSM). Var…

I am a little surprised that Renault is only claiming a drive cycle efficiency of 92% (unclear for which drive cycle). It is possible to design EESM with brushless high frequency r…

Thanks for the recommendation. Do you have any other recommendations for low cost/homebrew lithography?

Do you have any photomask vendors that you recommend. I am trying to do some homebrew lithography and the photomask is not coming out as crisp as I want.

The innovation here is in the packaging, fitting the brushless inductive power coupling for the field excitation inside the shaft. T he idea of using a high frequency rotating tran…

What sacrifice would you say that the Bode 100 makes in performance (Especially compared to the E5061B)?
