ok, thanks for the explanation.
Do the math for weight of the components, and compare with an engine driven propeller using a reduction gear to get the optimum tip speeds, and see what the added weight will cost. Then factor in generator losses.
I think your idea lends itself to low speed high lift aircraft, where the weight penalty gets absorbed better.
High speed regime, weight is king. Inline losses alone make it impractical.
