Are there alternators with 3+ phases?

Question

Electronics

If 3 phases are arranged with a shift of 120 degrees in order to efficiently use the energy of the torque of the rotor, is it possible to make, for example, 10 such phases? (The shift will be 36 degrees).

Answer 1

It is possible . But not generators, but engines. And the goal will be different - not performance, but accuracy and smoothness. We are, of course, talking about synchronous motors.
And the generators, alas - no more than 3x. The productive use of the rotor torque in them is provided by its moment of inertia.
