Best overall dimensions of synchronous generator with permanent magnets for small power wind plants and micro hydropower plants

Annotatsiya

The overall dimensions of a synchronous generator with permanent magnets are determined by its main dimensions - the length lp and active part of the rotor with a diameter Dp , so the larger the air gap, the smaller the magnetic induction in it and vice versa. The force of gravity, in turn, will also depend on the air gap. The structurally incorporated unevenness of the air gap leads to an increase in the attractive force in the place of the smallest gap value, which leads to the appearance of a bending moment. As a result, the disc skews and the load on the bearings increases.
