Abstract. The article analyses generators generating efficient electricity at low speed water and wind
flows. High rotating speed generators are used in wind farms and micro-hydropower. Reduction gears are
used to provide the generators with the required number of rotations. The use of reduction gears in the
power system leads to a decrease in the efficiency of the system and additional capital costs. The study
analyzed multipolar synchronous generators. Both generators used a permanent magnet to generate
electromotive force, and the generators are distinguished by the radial and axial placement of the permanent
magnets. In order to analyze the generators, virtual models were created and analyzed in the Ansys Maxwell
program. The Ansys Maxwell program is used to analyze electric machines in the electromagnetic field.
The use of these programs in determining the optimal size of new devices is of great importance in saving
time and improving cost-effectiveness.
