Electromagnetic Moment Increasing of Superminiature Electric Motor with Excitation by Rare Earth Permanent Magnets

The article is devoted to the issues of increasing the power and torque on the shaft of a subminiature electric motor with excitation by permanent magnets based on rare earth materials. The essential feature of the design of the electric motor in question is a glass stator made by polycapillary fiber technology. The motor excitation system is a two-pole permanent magnet. The values of magnetic induction and electromagnetic moment for several variants of the rotor design were obtained by finite element modeling.
