Изобретение касается асинхронной электрической машины, в которой вращение ротора относительно статора обеспечивается электрически проводящим покрытием. Воздушный зазор между ротором и статором соответствует формуле:
Figure 00000001

где Dr - наружный диаметр ротора (мм), Ds - внутренний диаметр статора (мм), U - окружная скорость (м/с), δ - величина воздушного зазора (мм), А-постоянная величина которой ≥ 0,3, предпочтительная - 0,7- 1,5, проходящая 1, измеряется в мм, B-постоянная, величина которой ≤ 150, предпочтительная 50-100, проходящая 70, C-постоянная, величина которой ≤ 1200, предпочтительная 300-600, проходящая 400, измеряется в м/с на миллиметр. Окружная скорость ротора больше 100 м/с. Кроме того, упомянутый ротор обеспечивается в сочетании с телом вала или подобным ему элементом электрически проводящим покрытием, которое конструируют так, чтобы оно непрерывно простиралось по всей площади рабочей поверхности ротора.The invention relates to an asynchronous electric machine, in which the rotation of the rotor relative to the stator is provided by an electrically conductive coating. The air gap between the rotor and the stator corresponds to the formula:
Figure 00000001

where D r is the outer diameter of the rotor (mm), D s is the inner diameter of the stator (mm), U is the circumferential speed (m / s), δ is the air gap (mm), A is a constant value of ≥ 0.3, preferred - 0.7-1.5, passing 1, measured in mm, B-constant, the value of which is ≤ 150, preferable 50-100, passing through 70, C-constant, the value of which is ≤ 1200, preferably 300-600, passing 400 It is measured in m / s per millimeter. The rotor speed is more than 100 m / s. In addition, the above-mentioned rotor is provided in combination with the shaft body or similar element with an electrically conductive coating, which is designed to extend continuously over the entire area of the rotor working surface.
