Abstract

Inductance value of an electrical machine is important for high-speed electrical drives. In this paper, a comparative analysis of inductances of toroidal, skewed and concentrated air-gap windings has been performed. Analytical approach of inductance calculation, using Biot-Savart’s law and method of images, is applied to toroidal and concentrated windings. The analytical method of inductance calculation is verified by FEM 3D. Additionally, comparison of the conductor length of the windings is performed.
