Abstract

This paper presents the design and evaluation of a new axial-flux low-speed and high-torque matrix-rotor induction machine. Iron wires embedded in a cupper matrix comprise the solid rotor structure. Specific design and sizing equations are provided focusing on key rotor parameters: the iron/copper ratio and iron wire diameter. The analysis was carried out through analytical equations and three-dimensional finite element simulations. Based on the proposed design guidelines, A 20 HP, 250 rpm prototype was built and evaluated for experimental validation. Good concordance was obtained between the different stages of the matrix-rotor induction machine design: the initial sizing recommendations, finite element simulations and experimental results. Moreover, the proposed machine is suitable for low-speed high-torque applications, although there is room for further optimization depending on specific application needs.
