Abstract
In high-speed machines, the rotor mechanical design often become more critical that the electromagnetic or thermal design. The main focus is to find out and reduce the mechanical stress distribution in the rotor’s component parts. For preliminary mechanical design, the analytical approach is used. Further design and optimization implies 2D finite element analysis. In this paper, two types of permanent magnet rotors (with surface-mounted magnets and with buried magnets) are modeled and analyzed.
Keywords: high-speed motors, mechanical design, tensile stress, permanent magnet rotors
