DESIGN OF ELECTRIC MACHINES: Axial Flux Machines

Comparison between Axial and Radial Flux Pm Coreless Machines for Flywheel Energy Storage

The need of a deeper understanding of coreless machines arises with new magnetic materials with higher remanent magnetization and the spread of high speed motors and generators. High energy density magnets allow complete ironless stator motor/generators configurations which are suitable for high speed machines and specifically in flywheel energy storage. Axial-flux and radial-flux machines are ...

Design of Axial-flux Permanent-magnet Low-speed Machines and Performance Comparison between Radial-flux and Axial-flux Machines

Thesis for the degree of Doctor of Science (Technology) to be presented with due permission for public examination and criticism in the auditorium 1382 at Lappeenranta ABSTRACT Asko Parviainen This thesis presents an alternative approach to the analytical design of surface-mounted axial-flux permanent-magnet machines. Emphasis has been placed on the design of axial-flux machines with a one-roto...

Analytical Modeling of Axial Collapse of Circular Hybrid Tubes

In this paper, considering symmetric collapse mode for hybrid tubes, and using Tsai-Hill fracture criterion to take into account the off-axis strength of an orthotropic lamina, an analytical model is extended and an expression is derived for mean crushing load and fold lengths of circular hybrid tubes. In this model, the influences of the geometrical dimensions including diameter, thickness of ...
