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...

Performance Comparison of Dual-Rotor Radial-Flux and Axial-Flux Permanent-Magnet BLDC Machines

A novel machine family – dual-rotor, Radial-Flux, Permanent-Magnet (RFPM) machines -has demonstrated that it can substantially improve machine torque density and efficiency. The objective of this paper is to provide a performance comparison between two major alternatives of this technology: Surface-mounted dual-rotor RFPM machines and Axial-Flux Permanent-Magnet (AFPM) machines. The comparison ...

Permanent Magnet Linear Transverse Flux Motors

The transverse flux machines (TFM), introduced at the beginning of the 80’s, are possible solutions for diverse applications requiring special electrical machines [1]. The researches have focused until now mainly on rotary TFMs. A new type of permanent magnet linear transverse flux reluctance machine is proposed here. Such machines can be successfully applied for example in conveyor application...
