DESIGN OF ELECTRIC MACHINES: Axial Flux Machines

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...

Stator-Flux-Oriented Based Encoderless Direct Torque Control for Synchronous Reluctance Machines Using Sliding Mode Approach

In this paper a sliding-mode torque and flux control is designed for encoderless synchronous reluctance motor drive. The sliding-mode plus PI controllers are designed in the stator-flux field oriented reference frame which is able to track the mentioned reference signals with a minimum pulsations in the state condition. In addition, with these controllers a fast dynamic response is also achieve...

Integrated, variable-reluctance magnetic minimotor

The use of lithography and electroplating to fabricate variable-reluctance, nearly planar, integrated minimotors with 6-mm-diameter rotors on silicon wafers is described. The motors consist of six electroplated Permalloy@ horseshoe-shaped cores that surround the rotor. Copper coils are formed around each core. The Permalloy and copper electroplating baths, electroplating seed layers, and throug...

Flux 2dinteractive Design of Electrical Machines and Systems

The design of electromagnetic systems must take into account the spatial distribution-of magnetic flux density. The conjuction of field computation and C.A.D. t echniques lead to in te rac t ivecomputer aided design systems like FLUX, based on the finite elements method. By graphic display, the designer check his data and prepare the finitt elements mesh. The post-processor allows him to get th...
