Design and Analysis of 42-V Coreless Axial-Flux Permanent-Magnet Generators for Automotive Applications
Saeid Javadi, M. Mirsalim
(May 2006 – July 2010)
This project presents the design and analysis of a novel structure of an axial-flux permanent-magnet machine with ironless stator to generate sinusoidal electromotive force with very low harmonics. The structure is of a special design that is suitable for flux weakening in variable speeds. Flux weakening is done by a mechanical actuator to change the position of windings relative to each other. To confirm the machine performance and the design, analytical and three-dimensional finite-element numerical methods are implemented. The simulations results of the proposed generator coincide very well with the experimental results on a prototype 42-V system realized in the laboratory.
A Coreless Axial-Flux Permanent-Magnet Generator for Automotive Applications
Saeid Javadi, M. Mirsalim
(May 2006 – July 2018)
We present a modified structure of an axial flux permanent magnet generator for an automotive application. The generator has a coreless double-stator structure; one is stationary, and the other can be moved to achieve the desired performance. This provides a simple mechanical way to weaken flux in order to extend the speed range of the generator for a constant output power. The excitation is from permanent magnets mounted on the rotors, and the windings are concentrated with simple circular form to achieve a sinusoidal waveform with very low harmonic contents. We have designed and analyzed the generator by both the three-dimensional finite-element method and the analytic approach. The calculated values coincide very well with the experimental results.

Double-Sided Linear Induction Motors
Mehran Mirzaei, M. Mirsalim
(February 2002 – October 2003)
In this project a Double-Sided Linear Induction Motors was designed and constructed. This motor has a double-sided stator and a solid rotor. Because of the special structure of this motor, electrical and magnetic circuit lengths of the stator should be very smaller than the rotor one.
