9. Scientific Interests
The research interests of Fabrizio Marignetti include the design, the analysis and the digital control of synchronous PM machines, especially axial-Axial flux machines, linear machines, tubular actuators and generators. Recently, he has devoted his interests also to the design of integrated electronic and electromechanical systems, of speed and position sensorless electric drives, power converters, power energy conversion systems for renewable sources, cryogenic electrical machines and unconventional materials.
His scientifi.c production is testifi.ed by more than 160 papers published both in international journals and in proceedings of international conferences. The publications deal mainly with di.erent design aspects, such as core losses, thermal modeling, eff.ects of eccentricity, end-winding mutual and leakage fl.uxes.
Both numerical methods and analytical procedures have been used. The experimental activity is directed towards the design, construction and veri.fication of machine performances.
Some results achieved in the main research areas are summarized below.
9.1 Axial Flux Machines
The armature MMF distribution of axial flux synchronous machines with fractional slot windings is especially rich in harmonics. Slotting also generates fl.ux-density harmonics. These harmonics are responsible of increased core and rotor losses.
An analytical model for the computation of stator and rotor core losses including magnet losses was carried out. Multiphysics electromagnetic, thermal and .fluid dynamical modeling allowed to map machine temperatures. Both measurements and thermal mapping with thermal cameras spotlighted high temperature levels in the rotor of one prototype. To further investigate core loss
production, a range of machines has been built using soft magnetic composites both as stator and rotor core material.
The compounds used were bonded iron powders, charged resins and charged polymers. Of these, only one is commercially available, while the others were specially made.
The machines built have been characterized to show the link between the power density and the iron volume fraction. Rotor iron losses decrease using SMC cores. However, MMF harmonics contribute to saturate the rotor, aided by the low rotor permeability. This generates a rotor anisotropy that has been experimentally verifi.ed.
Also, the e.ffects of rotor eccentricity on torque and back EMF have been investigated and a method to assess the eccentricity has been carried out.
9.2 Control of Electric Drives
The high number of pole pairs of axial .flux machines harm the precision of speed and position sensorless drives. The same issue is found in low speed linear generators. To overcome this limitation and increase control robustness, sliding mode techniques have been used and validated.
A speed and position sensorless control technique has been also implemented in an FPGA, allowing to build a system-on-programmable-chip permanent-magnet synchronous-motor drive. The system was simulated at gate-level and with hardware in the loop simulation and was experimentally validated.
Although voltage source inverters are widespread in low and medium power electric drives, current source inverters (CSI) may represent a valid alternative if voltage control techniques are used. Fabrizio Marignetti investigated the advantages of CSI in electric drives and proposed an improved voltage control algorithm for CSI. The proposed algorithm achieved a better THD and a
smoother voltage spectrum in the experimental tests in comparison to standard PI control.
A Zero-Current-Switching CSI was built. Among its main advantages are: low conduction and switching losses, inherent output .filtering, capability of withstanding short circuits. A control law for ZCS CSI was developed, in order to damp the resonant modes that are generated by the load.. filter interaction.
Both series and series-parallel hybrid electric vehicles require two machines: one acting mainly as a generator, the other as a motor. An axial .flux PM synchronous drive with two independent rotors was designed. The synchronous machine with axial airgap has one stator and two rotors with permanent surface magnets and diff.erent pole pairs number. The control model is developed for a single inverter that produces three phase output voltage with two frequencies components; the torque current for each rotor is controlled through the stator current that fows in the two serial windings.
9.3 Tubular Linear Machines
Fractional slot windings allow increasing the frequency of low speed linear machines. A prototype of fractional slot linear tubular machine was built and tested. Tubular machines can be used as low speed generators for reciprocating energy sources, such as wave and tidal energy. The design of low speed linear generators does not follow standard procedures, as the values of their reactances are in the same order of magnitude as the winding resistances. A design optimization procedure for linear tubular machines for the Inertial Sea Wave Energy Converter(ISWEC) has been carried out. This floating wave energy converter is fully enclosed in a sealed tank, slack-moored to the seabed and uses a gyroscope to convert wave energy into alternative motion. A linear tubular generator was built and tested in the ISWEC.
A multiphysics thermal and .uid dynamical numerical analysis of linear generators for deep ocean and .oating wave energy converters has been carried out, showing the heat exchange possibilities off.ered by diff.erent sea energy converter
layouts.
A degree of translator eccentricity is inevitable in tubular linear machines. It leads to an increase in radial forces normal to the machine shaft that bend the translator. An analytical model of normal forces taking into account translator eccentricity was carried out and validated by experiments.
9.4 Cryogenic Machines
In the years 2003 -2005 prof.Marignetti participated as a design specialist in the team that built the fi.rst Italian superconducting transformer. Afterwards, he envisaged a numerical technique to optimize the design of a three phase air-core HTS transformer.
The use of Superconductors is generally limited to large machines, although Fabrizio Marignetti demonstrated that cryogenic cooling allows to design more compact and e.cient electric machines with copper windings. To investigate the possibility o.ered by cryogenic-cooled copper windings, Fabrizio Marignetti built a linear tubular PM syncronous actuator with liquid nitrogen cooling.
Among the other advantages shown in the experiments, this machine showed a natural short circuit self protection capability.
Magnesium diboride is a well known HTS material. Recent progresses in manufacturing allow it to represent a cheap alternative to other superconductors. An axial .ux machine with bulk MgB2 magnets and cryogenic cooled copper stator windings has been built and is currently under test at ENEA.
