New linear hybrid reluctance actuator
Andrada Gascón, Pedro; Blanqué Molina, Balduino; Martínez Piera, Eusebio; Torrent Burgués, Marcel; Garcia Amorós, Jordi; Perat Benavides, Josep Ignasi
In this paper a new type of hybrid reluctance
actuator is presented. This linear hybrid reluctance actuator is a two phase double sided actuator in which the stator is composed by four normalized U cores, each with a coil wrapped around the yoke connecting the two arms of the core
or with two coils wound on each of the arms and a permanent magnet placed near the air gap between and in contact with both arms. The mover is comprised of rectangular poles
without connecting iron pieces between them but mechanically joined by non-magnetic mounting parts. The magnets are
arranged so that their flux is in parallel to the flux created when the coils are energized, both fluxes are added and the
total reinforced flux links the stator and the mover. But when no currents flow through the coils no flux crosses the air gap,
and the flux of the magnets is closed through the back iron that supports them. An analysis and simulation of the motor
using 2 D finite element and MATLAB Simulink is carried out. Finally, a comparison of this type of actuator with respect a linear reluctance stepper motor of the same size is shown.

Thermal performance analysis of the double sided linear switched reluctance motor
Garcia Amoros, Jordi; Bargalló Perpiñá, Ramón; Andrada Gascón, Pedro; Blanqué Molina, Balduino
This paper presents a study about the thermal
performance of the double-sided flat Linear Switched Reluctance Motor (LSRM) according to the number of phases (m) and the pole stroke (PS). The analysis is performed by
means of the Finite Element Method (FEM) for
electromagnetic computations and a lumped parameter for thermal model (LPT) both linked to an optimization algorithm
based on the Response Surface Methodology (RSM) in order to reduce the computing time. The results show the LSRM behavior for achieving an optimal design from the point of
view of the thermo-mechanical performance for a given insulation class and a duty cycle operating conditions.

In the next years is expected an important rise in sales of electrical scooters in the entire world but especially in China. In order to address this challenge the electric scooter industry has to be more competitive in the transportation market and therefore important improvements, in terms of energy density and costs, have to be done in the electric storage system and in the electric propulsion system. In this paper, an analytical and experimental comparison of two different drives for electric scooters is carried out. Both are permanent magnet synchronous outer rotor motor drives but one placed inside the rear wheel and the other connected to the wheel trough a mechanical transmission.

Minimization of torque ripple in switched reluctance motor drives using direct instantaneous torque control
Castro Soriano, Javier; Andrada Gascón, Pedro; Blanqué Molina, Balduino
Torque ripple is an inherent characteristic of switched reluctance motor drives due to its double salient geometry and it is a serious drawback in applications that require
smooth torque and high dynamic performances. This paper presents some contributions to the minimization of torque ripple in SRM using direct instantaneous torque control (DITC). Direct torque controller is simulated using Matlab/Simulink and then
implemented in a DSPACE ACE kit 1006 CLP that includes a processor board with an AMD OpteronTM running at 2.6 GHz.
Finally, experimental results are shown and they are compared with those obtained using conventional angle control.

New hybrid reluctance motor drive

In this paper a new type of hybrid reluctance
motor drive is presented. This new motor is characterized by a stator formed by the combination of independent magnetic structures composed of an electromagnet, the magnetic core with one or several coils wound on it, associated with a permanent magnet disposed between their poles. The rotor has the same configuration of a switched reluctance motor without coils, without magnets and without squirrel cages. A
particular case of this hybrid reluctance motor is studied in which the stator consists of three electromagnets with
permanent magnets, constituting each one of them one phase of the motor, and the rotor is formed by five salient poles.
Then an analysis and simulation of the motor is carried out.
Finally, experimental results and a comparison of this type of motor drive with respect switched reluctance motor drives of
the same size are shown.

Torque ripple is an inherent characteristic of switched reluctance motor drives due to its double salient geometry and it is a serious drawback in applications that
require smooth torque and high dynamic performances. This paper presents new contributions to the minimization of
torque ripple in SRM using an enhanced direct instantaneous torque control. Torque ripple is reduced by adding a PI controller before the instantaneous torque controller and a change in the commutation zones. The PI direct instantaneous torque controller (PI+DITC) is simulated using Matlab/Simulink and then implemented in a DSPACE ACE
kit 1006 CLP. Finally, experimental results are shown and they are compared with those obtained using conventional direct instantaneous torque control.

Experimental determination of magnetic characteristics of electrical machines
Andrada Gascón, Pedro; Martínez Piera, Eusebio; Perat Benavides, Josep Ignasi; Sánchez López, José Antonio; Torrent Burgués, Marcel
A test equipment for determination of magnetic characteristics of different kinds of electrical machines is presented. Experimental determination of magnetic
characteristics of electrical machines should be understood, according to the machine studied, as determination of their
corresponding inductances or as determination of their magnetization curves (flux-linkage versus current for different
rotor positions).
The test equipment is based on a method of measurement of inductance by means of D.C. current, proposed by C.V. Jones, in
which a bridge arrangement is used in order to eliminate the resistance effects. This equipment is able to obtain armature
inductance in DCM (direct current motor), d-axis and q-axis inductance in SPSM (salient-pole synchronous machine) or
SYNCREL (synchronous reluctance motor) and magnetization curves of SRM with a good accuracy and in an automatic way.
The main advantage of this setup is that it is an automatic system controlled by PC, that allows magnetic characteristics of
almost any electrical machine to be obtained, reducing measurement time and manual errors and providing easy and
user friendly presentation of the test results.
Several examples of experimental determination of magnetic characteristics using the proposed equipment are shown proving their test capabilities.
