Abstract—There has been a growing interest in switched reluctance motor (SRM) ever since the development of thyristor in. The most. The switched reluctance motor (SRM) drives for industrial applications are of recent origin. Since , a variable reluctance motor has been proposed for. Switched Reluctance. Motor Features. A switched reluctance (SR) motor is a rotating electric machine where both stator and rotor have salient poles. The stator.

Figure 5. Flowchart steps in Design.

Figure 7. Discretization switched-reluctance motor geometric. Finite Element Analysis Finite element analysis is used to predict the torque produced at various currents and rotor positions.

The time stepped FEA, is the most accurate method available to obtain the magnetic characteristic in an electromagnetic device, like for switched reluctance motor. The following assumptions are made for simulating the magnetic field distributions inside switched reluctance motor [7]. The numerical method finite element analysis used to gives a better understanding of flux distribution inside the motor.

The flux linkage, the excitation currents and the torque developed by the motor is also determined under current forced conditions. The design the switched reluctance motor becomes complicated due to the complex geometry of the motor. The reluctance variation has an important role in the Figure 8.

Flux pattern in align position 20A. An accurate knowledge of the flux distribution inside the motor for different current excitations and rotor position is essential for the prediction of performance of the motor. The motor is highly saturated under normal conditions and so that the nonlinear magnetisation characteristic of the core must be taken into account when the flux distribution is computed. All these aspect are included in finite analysis with.

The following assumption are made in determining the magnetic field distribution inside the motor[8]. Zoom of flux pattern in align position.

The flux densities in other parts of the motor are very much less. Flux Distribution in Align Position V. The aligned and unaligned flux linkage plots for the conventional switched reluctance motor are shown in the corresponding figures fig.

The flux characteristic versus excitation current in fig. Flux Distribution in Align Position The flux density distributions inside the motor for aligned positions of the rotor are shown in fig. Figure Flux pattern in unalign position 20A.

Finite element analysis base on COMSOL software have been used to accurately estimate the unaligned flux linkages and torque. Figure 12 show torque versus rotor position of the SRM model, from figure we can describe that maximum torque rotor at 20 degree axis, and from fig. This model provides a more realistic behaviour of a true SRM motor that describe Figure Zoom of flux pattern in unalign position 20A. The result is useful for machine control in order to give a smooth data for The flux density distributions inside the motor for machines control.

Incremental mechanical energy for rotating machine is given This study is mainly focused on simulate the influence of by excitation current in flux linkage, and rotor position in 3 torque profile based on COMSOL software. So the electromagnetic torque is 4 III.

The motor has some constant excitation current. For constant current, the six stator poles, the rotor has four poles. So average torque can be computed from the area enclosed between the flux lingkage curve for some constant excitation current using magnetitation curves shown in fig.
