Generally, the demagnetizing field for magnets is reduced by positioning the magnet deep inside the rotor, which helps to ensure a magnetic flux path
on the q-axis and increases reluctance torque.
The ferrous particles aligned along the flux path
creating particle chains in the fluid.
The actual torque computation is done by integrating along the entire flux path
under half of the slot opening .

Mutually Coupled Switched Reluctance Machine", Ph.
where reluctance R is the inverse of permeance, the flux path
length for each element is L, and flux path
width W is simplified to the width of the core.
Figure 5(b) shows a flux barrier rotor made of standard flat laminations, where the flux barriers are punched in the traditional way in order to obtain the preferred flux path
Unlike the radial flux path
found in most conventional motors, the flux flows through the stator parallel to the shaft.
The rings and hubs comprise the flux path
for the electromagnet and must have a tightly controlled carbon content.
This is a 25 percent increase in torque over earlier models and the higher torque is produced by a triple flux path
within the unit.
Other critical requirements included the use of an all metal enclosure to provide a closed flux path
for the permanent magnet, and ruggedness.
The unique magnetic flux path
design reduces reluctance and therefore increases efficiency.
Based on investigation using TDFEM on the accurate flux density of all part and flux path
of the induction motor, the proposed induction motor has the merits like higher efficiency, lower losses and good torque makes the SCRIM more suitable for automotive traction application.
