where L0 is the unsaturated inductance. The effects of saturation are more prominent as the product of current and unsaturated inductance approach the saturated flux linkage value. Specify this value using the Saturated flux linkage parameter. Differentiating the flux equation then gives the winding in...

Here—p is the number of pole pairs, Ld and Lq are d-q axes inductances respectively and id and iq are d-q axes currents flowing in the stator windings. As can be seen in Eq. (1) the main electromagnetic variables are the d-q axes inductances. As it was discussed previously, d-...
Switch reluctance motors (SRMs) have many advantages, such as easy construction, high reliability, low cost, and higher energy efficiency compared to the inductance motors. However, SRMs have a major drawback—severe torque ripple (TR), which causes a great deal of noise and movement. Hence, ...

Slid Mode Control of Switch Reluctance Motor Based on Torque Inverse Model
In the formula (1), Pn is the number of pairs of poles, Ld is the d-axis inductance, Lq is the q-axis inductance, Id is the d-axis current, and Iq is the q-axis current. Thus, the reluctance torque (output torque) T is increased by increasing the difference (Ld−Lq) between...
Where the Inductance (L(θR)) as a function of relative rotor angle (θR) can be determined from the following relationship; L ( θ R ) = ( 2 · N ) 2 Total ( θ R ) The torque (Tfld) produced by the pole pair on the rotor as a function of winding current (I...
