Radial Force Control of a Switched Reluctance Motor with Two-Phase Sinusoidal Excitations [PDF]
[[abstract]]Due to its special structure, the shaft radial force and torque of switched reluctance motor can be separately controlled by proper selection of pole currents. When all the pole currents are controlled independently, it is possible to produce
