In this study, a low-cost, innovative, and non-intrusive rotor position detection system and the phase excitation algorithm were proposed for the external rotor switched reluctance motor (ERSRM). The benefits of the developed rotor position sensing system are its low cost and the accurate detection of the starting position of the rotor. Also, the rotor speed was calculated in real-time using the developed system. Another benefit is that the phase excitation signals are directly generated from this system. Therefore, the complexity of the control algorithm is reduced. To prove the effectiveness of the position sensing system, the motor was operated with the proportional–integral (PI) speed controller. The designed speed controller was implemented on the Texas Instruments (TI) TMS320F28379D Launchpad and experimentally tested. The control results given in section 4 showed that using the phase excitation signals coming from the developed Hall effect sensor-based rotor position detection system, the motor was operated successfully with low torque ripple. A comparison was made between the presented technique and the state of the art in terms of torque ripple, and it was explained in the conclusion section.
