“…In 2003, Higuchi et al [9] proposed a single-phase switched reluctance motor with a tooth-slotted rotor design that used the magnetic saturation effect to produce starting torque in any position instead of using permanent magnets. In 2010, Jakobsen and Lu [10] presented a single-phase switched reluctance motor with four poles in the stator and rotor with a new stator pole design and an arrangement of permanent magnets to improve the starting torque.…”

This study proposes a novel, axial-flux, single-phase switched reluctance motor for micro machines with wireless-driven capability. The rotor and stator each have two poles, and the stator utilizes two permanent magnets to provide the required parking position and rotational torque. By reducing the number of magnetic poles and coils in the stator, and by utilizing a cylindrical design for its stator components, the micro motor is able to be easily manufactured and assembled. Safety and convenience are also achieved through the use of a wireless drive, which negates the need for power connections or batteries. This study utilizes the topology method in rotor design to reduce excessive torque ripple. For this study, an actual micro, axial-flux, single-phase switched reluctance motor with a diameter of 5.5 mm and length of 4.4 mm was built in combination with a wireless charging module and motor circuitry found on the market. With an induced current of 0.7 A, the motor achieved a maximum of 900 rpm, indicating possible applications with respect to toys, micro-pumps, dosing pumps, and vessels for gases, liquids, or vacuum that do not require feedthrough.

“…Limitations include unidirectional control and torque uncertainty in some positions that then rely on design imperfection and inaccuracies for starting. Other techniques proposed use saturable stator pole extensions [5], [6], asymmetric stator pole extensions [7], stepped rotor poles [8], or auxiliary starting windings [9], [10]. The drawbacks of these techniques are difficult construction, unbalanced radial force, unreliable starting, and low copper utilization, respectively.…”

This article presents a technique that uses rotor shorting rings to start the single-phase switched reluctance (SR) machine, from any rotor position, in a specified direction. It also outlines how the shorting rings enable starting of the machine. Transient finite-element analysis is used to illustrate the torqueproducing mechanism from the aligned position using the rotormounted shorting rings. It is also used to determine the optimal stator and rotor pole arcs and shorting ring design for a 200-W prototype machine. An SR drive system incorporating rotor shorting rings is evaluated, and experimental results show the effectiveness of the technique.

-The current study presents the design and performance of a novel 4/2 switched reluctance motor (SRM) for a high-speed air blower. With a comparative study of some rotor structures for a high-speed drive, a stepper-type rotor is optimized to produce a continuous torque and a low torque ripple. Rotor pole arc is modified to have a wide continuous output torque region, and air gap is determined to develop less torque ripple. The rotor radius is determined to reduce torque ripple with a reiterative FEM analysis. The designed rotor has three regions: short uniform, long uniform, and nonuniform air-gap region. The positive torque region is wider than a conventional 4/2 SRM without any torque dead zone. A prototype is tested and the efficiency is up to 72[%] at 30,000[rpm], 600 [w] output.
