| Summary: | This paper presents the world’s smallest two-phase flux-switching motor (FSM), featuring a four-pole stator and a two-pole rotor with a non-uniform air gap design. The FSM offers several advantages, including a compact size, simple structure, and ease of manufacturing, making it suitable for future micromachine applications. The motor has an outer stator diameter of 8 mm, an outer rotor diameter of 4 mm, and a stack length of 5 mm. This research employs a topological method and JMAG-Designer Ver.22.0 electromagnetic analysis software to enhance the rotor design for high output torque and low torque ripple. The final design achieves an average torque of 174 μN-m and a torque ripple of 40%, which is lower than those of any two-phase motor reported in the literature. The two-phase FSM has been fabricated, assembled, and tested to demonstrate its feasibility. |
