The influence of the spiral angle of SMMSM, number of magnetic bar, thickness of magnetic bar, and thickness of air gap on the torque are explored, and key structural parameters are selected to design and manufacture the prototype. A static and dynamic experimental platform is built, and the experiment show that the maximum output torque of the SMMSM can reach 1.185 N m at a displacement of 1 mm, and the step response time is 27.5 ms, which are substantially superior to the existing maglev couplings.

To this end, a self-priming performance test apparatus, appropriate for high suction range pumps, was developed. By monitoring the fluctuations in inlet vacuum levels and external characteristic parameters throughout the self-priming process, experiments were conducted under five distinct conditions: inlet vacuum levels of 0.07 MPa, and rotational speeds of 200 rpm, 250 rpm, 300 rpm, 350 rpm, and 400 rpm. The results obtained offer insights into the alterations in external characteristic parameters during the self-priming process. Based on the phase state of the suction medium, the self-priming process can be categorized into three stages: the inspiratory stage, the gas-liquid mixed transport stage, and the normal operation stage. The experimental findings indicate that the operating speed significantly influences the self-priming process, primarily reflected in the changes in external parameters. The response of shaft power to the inlet vacuum degree is more pronounced at higher speeds. From the perspective of flow rate variation, the rate of flow change is faster at higher speeds, and the conveying efficiency is higher during the gas-liquid mixed transport stage. Analyzing the self-priming performance reveals that speed has a greater impact on the inspiratory stage of the self-priming process and a lesser impact on the gas-liquid mixed transport stage.
