An eccentric harmonic magnetic gear (EHMG) is better suited for situations requiring larger transmission ratios than magnetic-field-modulated gears. In the meantime, to increase torque density even further, a new structure EHMGs presented in this paper. The stator’s permanent magnets (PMs) are irregularly distributed, while rotor’s PMs applied fan-shaped structure. Moreover, Halbach array adopt...
We present two fiberized vector magnetic-field sensors, based on nitrogen-vacancy (NV) centers in diamond. The sensors feature sub-nT/ Hz magnetic sensitivity. use commercially available components to ...
The demand for electric bikes has been increasing in recent years, and so their drive, which requires a high power-to-weight ratio or power density. An axial-flux permanent magnet motor with Halbach-array is an excellent choice bike drives thanks to its known characteristics of density, reliability, efficiency. However, because machine topology not common, the manufacturing process can be chall...
This paper describes work on alternative technologies associated with an urban maglev system that employs Halbach arrays of permanent magnets onboard a moving vehicle to induce levitating currents in a stationary “track”. A laminated structure, composed of stacks of thin conducting sheets, has several advantages over a litz-cable ladder as the track. Modeling and experimental results for the la...
Delivery of cells into tubular tissue constructs with large diameters poses significant spatial and temporal challenges. This study describes preliminary findings for a novel process for rapid and uniform seeding of cells onto the luminal surface of large tubular constructs. Fibroblasts, tagged with superparamagnetic iron oxide nanoparticles (SPION), were directed onto the luminal surface of tu...
