In many direct-drive applications such as servo system, wind power generation, etc., it is desirable to use motors having a high torque density at a low rotation speed without reduction gears for the improvement of noises, reliability and maintenance.
A method to extract terahertz radiation from surface plasmon polaritons excited in the surface of a uniform graphene structure by an electron beam is presented. A sidewall configuration is proposed to lift the surface plasmon mode to be close to the light line, so that some of its harmonics have chances to go above the light line and become radiative. The harmonics are considered to be excited by...
Eddy current loss is a typical problem in permanent magnet machines especially in machines equipped with fractional-slot concentrated windings. PM segmentation which cut the circulating path of eddy current in radial flux PM machines have been widely studied in literature to reduce this loss. Both circumferential and axial magnet segmentations were evaluated by an analytical method concerning the...
Power hardware-in-the-loop (PHIL) is an important tool for testing and verifying various aspects of systems level research. It provides a realistic assessment of how a device will interact under various conditions and environments, allowing the testing process to truly vet the apparatuses before full scale deployment. Crucial to the PHIL concept, is the hardware-in-the-loop interface. Interfaces must...
Based on the simple hinge crack model, the dynamic equation of a rotor containing transverse crack and initial deflection is modelled in dimensionless form, which can be applied to the vibration analysis of cracked rotor with different parameters at stationary, transient and nonlinear state. By analytical solution, the frequency components of the cracked rotor with initial deflection are analyzed,...
