Abstract To facilitate the regulation of the air‐gap magnetic field of permanent magnet synchronous machines, a novel topology of a high‐speed hybrid excitation synchronous machine (HESM) was presented. The electromagnetic performance of the prop

Spatially Offset Raman Spectroscopy (SORS) has extensively been studied as a non-invasive technique that can detect the internal composition below the surface of turbid samples. A critical application of SORS is to identify unknown materials behind a

Over the past few years, the utilization of spatially offset Raman spectroscopy (SORS) has significantly evolved in its ability to analyze layered turbid materials non-invasively. It is well known that SORS can effectively detect the deeper layer in

In this paper, an analytical model is established to predict the performance of a novel permanent magnet (PM) biased heteropolar radial magnetic bearing, which has some merits of volume and axial length. Due to the symmetrical structure, the periodic

Effects of shaft shape errors are studied on dynamic characteristics of a rotor-bearing system. Stability characteristics of the cylindrical journal bearing are studied. It is shown that the rotating speed at which the oil whip occurs increases when

The transient model of a rotor-bearing system in marine thrusters was established, including 5-DOF model of the rotor and 3-DOF model of the rubber-supported water lubricated thrust bearing. In the model, mixed-TEHD was coupled and the damping of the

Permanent magnet-biased magnetic bearings (PBMBs) are widely used in flywheel energy storage systems because of their comprehensive advantage in power loss and controllability. However, there is a nonlinear relationship between magnetic force, contro

This paper presents an analytical model based on the subdomain method and conformal mapping method for predicting the performance of the permanent magnet (PM) biased homo-polar radial magnetic bearing (HRMB). Due to the homo-polar PM flux field of HR

This paper proposes a permanent magnet (PM) biased axial magnetic bearing (MB) with multiple air gaps. However, the inherent complex structure makes finite-element analysis (FEA) very time-consuming. For the sake of simplifying the analysis, an equiv

The rotor unbalance will excite fundamental frequency vibration in the flywheel energy storage system. To reduce the cost and improve the reliability of the system, the vibration signals can be used for speed estimation and phase synchronization. For
