remarkably minimize the torque ripples for a surface-mounted permanent magnet …

To facilitate the active magnetic bearing (AMB) design and analysis, an accurate and fast
model that considers both rotor eccentricity and the saturation effect is necessary. In this …

In the presence of non-uniform loads, rotor misalignment emerges as a prevalent fault in
permanent magnet synchronous motors (PMSMs), leading to the manifestation of an axial …

Permanent magnet (PM) machine has received much attention recently. However,
unbalanced magnetic force (UMF) may occur in PM machines with some slot/pole number …

The distortion of air gap magnetic field caused by the rotor eccentricity contributes to the
electromechanical coupling vibration of the brushless DC (BLDC) permanent magnet in …

The effect of unbalanced magnetic pull (UMP) caused by air gap eccentricity on the vibration
of a permanent magnet synchronous motor (PMSM) is investigated. The force model is …

Air-gap eccentricity is one of the common faults of typical rotating machine, which results in a
dynamic instability state of multi-physical fields. To investigate the muti-physical instabilities …

The active removal of expired satellites on orbit is essential to ensure the safety of functional
spacecrafts on orbit. The high tumbling rates of the uncontrolled satellites hinder the direct …

In this article, the surface-mounted permanent magnet machine is regarded as a salient pole
reluctance machine to take into account the effect of stator teeth. The field modulation …
