The need for more efficient and renewable means of transport makes the development of
hybrid electric vehicles (HEVs) an important topic for both automobile manufacturers and …

This paper reviews the current state of the art of condition monitoring and fault diagnosis
techniques for permanent magnet (PM) machines. It also takes into account the past …

The neglection of thermal-mechanical interaction of the high-speed motorized spindle
system may lead to modeling errors of thermal and dynamic characteristics. In this work, the …

Increasing the efficiency and sustainability of transportation is a key topic for both
automakers and academic researchers. The noise, vibration, and harshness (NVH) of …

Direct drive permanent magnet machines used in renewables typically have high numbers
of poles leading to low speeds. This poses a challenge for detection of faults during …

Partial demagnetization is a condition that may occur in Permanent Magnet machines due to
overloading or thermal stress. Whenthis happens, the magnetic field locally weakens …

This paper proposes a novel algorithm which made it feasible to predict the harmonic fault
signatures under dynamic eccentricity in Permanent-Magnet synchronous machines with …

In large induction machines (such as large cage induction motor pumps in the petrochemical
industry and cage-or wound-rotor induction generators in wind turbines), reliability and …

Eccentricity fault with 10% severity is probably the only existing fault in a brand new healthy
electrical machine that is acceptable as a manufacturing tolerance. This fault can be …

In this article, a novel method to detect the partial demagnetization in air-cored permanent-
magnet axial-flux generators is proposed. Its principle is to monitor a speed-normalized fault …
