Detection of inter-turn faults in multi-phase ferrite-PM assisted synchronous reluctance machine [PDF]

open access: yes, 2019
Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected in a timely manner, since they can quickly progress into more severe short-circuit

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Electric motor modeling, analysis, and design for E-mobility applications: A state of the art

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy
The transportation sector has steadily shifted towards Electro-Mobility (E-Mobility) to achieve net-zero carbon emissions. One of the most important components of E-mobility is the electric motor, which must be designed for high torque, a wide speed ...

Development of sensorless vector control system for permanent magnet synchronous motor in Matlab Simulink

open access: yesЗаписки Горного института, 2018
In last 20 years segment of electric drives with permanent magnet synchronous motors has increased. This type of motors has better technical characteristics compared to induction motors, but has problems in actual implementation, one of which is the ...

A quantitative comparison between BLDC, PMSM, brushed DC and stepping motor technologies [PDF]

open access: yes, 2016
Brushless DC machines (BLDC), Permanent Magnet Synchronous Machines (PMSM), Stepping Motors and Brushed DC machines (BDC) usage is ubiquitous in the power range below 1,5kW. There is a lot of common knowledge on these technologies.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Traction Synchronous Motors with Rotor Field Winding: A Literature Review

open access: yesWorld Electric Vehicle Journal
Synchronous motors with a field winding in the rotor, known as wound-rotor synchronous motors (WRSMs) or electrically excited synchronous motors (EESMs), are claimed to be a good alternative to induction motors and even permanent-magnet synchronous ...

Online optimal flux-weakening control of permanent-magnet brushless AC drives [PDF]

open access: yes, 2000
An enhanced online optimal control strategy, which maximizes the flux-weakening performance of a brushless AC motor, is described, and applied to motors having different rotor topologies: interior (radial or circumferential), inset, and surface-mounted ...
