Comparison of AC Motors to an Ideal Machine Part I-Conventional AC Machines

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
While comparison of the torque produced by AC machines of a given topology is, today, a standard feature of the machine design process, comparison of machines from different families of machine types is less frequently undertaken. This two part paper compares the torque performance of 6 types of AC machines based on the same current level, flux level ...

Machine learning predicts risk in ACS

Nature Reviews Cardiology, 2021
A new machine learning risk-stratification model accurately predicts the 1-year risk of ischaemic and major bleeding events in patients with an acute coronary syndrome and might be useful to guide clinical decision-making and optimize the quality of care of these patients.

Comparison of AC Motors to an Ideal Machine Part II—Non-Sinusoidal AC Machines

IEEE Transactions on Industry Applications, 2019
This two-part article compares the torque performance of 12 types of ac machines based on the same surface current density, tooth flux density, and rotor dimensions. Part II examines the torque capability of machines more recently developed which utilize the wave shaping capability of a solid-state frequency inverter.

Algebraic synthesis and analysis of windings for AC machines

e & i Elektrotechnik und Informationstechnik, 2021
This paper presents an important method for the algebraic synthesis of the winding layout of AC machines. It applies in general to integral-slot and fractional-slot windings, including non-overlapping windings, so it can be claimed to unify the synthesis task. Moreover, it results in the highest possible winding factor at the working harmonic.

CONTROL OF AC-MACHINES WITH THE HELP OF MICROELECTRONICS

IFAC Proceedings Volumes, 1983
Abstract AC-machines, in particular induction motors, are of simple mechanical construction but have a nonlinear, highly interacting multivariable control structure. This, in combination with the short time scale involved, has made it difficult in the past to design controlled AC-drives with high dynamic performance.
