Sensorless Control of the Permanent Magnet Synchronous Motor [PDF]
This paper describes the study and experimental verification of sensorless control of permanent magnet synchronous motors with a high precision drive using two novel estimation methods. All the studies of the modified Luenberger observer, reference model, and unscented Kalman filter are presented with algorithm details.

Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]
The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

Analysis of Copper Loss of Permanent Magnet Synchronous Motor With Formed Transposition Winding
In recent years, the hairpin winding flat wire motor has received more and more attention because of its high power density and high torque, but the problem of increased AC copper loss caused by the increase of its wire diameter has restricted the use of

PERMANENT MAGNET SYNCHRONOUS MOTOR
Synchronous machine (CM) is an alternating current electric machine whose rotor speed is directed in the same direction as the speed of the electromagnetic field. In a synchronous generator with permanent magnets on the rotor, there is no excitation winding, and the magnetic flux of excitation is created due to permanent magnets, not coils.

Topological optimization of the rotors of permanent magnet synchronous motors [PDF]
Permanent magnet synchronous motors are increasingly used in the oil industry. These motors need to be made more energy efficient. To do this, it is necessary to optimize the rotor of a synchronous motor by changing the design through topological ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
