Optimization and Experimental Validation of Amorphous Alloy High-Speed Asynchronous Motor for Simultaneous Reduction on Core and Copper Losses

open access: yesIEEE Access, 2023
Amorphous alloy has been proposed to replace silicon steel as the stator core material of high-speed asynchronous motors so as to reduce their core losses. However, it is found that this is at the expense of increasing the copper loss.

Discriminative methods for classification of asynchronous imaginary motor tasks from EEG data [PDF]

open access: yes, 2013
In this work, two methods based on statistical models that take into account the temporal changes in the electroencephalographic (EEG) signal are proposed for asynchronous brain-computer interfaces (BCI) based on imaginary motor tasks. Unlike the current

Methodology for Asynchronous Motor Impedance Measurement by Using Higher Order Harmonics

open access: yesEnergies, 2020
The control methods of asynchronous motors have changed during past decades. In the past, asynchronous motors were connected to grid directly. Later, thyristors as switching element-based frequency converters for asynchronous motors have appeared. Today,
