Numerical-field analysis of active and reactive winding parameters and mechanical characteristics of a squirrel-cage induction motor

Electrical engineering & Electromechanics, 2023
Introduction. The active and reactive (inductive) winding resistances of three-phase asynchronous motors (IM) are investigated. These important parameters are determined during design and are the basis for calculating a number of energy parameters and ...

Controlled rotary motion of light-driven molecular motors assembled on a gold film [PDF]

, 2010
Using circular dichroism (CD) spectroscopy, we show that light-driven rotary molecular motors based on overcrowded alkenes can function in a self-assembled monolayer on semi-transparent gold films.

Composite Dipolar Recoupling: Anisotropy Compensated Coherence Transfer in Solid-State NMR [PDF]

, 2006
The efficiency of dipole-dipole coupling driven coherence transfer experiments in solid-state NMR spectroscopy of powder samples is limited by dispersion of the orientation of the internuclear vectors relative to the external magnetic field.
