Modeling of cross-coupling magnetic saturation in signal-injection-based sensorless control of permanent-magnet brushless AC motors [PDF]
An improved brushless AC motor model is proposed for use in signal-injection-based sensorless control schemes by accounting for cross-coupling magnetic saturation between the - and -axes.

Sensorless Operation of Brushless DC Motor Drive using Back EMF Technique
The Brushless Direct Current (BLDC) motors are one of the motor types that is gaining rapid popularity. Its major appliances include refrigerators, washing machines, vacuum cleaners, freezers, etc. As the name implies, BLDC motors do not use brushes for commutation; instead, they are electronically commutated.

Background Thermographic‐infrared changes during osteotomy surgery depend on the type of motor used, size, and system of the dental implant. This study undertakes the evaluation of these thermal variations for successful optimization of dependent surgical procedures while aiming toward reduced thermal damage to the bone tissue.

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

To overcome the porosity‐conductivity trade‐off in conductive porous membranes, a conductive nanofibrous membrane bridged by self‐assembled PPy nanowires is constructed, integrating multiscale porosity with continuous electron pathways. This material‐structure‐function strategy achieves low‐resistance and high‐efficiency filtration combined with ...

The research introduces a three‐phase electrostatic (ES) clutch with variable mechanical impedance control, specifically designed to enable continuous and precise friction modulation, thereby reducing both force degradation and oscillatory motion. This method effectively resolves conventional ES clutch issues, such as residual charge accumulation and ...
