This paper analyzes the performance of Kalman filter-based estimators for robust filtering and rotor asymmetry detection in wound rotor induction machines (WRIMs) using real-time data. Filter models were designed based on an extended model of WRIMs.

Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]
For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.

Analysis of cogging torque in brushless machines having nonuniformly distributed stator slots and stepped rotor magnets [PDF]
A simple analytical technique is proposed for synthesizing the cogging torque waveform of a permanent magnet brushless machine from the cogging torque waveform that is associated with a single stator slot.

Flux observer algorithms for direct torque control of brushless doubly-fed reluctance machines [PDF]
Direct Torque Control (DTC) has been extensively researched and applied to most AC machines during the last two decades. Its first application to the Brushless Doubly-Fed Reluctance Machine (BDFRM), a promising cost-effective candidate for drive and ...

Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Electroactive Liquid Crystal Elastomers as Soft Actuators
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Novel Winding Design and Analysis of Brushless Wound Rotor Synchronous Machines
Synchronous machines are electric machines characterised by a rotating speed proportional to the AC supply and are independent of load. Traditional permanent magnet synchronous machines utilise rare earth minerals for rotor flux generation, posing ...
