Design of a spherical vehicle with flywheel momentum storage for high torque capabilities
… completed and indicates significantly increased torque capabilities for ascending steep inclines and stairs. A fully functional prototype is built and testing is ongoing to verify its capabilities.

Induction Machine Performance Improvements: Design-Oriented Approaches
… and FEA. This machine has limited nominal torque capabilities due to saturated stator and rotor teeth, discovered neither by the design software (analytically based) nor FEA. The 3-D MEC model, about a magnitude smaller in complexity and size than the FEA model, more accurately estimates …

High performance induction machine control: Methods, limits and solutions
… high speed DTC operation, including excessive torque ripple and diminished torque capability of the drive method. Asymptotic-input-output-decoupling is proposed to improve this erratic DTC performance. The results show that asymptotic decoupling compensates for erratic DTC performance with …

Some aspects of wind tunnel magnetic suspension systems with special application at large physical scales
… thesis.<br/>A powerful method of magnetic roll torque generation is essential for any LMSBS. Two variants of the new Spanwise Magnet scheme are studied herein. Spanwise Permanent Magnets are shown to be a practical method and are experimentally demonstrated using the Southampton University MSBS, …

A framework for dynamic characterization and short-term thermal capability assessment of electric machines and inverters in motor drives
… to illuminate the full extent of their peak capabilities and control strategies to safely attain peak torque. Vector-controlled induction machine torque capabilities are assessed and limiting factors are investigated. Static and dynamic thermal characterizations are carried out through …

Screw piles as offshore foundations : Numerical and physical modelling
… in predicting the required installation torque and the capacity in different soil types and stress histories. For example, without the ability to accurately predict installation torque, it is difficult to design screw piles for offshore use or develop appropriate installation plant with …
