Multi-Harmonic Currents Control Strategy for Five-Phase Permanent Magnet Machine With Non-Sinusoidal Back-EMF

IEEE Access
This paper describes an optimal torque per peak current control method for a five-phase permanent magnet (PM) machine considering both $3^{\mathrm {rd}}$ and $5^{\mathrm {th}}$ harmonic currents.

Open Fault Detection in Variable Phase-Pole Machines Based on Harmonic Plane Decomposition

IEEE Transactions on Power Electronics
Multiphase electrical machines are inherently fault tolerant due to the higher number of phases. An important step in achieving a fault tolerant control is the ability to detect and identify the fault. In variable phase-pole drives, which are a class of multiphase machines that change the number of pole pairs during real-time operation, there are ...

Open-Phase Fault-Tolerant Pole Transition Control of an Asynchronous Variable-Pole Machine Using Harmonic Plane Decomposition

IEEE Journal of Emerging and Selected Topics in Power Electronics
Automotive applications are revisiting the use of induction machines as magnet-free propulsive solutions due to their intrinsic robustness and reliability. Special multiphase configurations are under investigation to reduce the losses further and fulfill the stringent energy-efficiency and compactness requirements of the automotive industry.

CASPT2 Study of the Unimolecular Reactions of Nitromethane—A Look at the Roaming Reactions in the Decomposition of Nitromethane: An Exergonic Route at High Temperatures

Reactions
In this work, we studied the main decomposition reactions on the ground state of nitromethane (CH3NO2) with the CASPT2 approach. The energetics of the main elementary reactions of the title molecule have been analyzed on the basis of Gibbs free energies ...
