“…The nine‐phase IM used in this paper was designed and a built‐in partnership between UFMG and Werner Eggon Geraldo (WEG) corporation to support Ph.D. and M.Sc. research projects [23, 24, 31, 33, 34]. Owing to this initial application, this electric motor was designed to operate at a high‐rated speed with a frequency of 240 Hz.…”

“…These advantages are better discussed below: Reliability : If one or few phases of a motor or converter stop working, it would be desirable that the driver would be able to take the vehicle, at least, to the closest parking area. Nine‐phase motors are able to work in this condition [23, 26, 33, 34]. Torque increase : It is possible to improve the torque capability by injection of third harmonic currents in nine‐phase IM without neutral conductor connection [23, 26].…”

This study investigates the usage of a nine-phase induction motor (IM) in internal combustion engine vehicle hybridisation. Aiming to minimise structural changes, the parallel-through-the-road (TTR) hybrid architecture was chosen. First, a real vehicle was experimented on the mobility technology centre Federal University of Minas Gerais (CTM-Universidade Federal de Minas Gerais (UFMG) laboratory) to get its characteristics. After that, this technical information was used to model and simulate on the software advanced vehicle simulator (ADVISOR). The simulated model results were compared with the experimental tests results realised with the vehicle on the tests track and CTM-UFMG. Posteriorly, through a validated vehicle model, a drivetrain powered by a prototype of a nine-phase IM was integrated into the rear axle to do the hybridisation process simulation. To do that some structures modifications were necessary on ADVISOR since this tool does not include the parallel-TTR architecture. Vehicles modelled were simulated using the urban driving dynamometer schedules. Finally, the comparative analyses of simulation results show the improvements in fuel consumption, vehicle efficiency, emission gas, and the nine-phase motor operation in a hybrid TTR.

“…As with open-phase defectiveness, the drive should be controlled by the remaining healthy phases. The study of a short-circuit failure in a nine-phase SCIM drive is reported in [20]. Using a balanced short circuit following a short-circuit defect of the converter or the motor is recommended as a post-fault control approach [21].…”
