“…Multiphase motors have been widely used in air-craft drives, locomotive traction, electric ship propulsion and high-power industrial applications [1][2]. As the number of phases increases, the required stator current amplitude can be reduced without changing phase voltages and output power [3][4].…”

“…Several model-based methods have been presented in [12]- [16]. When an open-phase fault appears, the conventional Park transformation matrix should be reconstructed because of the asymmetry in the stator phase currents.…”

“…The magnitude of the pulsating torque depends on the difference between the αβ-subspace current components [14]. By using the same modeling approach, the pulsating torque components are eliminated for a five-phase and nine-phase motor, respectively [15][16]. However, for the multiphase concentrated-full-pitch winding IM, the reconstruction of the Park transformation matrix cannot provide a diagonal mutual inductance matrix (Lsr) in the αβ reference frame.…”

“…However, for the multiphase concentrated-full-pitch winding IM, the reconstruction of the Park transformation matrix cannot provide a diagonal mutual inductance matrix (Lsr) in the αβ reference frame. Hence the torque cannot be decoupled, and the torque ripple still exists during post-fault operation under single-phase fault [15][16]. The model-based methods can only be used in the motor with sinusoidal distributed winding structure, and the coupling between spatial harmonic fields limits its use in the concentrated-full-pitch winding IM.…”

“…The usage of a nine-phase induction motor (IM) to power the electric powertrain is allocated in the rear axle. Multi-phase motors (more than three) have advantages in electric propulsion applications such as reliability, third harmonic that can be used to increase the torque, voltage level reduction, and electronic pole changing [23][24][25][26][27][28][29][30][31]. For EV and HEV, which have external recharge aid, called vehicles plug-in, the nine-phase IM can be used as part of onboard integrated recharger for the battery system [32].…”

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.

Multiphase induction machines are getting more attention in industry and academia because of their advantages and need for electric vehicles as well as ship propulsion. In this case, more number of power electronics devices are required due to higher number of phases. Moreover, in comparison with electromechanical systems, the probability of failure in power electronic inverter switches will be high. A fault in a semiconductor switch, without any proper alleviating methods, may result in the failure of the entire drive. To improve the reliability of induction motor drives (IMD), there is a necessity to enhance the postfault operation of the inverters. In this article, the proposed nine‐phase IMD incorporates simple mathematical equations and less circuit reconfigurations to work under conditions of open‐switch fault in either a single switch or the inverter's entire leg. This enables the drive to achieve balanced steady‐state operation with minimal deration in output power/torque under the fault conditions. In addition, alternative operational technique, which modulates the healthy phases of fault phase group with 50% duty ratio and minimal circuit reconfiguration, is discussed in this article. Moreover, all possible fault conditions and associated reconfiguration details of the drive are described in detail. To validate the proposed concepts, finite element method analysis is performed using ANSYS Maxwell, and experimentation is performed in the laboratory for both normal and fault conditions on nine‐phase IMD.
