“…Thus, the rotor side can resolve less space harmonics due to the Nyquist-Shannon sampling theorem, which is equivalent to less harmonic planes as these correspond to spatial harmonics. [12] also describes this phenomenon. In order to avoid aliasing, the rotor side Clarke transformation is adapted as in (2).…”

“…By setting the transformation angle to ϑ h̸ =p,k f in all non-excite harmonic planes, the pulsating current space-vector all align with the d-axis, enabling the control via a PIR-controller. (12) shows the time-discrete implementation of the PIR-controller. In this case, the PIR-controller is dynamically tuned to the stator current frequency, i.e., ω 0 = ω s .…”

A special subcategory of multiphase electrical machines are the so called variable phase-pole machines. They have the ability to electronically change the number of polepairs without any hardware reconfiguration. Moreover, they are inherently fault tolerant due to the higher number of independent windings. These two virtues offer new possibilities for a drivetrain with higher power density and a new level of reliability. This paper presents an adapted post-fault controller performing a pole transition with an open-phase fault. The drive changes the number of pole-pairs without loosing the torque during the transition and minimizes the stator copper losses simultaneously. The validity of the presented control is shown in simulations.

“…This approximation however neglects the uneven distribution of forces on the tooth heads, leading to non-negligible errors in the calculation of vibration and noise [121]. Concentrated moment can be applied to the centre of the tooth head to take into account the non-uniform distribution of forces [81], [123]. According to the sampling theorem [127] the spatial order is function of the number of stator teeth…”

This paper provides an overview of current Noise Vibration and Harshness (NVH) challenges for the design of Permanent Magnet Synchronous Motors (PMSMs) for automotive applications. Particular attention is devoted to analytical and numerical methods utilized in NVH modelling. Electromagnetic force computation, motor structural modelling and acoustic emission calculation are reviewed focusing on NVH emissions. The literature reveals, as expected, that analytical methods are simpler than numerical ones, and are usually employed during the preliminary design stage. Numerical methods are adopted in the detailed design stage as the computational cost increases. PMSMs are selected for high performance and high efficiency motor drives, they are widely adopted in the actual transition to vehicle electrification. The paper provides guidelines for facing NVH design issues of PMSMs.

“…Therefore, most of the design methods to suppress the electromagnetic vibration of PMSM are to preferentially reduce the amplitude of low order electromagnetic force harmonics. However, the effect of only reducing the low order electromagnetic force on suppressing electromagnetic vibration depends on the slot‐pole combination [14]. For fractional‐slot concentrated winding and integral‐slot winding PMSMs, the suppression of the low radial force cannot significantly reduce the electromagnetic vibration, especially when the PMSM is under light load [15].…”

A multi‐phase permanent magnet synchronous motor (PMSM) with fractional‐slot windings is proposed to reduce electromagnetic vibration and improve torque performance. Firstly, the analytical expression of electromagnetic force is derived, and the stator teeth modulation effect of electromagnetic force is introduced. The spatial order of the electromagnetic force and the stator teeth modulation are closely related to the slot‐pole combination of the PMSM. Then, three PMSMs with different slot‐pole combinations are presented, and they represent fractional‐slot concentrated winding, integral‐slot distributed winding and fractional‐slot distributed winding, respectively. Their torque performance and electromagnetic vibration performance are studied and compared considering stator teeth modulation. In addition, the multi‐phase winding technology is adopted to further improve the torque performance of the proposed PMSM. Finally, a 90s20p PMSM is manufactured, and the finite element method and experimental method are used to verify the proposed low vibration design method.
