The large permanent magnet synchronous machine(PMSM) usually adopts modularity technique to facilitate the manufacture and maintenance. In order to avoid the contact of adjacent coils between modules, a novel unwinding stator module combined permanent magnet synchronous machine (SMCPMSM) is proposed, in which each modular can operate independently. The number of input modules can be flexibly selected according to the torque requirement in the SMCPMSM of mill wrapping around to realize the optimal control of mill system efficiency. In this paper, the unwinding block method and its mathematical model of the SMCPMSM are described. The electromagnetic performance of the SMCPMSM and the operation performance of different power supply modules (PSMs) are analyzed, the radial force and electromagnetic vibration of the PSM in asymmetric operation is studied, which provides a reasonable basis for the part of PSM operation of the SMCPMSM in accordance with torque requirements.

“…In [18]- [20], the SVPWM with modified switching sequence is used to reduce the noise in the range of human hearing, but the high-frequency harmonics cannot be eliminated. In application of twosegment three-phase PMSM, the interleaved technique with magnetically coupled inductors [21] and phase shift PWM technology [22], [23], are proposed, but two inverters are necessary. Additionally, some strategies involving carrier are reported to reduce high-frequency harmonics.…”

The underwater noise can be caused by the radial electromagnetic vibration of permanent magnet synchronous motor (PMSM) for electric propulsion. The difficulty in decreasing the underwater noise is not only the high-frequency but also low-frequency vibration reduction. This paper proposes a novel random asymmetric carrier pulse width modulation (RACPWM) method for PMSM vibration reduction in the whole frequency range. Instead of the conventional symmetric triangular carrier PWM, the asymmetric carrier PWM (ACPWM) is used to decrease the low-frequency phase current harmonics and the associated low-frequency vibration. Meanwhile, in order to suppress the high-frequency vibration, the RACPWM control based on the amplitude randomization of the sawtooth carrier is further presented to reduce the high-frequency phase current harmonics. Moreover, the RACPWM is equivalent to the random slope ACPWM in view of the output signals. Furthermore, without the need of any additional circuits in the drive, the presented method is simple to implement by software. Simulation and experimental results show that the proposed RACPWM method can effectively reduce both the low-frequency and the high-frequency vibration.

“…As a popular motor choice, permanent magnet synchronous motor (PMSM) has the advantages of high torque-current ratio, high power density, and high efficiency. Multiphase PMSM gets rid of the restrictions on power electronic devices in high-power situations and has a smoother torque waveform [1][2][3][4]. So, it becomes a research hotspot and can be especially suitable for applications such as electric vehicles, railways and aircraft propulsion [5].…”

Dual three-phase permanent magnet synchronous motor (PMSM) is a major area of interest within the field of motors since it inherits the advantages of both the PMSM and multiphase machines. While dual three-phase PMSM (DTP-PMSM) system has a more severe carrier frequency harmonic problem due to the low impedance in the harmonic subspace, which will not only decrease the efficiency but also produce the high-frequency audible noise. This study proposes an improved space vector pulse-width modulation (SVPWM) strategy by changing the sequence of the pulse-width modulation wave. The improved SVPWM strategy with a 10 kHz carrier frequency has the same effect as the conventional SVPWM with a 20 kHz carrier frequency, which will significantly decrease the switching loss, lead to lower size of inductance, capacitance and eliminate the high-frequency audible noise. Three existing mainstream SVPWM strategies in DTP-PMSM system are introduced and the proposed strategy can be used in them without affecting their original advantages. The switching times are also minimised to reduce the switching loss. The theoretical derivation is proposed to prove the harmonic suppression ability of the proposed SVPWM and the implementation procedure is given then. The simulation and experimental results proved the effectiveness of the strategy.
