Effects of Negative Sequence Voltage Subharmonics on Cage Induction Motors
Energies, 2022 In some power systems, voltage waveforms contain, apart from harmonics, interharmonics and subharmonics that are components of frequency less than or not an integer multiple of the fundamental frequency.

High-Power Induction Motors Supplied with Voltage Containing Subharmonics
Energies, 2020 In some power networks, components of frequency less than the frequency of the fundamental voltage harmonic called subharmonics or subsynchronous interharmonics occur.

Induction Motors Under Voltage Unbalance Combined with Voltage Subharmonics
EnergiesIn power systems, various power quality disturbances are present, including voltage deviation, voltage unbalance, and voltage waveform distortions. Voltage waveform distortions are usually identified with harmonics, but in some systems, subharmonics ...

Energies, 2023 In some power systems, the voltage waveform contains frequency components less than fundamental, called subharmonics or subsynchronous interharmonics. Voltage subharmonics can be both positive- and negative-sequence, independent of their frequency (order)

Frequency jumps and subharmonic components in calls of female Odorrana tormota differentially affect the vocal behaviors of male frogs [PDF]
Frontiers in Zoology, 2023 Studies have demonstrated that the sounds of animals from many taxa with nonlinear phenomena (NLP)—caused by nonlinear characteristics of vocal organ dynamics that lead to nonlinear vocal phenomena—can influence the behavior of receivers.

Use of Subharmonics of Base Frequencies in the CSRMT Method with Loop Sources
J, 2023 In the controlled source radiomagnetotelluric (CSRMT) sounding method, a horizontal magnetic dipole, HMD (vertical loop) or a horizontal electric dipole, and HED (grounded line) are used as sources.

Single-Phase Induction Motor Under Voltage Fluctuations
Scientific Journal of Gdynia Maritime University, 2022 Some of the most common power quality disturbances are voltage fluctuations. They are interconnected with the presence of voltage subharmonics and interharmonics.

Influence of Voltage Subharmonics on Line Start Permanent Magnet Synchronous Motor
IEEE Access, 2021 A particularly promising industrial prime mover is a line start permanent magnet synchronous motor (LSPMSM). LSPMSMs, just as other energy receivers, are exposed to the noxious impact of various power quality disturbances.

Energies, 2023 In modern power systems, interharmonics have emerged as noninteger frequency components that appear in current or voltage signals. Double-stage AC-DC-AC converters have been identified as a primary source of interharmonics.
