“…The mode orders and angular frequencies can be computed from the orders and angular frequencies of the air-gap flux-density harmonic components, . In [2], the frequency spectra are calculated directly from (1). However, although it is entirely general, it gives little insight regarding the dominant components and the associated vibration modes.…”

“…As an approximation, may be deduced from the product of the airgap mmf, , and the air-gap permeance, , i.e., (2) The MMF wave in a PWM-inverter-fed three-phase induction motor can be obtained in a similar way to the machines fed from sinusoidal power supply [10] and can be expressed as (3) where number of pole pairs; fundamental angular frequency of the supply; angular frequency of the th current harmonic. The first term is the fundamental air-gap MMF wave produced by the fundamental current, and the second term represents firstorder MMF harmonics due to current harmonics.…”

“…T HE acoustic noise radiated by induction machines increases when they are operated from nonsinusoidal power supplies, such as quasi-square waveform and pulsewidth modulation (PWM) converters [1], [2]. This can be of considerable significance in certain applications, for example, when they are employed as traction machines in the drivetrain of electric vehicles.…”

Abstract-This paper investigates the acoustic noise radiated from two nominally identical induction motors when fed from sinusoidal, and asymmetric regular sampling subharmonic and space-vector pulsewidth modulation (PWM) converters. The theory for analyzing the noise spectrum is developed further to account for the interaction between the motor and the drive. It is shown that manufacturing tolerances can result in significant differences in the noise level emitted from nominally identical motors, and that mechanical resonances can result in extremely high noise emissions. Such resonances can be induced by stator and rotor slot air-gap field harmonics due to the fundamental component of current, and by the interaction between the airgap field harmonics produced by the fundamental and the PWM harmonic currents. The significance of the effect of PWM strategy on the noise is closely related to the mechanical resonance with vibration mode order zero, while the PWM strategy will be critical only if the dominant cause of the emitted noise is the interaction of the fundamental air-gap field and PWM harmonics.

“…Electromagnetic noise is the general component of the acoustic noise and vibrations, which results as the action of the magnetic (excited) forces in the airgap. Additional magnetic noise from AC motors driven by PWM inverters is caused by the high-frequency harmonics contained in the output waveforms [4], [5].…”

Abstract-This paper presents an iterative approach to identification of sources and characteristics of rotor and airgap eccentricity and, consequently, unbalanced magnetic pull (UMP) in asynchronous motors. The presented method is based on the number of mathematical modeling techniques, namely: finite elements method (FEM), Lagrangian dynamics and optimal estimation in combination with experimental measurements.
