“…In this fiercely competitive market, success hinges largely on addressing dynamic concerns like noise, vibration, and wiring harnesses. Regrettably, manufacturers have consistently encountered difficulties in finding effective solutions to noise-related problems [13]. This study would be helpful for those to establish an efficient and effective procedure for noise source identification [14].…”

The energy spectrum measurements in noise, vibration, and harness analysis with power spectrum response is a very ancient concept. The work and energy approaches for analyzing Noise, Vibration, and Harmonics (NVH) features are increasing rapidly in recent years. The primary focus is on evaluating imparted energy due to the NVH using an FFT spectrum against the input energy in motors. The simulation depicts the input energy spectra of the kinetic energy, absorbed energy, and dissipated energy very clearly. Earlier the smoothed Fourier amplitude spectrum approach was used for plotting the energy dissipation due to the NVH effect. However, most of the part of accountable energy goes to waste with noise, vibration, and harmonics generated due to harness in motor design. This experiment is conducted in support of Sir Nikola Tesla’s statement “If you wish to understand the universe think in terms of energy, frequency, and vibration”. The ripples an induced in phase current because of the step change of the speed. The predominant frequency in phase current waveform creates the collapsing vibratory waves that create the sound. Sound frequencies above 20 dB are considered unwanted sound known as noise. The energy level variation with NVH influence in BLDCM is measurable for its performance analysis. This research can be further enhanced by designing NVH-free BLDC motors.

“…Experimental Analysis of Vibration and Noise: Experimental analysis of vibration and acoustic noise in BLDC motors has been carried out using digital pulse width modulation (PWM) based control techniques [11]. Electronically commutated switches for rotor position detection have been used for motor speed control [12]. Fault isolation, based on fault signature tables, has been tested under noisy motor conditions [13].…”

This research paper focuses on the vital role of Brushless Direct Current (BLDC) motors in hybrid vehicle propulsion due to their efficiency and compact design. The primary objective is to evaluate BLDC motor performance within a vehicle chassis, with a specific focus on vibration characteristics. An innovative rotational tracker program is introduced to identify rotating machinery faults efficiently, reducing computational costs and aiding machinery selection for specific applications. The research involves comparing vibration characteristics of BLDC and stepper motors, using a 4kW BLDC motor to measure displacements along the X, Y, and Z axes within specified RPM and torque ranges while monitoring current variations during chassis installation. Findings emphasize the significance of proper motor installation in hybrid vehicle design to mitigate increased vibration levels. This study has implications for motor manufacturers and vehicle designers, underlining the importance of considering vibration performance during motor installation. It concludes by suggesting further research on broader RPM range BLDC motors and on-road measurements to advance understanding in the context of hybrid vehicle propulsion. In summary, this research explores the connection between BLDC motors, vibration characteristics, and their impact on vehicle performance, with significant implications for the automotive industry.
