NVH testing is an inseparable part of the automotive product and component design and development process. With the global shift towards hybrid and electric vehicles, it is important to understand the NVH characteristics of electric power trains. Brushless DC (BLDC) motors are the most commonly used electric vehicle motors but one of their major drawbacks is the acoustic noise and vibration caused by torque ripples. This project investigates the source of noise and vibration in an 800 W BLDC hub Motor used in an Electric Scooter. A 3D model has been generated approximately to the real life model then Modal analysis using FEM is performed using Ansys to determine the natural frequency of the vibrating parts of the motor in static conditions. The results of these simulations are to be compared and validated experimentally. The dynamic condition frequencies are also determined. It also deals experimental Noise Analysis. |
