Abstract
Noise research system for electric vehicle motor is established based on minimum output energy during the array signal processing. We can obtain the distribution of noise through the system. The experiment is carried when the motor is in the background condition and at low speed and torque conditions. The noise field distributions are more prominent with the principle of minimum output energy than those of channel weighting factor with 1. Combining motor structures, we can further determine the location of the main noise. Test results are the same with the actual situation.
