Correlating power measurements with electro motor vibration data
The challenge
The rapid evolution of electric vehicles has created new design, testing and measuring challenges for engineers. One of the most pressing needs has been in the area of vibration analysis. Engineers have struggled in particular to separate the harmonics coming from the slotting effect (i.e. air gap permeance fluctuations due to rotor and stator slots), and harmonics coming from the inverter.
Before 2011, asynchronous motor energy losses were assumed to be 0.5%.
