The Design and Verification of 150[kW] Drive Unit for EV

In this paper, we summarize the finite element analysis results and experimental verification results of the electric motor of a 150 [kW] drive unit for electric vehicles. Analyze the no-load and load characteristics of electric motors and perform mechanical analysis at high speeds. To experimentally verify the drive unit, a coaxial reducer with the same motor output shaft and reducer output was designed and manufactured, and the experiment was conducted in accordance with the KS R 1203 standard. The design process of the drive unit for electric vehicles is verified through comparative analysis of analysis results and experimental results.
