Chevrolet Bolt EV Drivetrain Teardown Data and FEA Motor Model

For this dataset, a comprehensive teardown study was conducted on the drive unit of the 2017 Chevrolet Bolt. The study involved a complete teardown of the drive unit, including the 150 kW traction machine and gearbox. Each component was meticulously measured for size and weight. An electromagnetic finite element analysis (FEA) model was developed using measured rotor, stator, and magnet geometries to validate motor performance against published data. Simulation results showed discrepancies of less than 1.6% for torque and 3% for torque ripple.
