Dual Motor Drive System For Formula Sae Electric Race Car, Bryan D. Neill, Jackson T. Mcfaul, Cole T. Andrews, Isaiah D. Penzell

Mechanical Engineering

This paper serves as the Final Design Report (FDR) for the senior project developed by our team. This FDR builds on our CDR, in which the main deliverable was the detailed design of a planetary gearbox delivering a 5:1 reduction to be mated to an Emrax 188 motor. This planetary gearbox would allow for the possibility of implementing a dual-motor torque-vectoring rear-wheel-drive system in Cal Poly Racing’s electric FSAE car, which has demonstrated in simulation to yield significant performance gain over the current single motor/mechanical LSD system. As this project’s scope is purely mechanical, the intent is for the Cal …
