Presenting to a standing room only crowd, Munro & Associates’ Cory Steuben, account director, offered automotive engineers objective technical information about today’s leading EVs during two sessions at The Battery Show North America recently held in Novi, Mich.
During two presentations, Steuben compared EV systems integrations across car companies/vehicles and demonstrated why a vertically integrated company, such as Tesla, is leading the way and why the domestics must rethink their designs if they want to catch up.
Steuben first presented “Tesla Model 3 vs. Jaguar I-PACE Motor Insights” where he showcased two disassembled electric motors: one Tesla Model 3 internal permanent magnet (IPM); and one Jaguar I-PACE IPM.
“When it comes to motors, we see many different attempts across many manufacturers—particularly with the geometry of how they put the magnets into their internal permanent magnet motors,” said Steuben. “When you look at the ideal shape is actually very expensive to manufacture—it would be three or four sets of parabolic magnets. There is no common orientation. With the Jaguar, we see three stacked magnets, all neodymium-ferrite-born magnets which is similar to others in the magnet material. Tesla does a simple single V. We have seen six or seven variations in various forms.”

Steuben also presented “Electric Vehicle System-Level Integration Trends & Thermal-Electrical Management Synergies,” where he provided a detailed report on the system-level integration advancements that are impacting the OEM-level development of thermal and electrical systems. He highlighted system integration trends from the past and present, with a focus on the Tesla Model 3 Superbottle and integrated system.
