Investigating the Impact of Material Cost Fluctuations on the Total Manufacturing Cost of EV Traction Machines

Switched Reluctance Machine for Transportation and Eco-Design: A Life Cycle Assessment

“…In Table V are summarized the most for the ALU-winding SRM significative differences between CU-winding SRM and ALU-winding SRM configurations. The usage of aluminum winding represents a further mean for lowering cost of a machine that is intrinsically cheaper than other technologies as demonstrated in [2] where the total cost of the SRM is respectively 50% and 44% lower compared to a PMSM and to an IM. Indeed, cost per mass unit of aluminum is almost 3 times lower than copper.…”

“…With respect to the above-mentioned background, EM sustainability, both in terms of cost and environmental impact, plays a very important role in the race towards electrification. In this perspective a Switched Reluctance Motor (SRM) could represent a viable technology as it is well known for its costeffectiveness as described in [2], where SRM cost reduction potential is presented through a comparison with a permanent magnet synchronous machine (PMSM) and an induction machine (IM). SRMs lower torque density, high torque ripple and acoustic noise have determined a preference of other technologies for road applications, while robustness (with proper mechanical design), that is another characteristics of the SRM [3], together with the cost advantages, make this technology suitable for off-road applications, less sensitive to the intrinsic SRMs drawbacks [4].…”
