New Motor Designs Help EV Makers Kick the Rare-Earth Habit (Part 3) (Download)

Sept. 6, 2023

Advanced electric motors can help give tomorrow's electric vehicles more range and performance while reducing or eliminating the need for rare-earth minerals found in the permanent-magnet synchronous motors (PMSMs) that have been widely used until now.1

Part 1 of this series explored several wound-rotor synchronous motor (WRSM) architectures and how they can be near-drop-in replacements for PMSM units. Part 2 examined the properties and application challenges of switched reluctance motors (SRMs), one of the most common types of so-called induction machines.

Part 3 looks at synchronous reluctance motors (SynRMs), another promising sub-species of induction-type machines.
