This chapter presents advanced magnetless motor drives, including the synchronous reluctance (SynR), doubly‐salient DC (DSDC), flux‐switching DC (FSDC), vernier reluctance (VR), and doubly‐fed vernier reluctance (DFVR) magnetless topologies as well as the axial‐flux morphology. It gives an overview of the corresponding design criteria, design examples, and potential applications for EV propulsion. Similar to other motor drives, the advanced magnetless motor drives consist of four main components: magnetless machine, converter, sensor, and controller. There are different system configurations of the advanced magnetless motor drives, depending on the type of magnetless machines and the associated power converter. Differing from the DSDC machine, the FSDC machine allows for bipolar flux linkage and flux‐focusing arrangement, leading to offer higher torque density. The design criteria of advanced magnetless motor drives can be extended from their PM counterparts with the PMs replaced by field windings.
