Fault-Tolerant Operation of DC-Field Excited Modular Variable Flux Reluctance Machine Under Open-Circuit Faults

IEEE transactions on industrial electronics (1982. Print), 2022
Dc-field excited modular variable flux reluctance machines (VFRM) are passive salient-pole rotor and independent stator winding, which makes it suitable for aerospace applications. Fault-tolerant operation is commonly required to improve its reliability.

Modulation Depth Maximization for High Phase Count Drives With Emphasis on Variable Pole Operation

IEEE transactions on industry applications
High-phase-count machines are well known to have reduced dc bus utilization compared to conventional three-phase drives. High-phase-count machines for fault tolerance and variable-pole induction machine drives are two examples.
