This article presents a pioneering brushless dual-electric-port machine (BLDEPM) distinguished by its unique ac flux-control features. Utilizing a dual-stator, stator dual-electric-port design, the BLDEPM incorporates armature windings and ac field control windings, allowing for brushless operation without the requirement for rotor windings. Unlike traditional dc hybrid-excited machines, the control winding is powered by ac currents, enhancing current control flexibility. In overload conditions, the control winding serves as power winding, injecting q-axis current to enhance torque, and optimizing space utilization and torque density. Conversely, during high-speed flux weakening, the control winding transforms into the flux-control winding by injecting a d-axis current, capitalizing on coupling effects between the d-axis of the two winding sets. This article initially presents the machine’s topology and operating principles, followed by an evaluation of electromagnetic performance using a finite element method (FEM) and an analysis of ac flux-adjusting principles. Finally, a novel fault-tolerant strategy, injecting only field current, is proposed, leveraging high redundancy. The machine demonstrates superior performance in torque density, flux weakening, and fault tolerance, making it promising for electric vehicle (EV)/hybrid electric vehicle (HEV) applications. Experimental verification of a prototype confirms the feasibility of the proposed machine.
