TL;DR: In this paper, a direct-drive double rotor Vernier panent magnet (DR-VPM) machine is proposed and analyzed, and its steady and transient performances are analyzed using circuit-field-motion coupled time-stepping finite element method (CFM-TS-FEM).

TL;DR: In this paper, the authors developed a general design guideline for split-slot low-speed Vernier permanent magnet (VPM) machines, generalize the operation principle, and illustrate the relationship among the numbers of the stator slots, coil poles, permanent magnet pole pairs, thereby laying a solid foundation for the design of various kinds of VPM machines.

TL;DR: This paper proposes and implements a new three-phase 12/8-pole brushless doubly fed doubly salient machine (BDFDS) for wind power generation that can offer constant output voltage and efficiency optimization over a wide range of wind speeds.

TL;DR: In this paper, a new double-stator cup-rotor permanent-magnet machine is proposed and implemented for wind power generation and the circuit-field-torque coupled time-stepping finite element method is utilized to analyze the proposed machine.

TL;DR: This paper systematically studies a new kind of PM machines with both stator and rotor PM excitations, namely, dual-PM excited machines, and proposes the general design principle of these machines, based on the flux modulating effect.
