Flux weakening of hybrid synchronous machines
IEMDC 2001. IEEE International Electric Machines and Drives Conference (Cat. No.01EX485), 2002In this paper, we present a study of control laws adapted to so-called "double excitation" or "hybrid" structures. We display, among other things, the contribution of hybrid excitation, which provides an additional degree of freedom in comparison with classical structures.

Reduced DC-link capacitance permanent magnet synchronous motor (PMSM) drives have many advantages, such as longer lifetime, reduced cost and higher power density. However, due to the DC-link voltage fluctuation, the DC-link voltage utilization rate and the torque ripples are two major issues in flux-weakening operation region.

Flux weakening operation of switched reluctance motors
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002Speed can be increased above base speed by flux weakening in the DC machine. The relationships of torque, power and speed have been characterized for the DC machine when operating from zero speed to twice base speed. To date, no such research has been performed on the switched reluctance motor (SRM) above base speed.

Optimal voltage feed-back flux-weakening control of IPMSM
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011A voltage feed-back flux-weakening (FW) control scheme for vector-controlled Interior Permanent Magnet Synchronous Motor (IPMSM) drive is considered in this paper. The voltage controller is based on the difference between the amplitude of the reference voltage space vector and a proper limit value, related to the feeding inverter limitations, and ...

Ironless Axial Flux PM Machine With Active Mechanical Flux Weakening For Automotive Applications
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006Because of their high compactness and lightness, together with high efficiency, Axial-Flux PM (AFPM) machines are among the most suitable candidates for several automotive applications. As a drawback, they are limited in speed range because voltage rises linearly with speed.

Flux Weakening Control for Dual Three-Phase PMSM
2018 Asia-Pacific Magnetic Recording Conference (APMRC), 2018Control strategies for dual three-phase permanent magnet synchronous motors (PMSMs) mostly focus on the reduction of harmonic currents and torque ripple. But the investigation on the control approach on the dual three-phase PMSM in high-speed region has not been well discussed before. This paper aims to present a new flux weakening control scheme for a
