Efficient control of reluctance synchronous machines
IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002This paper shows that maximum efficiency control (ME) in reluctance synchronous machines (RSM) belongs to the class of constant angle control strategies. It is also shown that for all constant angle control strategies, efficiency is constant and independent of torque (current), being only a function of speed.

Design and optimization of synchronous reluctance machine
Proceedings of the 16th International Conference on Mechatronics - Mechatronika 2014, 2014This paper deals with the design of synchronous reluctance machine of the transverse-laminated type. Rotor design has been made for two different rotor geometries based on general design recommendations. These geometries are studied and compared by using 2D finite element analysis. The geometries are developed by optimization algorithms after that. The

Stability Analysis of a Reluctance-Synchronous Machine
IEEE Transactions on Power Apparatus and Systems, 1967A stability study of a reluctance-synchronous machine (synchronous-induction machine) is performed by applying the Nyquist stability criterion to the equations which describe the behavior of the machine during small displacements about a steady- state operating point.

Variable reluctance machine with synchronous capacitors
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016A synchronous variable reluctance machine (VRM) can work with either a grid connection or a capacitor bank, each would need to provide the machine with positive reactive power to counter the machine inductive coils. Simulation shows that synchronous Variable capacitance could improve the VRM power transfer, when working both as a generator and as a ...

Comparison of stator DC-excited vernier reluctance machines with synchronous reluctance machines
2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015Stator DC-excited vernier reluctance machines (DC-VRMs) are vernier reluctance machines equiped with additional DC field winding in stator to generate the exciting field, a rotating field similar to synchronous reluctance machines (SynRMs). This paper compares the electromagnetic performance of two non-PM reluctacne machines including DC-VRMs and ...

Nonlinear reluctance network method for synchronous reluctance machine analysis
2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015In rotating electrical machine design, the magnetic equivalent circuit based on the reluctance network method seems to be a fair tradeoff between computational time and precision. Therefore this paper deals with a semi-analytical calculation method of the direct and quadrature axis magnetic circuit in Reluctance Synchronous Machines (RSM) by the means ...

Reluctance Synchronous Machines and Drives
1996Abstract Reluctance synchronous machines (RSMs) and drives include a multitude of machine topologies in terms of rotor, stator windings, and stator current control. Line-start (constant speed) and inverter-fed (variable speed) applications are easily achieved in a power range from a few hundred watts to megawatts.

Effect of machine design on performance of reluctance synchronous machine
Conference Record of the 2000 IEEE Industry Applications Conference. Thirty-Fifth IAS Annual Meeting and World Conference on Industrial Applications of Electrical Energy (Cat. No.00CH37129), 2002Low torque ripple in electrical machines is generally required to reduce acoustic noise and mechanical resonance vibration. To design for low torque ripple, however, affects the average torque and the power rating of the machine. In this paper the effect of stator winding chording and rotor skewing on the average torque and torque ripple of the normal ...
