Scalability of Synchronous Reluctance Machines Considering Thermal Performance
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019Synchronous reluctance (REL) machines attract increasing attention in recent years, mainly due to the merits of cost-saving, high-efficiency, low-maintenance and high-reliability. For industrial mass production, the development of machines with a series of power ratings is of great demand.

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 ...

Synchronous Reluctance Machine Optimization for High-Speed Applications
IEEE Transactions on Energy Conversion, 2018The synchronous reluctance machines with transversally laminated rotor and multi flux barriers per pole reach a high torque density, so that they are proposed as a valid alternative to permanent magnet machines. Such machines have been analyzed for different applications, mainly home appliance, industrial tool, traction, up to low-speed high-power ...

Robust control of high-speed synchronous reluctance machines
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015High-speed regimes allow an increase in the power density of electrical drives, which is a necessary characteristic in aeronautical applications. In such a context, together with the typical nonlinearities of low-speed drives, i.e., core saturation, phenomena related to high fundamental to sampling frequency ratios appear increasingly significant. This

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.

Rotor design optimization of synchronous reluctance machine
IEEE Transactions on Energy Conversion, 1994It is demonstrated that the rotor design of synchronous reluctance machines can be optimized in terms of a key geometric parameter, i.e., the ratio of the rotor insulation width to the rotor iron width so as to obtain maximum torque production. The equation which gives the maximum motor power factor in terms of the saliency ratio has been derived and ...

Iron loss calculation for synchronous reluctance machines
Proceedings of International Conference on Power Electronics, Drives and Energy Systems for Industrial Growth, 2002A numerical method for electric machine iron loss calculation is presented in this paper. The method is suitable for any synchronous and most DC machines, especially if the current waveforms are known a priori. This technique will be principally useful for high-speed machines and in particular for the synchronous reluctance machine, where the iron ...

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
