Thermal Analysis of Synchronous Reluctance Machines – A Review

Electric Power Components and Systems, 2019
Synchronous Reluctance Machines (SynRMs) are facing a revamped industrial interest. A comparison between SynRMs and other types of electric machines allow listing the advantages and proving the choice of such machines. This paper presents a review of SynRMs, regarding particularly their thermal analysis.

Control of synchronous reluctance machines

IEEE Transactions on Industry Applications, 1993
This work develops a comprehensive approach to the control of inverter-fed synchronous reluctance machines (SYNCREL), based on the machine's ideal model. From the theory a control simulation is designed. Simulation and experimental results are presented. The effects of saturation and iron losses are briefly considered. >

A Comparative Study of Cycloidal Reluctance Machine and Switched Reluctance Machine

IEEE Transactions on Energy Conversion, 2021
A variable reluctance electric machine with a two-degree of freedom rotor motion characterized by rotation around the center of the rotor and orbiting around the center of the stator is studied. One motivation for adopting such rotor motion would be to allow torque generation through both the radial and tangential components of the electromagnetic ...

Stability of reluctance machines

Proceedings of the Institution of Electrical Engineers, 1971
An experimental and theoretical study of rotor oscillations in reluctance machines, with particular reference to variable-frequency systems, is described. Measured performance characteristics, both steady-state and transient, are used to indicate the basic features of the oscillation and to confirm the validity of theoretically derived results. Machine

Reluctance Mesh-Based Modeling of Switched Reluctance Machines

2021 IEEE Transportation Electrification Conference & Expo (ITEC), 2021
Design of switched reluctance machines requires repetitive finite element (FE) simulations with considerable computational time and burden. These simulations slow down the design process and require powerful computational resources. The magnetic equivalent circuit (MEC) technique resembles an alternative with a reasonable computational time and fair ...

The Reluctance Machine as a Self-Excited Reluctance Generator

Electric Machines & Power Systems, 1985
ABSTRACT The test described in this paper show that the reluctance machine may be operated as an independent or isolated generator at a predetermined voltage and frequency, with sinusoidal wave form, by moans of capacitive excitation. Further, proper choice and arrangement of the capacitors will result in a practically flat external load-voltage ...
