Torque optimization of Synchronous Reluctance Motor for Electric Powertrain Application
2019 Fourteenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2019For electric propulsion systems, synchronous reluctance motors (SynRMs) are a competitive alternative to permanent magnet synchronous motors due to their low cost and robust structure. This paper presents the torque optimization of a SynRM designed for an electric powertrain application. The relationships between the torque of SynRMs and various design

Peaked-MMF smooth-torque reluctance motors
IEEE Transactions on Energy Conversion, 1990The authors investigate the steady-state torque characteristics of reluctance motors with nonsalient stator punchings, but with peaked rotating magnetomotive forces (MMFs). The torque calculation includes the effects of saturation and fringing and groove fluxes.

Torque control of switched reluctance motors
1998Abstract In the present chapter, first the fundamentals of switched reluctance motor drives are discussed. This is then followed by a description of various position estimators which can be used in position-sensor less switched reluctance motor drives.

Torque control of a three-phase direct reluctance motor
ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics, 2002This paper describes an open-loop torque control for a three-phase direct reluctance motor which can generate high torque at low speed. The command strategy presented in this paper consists of feeding the motor with three-phase sinewave currents. The torque ripple at low speed is considerably reduced.

Analysis and torque optimisation of switched reluctance motor
2006 IEEE GCC Conference (GCC), 2006This paper shows the developed torque of a 4 phase 8/6 poles switched reluctance motor by simulation tests. The analysis for the torque is computed by finite element method. The torque optimisation is investigated by changing the pole arc/pole pitch ratio (γ) of the stator, rotor and yoke dimensions.

Advanced torque control of switched reluctance motor
ISIE 2001. 2001 IEEE International Symposium on Industrial Electronics Proceedings (Cat. No.01TH8570), 2002This paper proposes a new torque control strategy for switched reluctance motor (SRM). Most of the established torque control methods implemented with pre-measured or pre-analyzed data, such as phase currents, rotor position and torque. The established methods require hard efforts and time for the repetitious measurement and analysis.

Torque-angle characterization of a Synchronous Reluctance Machine
2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016This paper presents torque-angle characterization of a Synchronous Reluctance Machine (SynRM). Advancement in power electronics and machine design have allowed these motors to be used in various industrial and traction drive applications. An appropriate torque-angle characterization can reduce the size of the converter and provide an optimal operation ...

Direct Torque Control for Switched Reluctance Motor to Obtain High Torque–Ampere Ratio
IEEE Transactions on Industrial Electronics, 2019The direct torque control (DTC) method was introduced into the switched reluctance motor to reduce its inherent output torque ripple. However, the conventional DTC method produces negative torque more or less, which reduces the torque–ampere ratio of motors. This paper proposes a new DTC method by three improvements.

Torque ripple minimization for variable reluctance motors
Mechatronics, 1994Abstract The design of current waveforms that minimize torque ripples in variable reluctance (VR) motors is addressed. The general problem of torque ripple reduction has been investigated by several researchers using various nonlinear models. The results have been design methods that require exhaustive measurements of motor characteristics.
