High-Precision Torque Control of Reluctance Motors
IEEE Transactions on Industry Applications, 1991A method for the high-precision torque control of a reluctance motor for servo applications is presented. The prototype is a three-phase, eight-pole reluctance motor driven by a MOSFET inverter. The current control as well as the speed control is performed by the software of a digital signal processor. The motor is supplied with sinusoidal current, and

Torque Harmonic Compensation in a Synchronous Reluctance Motor
IEEE Transactions on Energy Conversion, 2006The torque behavior of a synchronous reluctance motor [including the permanent magnet (PM) assisted configuration] is deeply analyzed. An analytical model is developed, showing the dependence of the torque ripple on the rotor geometry. The results of this model allow to individuate the position of the flux--barrier ends so as to minimize the torque ...

Improvement in torque profile of switched reluctance motors
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017Conventional drives for switched reluctance motors (SRMs) consists in supplying DC current pulses sequentially in each stator phase according to rotor position. This square current excitation produces a pulsating torque that limits the SRM applications.

A study on torque modelling of switched reluctance motors
2013 American Control Conference, 2013In this paper we develop and verify the suitability of two torque models of the switched reluctance motor (SRM). The first torque model is constructed analytically in terms of the well known flux saturation characteristics of the SRM. The torque modeling problem renders to an optimization process: minimizing the discrepancy between the model estimated ...

Torque Profile Optimization in Switched Reluctance Motor
2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019This paper explores the relationship between the rotor and stator geometries with the static torque characteristics of a Switched Reluctance Machine (SRM). As case studies, symmetric quasi-rectangular grids, small circular drill holes and various rotor arcs are introduced to the rotor and stator to gauge their impact on torque profile.

Control of torque in switched reluctance motor
2008 Second International Conference on Electrical Engineering, 2008Switched reluctance motor is gaining large interest of industry due to it mechanical simplicity, ruggedness behavior and low cost. On the other hand its advantages are over shadowed by need of intelligent control for its inherent issues like torque ripple, acoustic noise and high non linear characteristics. This paper focuses on torque ripple issue and

Unified theory of torque production in switched reluctance and synchronous reluctance motors
IEEE Transactions on Industry Applications, 1993A method is described for calculating the average and instantaneous torque of the synchronous reluctance motor from a knowledge of the trajectory of the phase flux-linkage versus phase current [i-/spl psi/] waveform, i.e., the same method as used with the switched reluctance motor.

Self synchronizing torque control of reluctance motor drives
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002The paper presents a new torque control scheme for synchronous reluctance motor drives that does not require any position transducer to synchronize the stator current vector with the rotor position, thus allowing a reliable and low cost realization as required in medium performance electric drives.

Design of low-torque-ripple synchronous reluctance motors
IEEE Transactions on Industry Applications, 1998A design approach oriented to the minimization of torque ripple is presented for synchronous reluctance motors of the transverse-laminated type. First, the possible types of rotors are classified and the more suited rotor structure is evidenced, to be matched to a given stator.
