Torque ripple, vibrations, and acoustic noise in switched reluctance motors
The paper presents a state of the art review on the subject of torque ripple, vibrations, and acoustic noise in Switched Reluctance Motors (SRM). The approach of the multi-phase operation of SRM is also reviewed. Moreover, further directions of research on these subjects are introduced.
متن کاملDesign Optimization of Switched Reluctance Motor for Noise Reduction
Article history: Received: 5.1.2016. Received in revised form: 15.3.2016. Accepted: 15.3.2016. With finite element method (FEM) using ANSYS finite element (FE) package, an electromagneticstructural simulation model is introduced for the switched reluctance motor (SRM). Since the main reason of noise and vibration in the SRM is a radial force applied to stator poles, the 2D FE transient analysis...
متن کاملOptimal design of switched reluctance motors
The fundamental theory of the switched reluctance motor is presented with a number of new equations. It is used to show how the practical development of a design calculation should proceed, and this leads to a discussion of physical characteristics required to achieve satisfactory performance and to reduce acoustic noise. The paper makes a few generic observations on the characteristics of succ...
متن کاملLow-Noise Switched Reluctance Drive
Switched Reluctance (SR) Motor Drive is of great topical interest. It has the potential lo emerge as a viable option for variable speed applications. Though simple in construction, the motor is quite rugged, and has many attractive /eatures like high torque-to-inertia ratio, fault tolerance, and high eficiency. A number of converter topologies are prescribed for driving the motor. However, its ...
متن کاملComputer-optimised smooth-torque current waveforms for switched-reluctance motors
The paper discusses the design of current waveforms for switched-reluctance motors, which give rise to a constant (ripple-free) torque. The waveforms are optimised by computer search techniques, to give the lowest RMS current per phase consistent with producing smooth torque. Furthermore. the waveforms are constrained to be within the converter’s VA rating. Current waveforms and the associated ...
