Optimal 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 کاملTorque 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 کاملDetecting and Tolerating Faults in Switched Reluctance Motors
The switched reluctance motor (SRM) has inherently high level of fault tolerance. However despite of its high robustness and reliability it can face windings and bearings faults. The faults can cause costly downtimes in industrial environment, or they can bring about more severe consequences in safety critical applications. Therefore the detection of the faults in their incipient phase and the ...
متن کاملAdaptive torque-ripple minimization in switched reluctance motors
This paper addresses torque-ripple reduction in current-fed switched reluctance motors (SRMs). Ripple-free torque production in SRMs requires an accurate model that is often too complex for practical implementation. The algorithm proposed here combines the use of a simplified model with adaptation. Explicitly, it includes dynamic estimation of low harmonics of the combined unknown load torque a...
متن کاملTorque ripple reduction in switched reluctance motors – A review
The generated torque ripple in switched reluctance motors (SRM) can be considered as one of the major disadvantages of the motor. It is mainly due to frequent switching of phases for rotation of the motor and changes of the air gap length between the rotor and stator teeth. It decreases the average developed torque, diminish the efficiency, causes noise and vibration in the motor. So, in order ...
