Vibration modes and acoustic noise in a four-phase switched reluctance motor [PDF]

open access: yes, 1996
Acoustic noise in the switched reluctance motor (SRM) is caused primarily by the deformation of the stator lamination stack. Acoustic noise is most severe when the periodic excitation of the SRM phases excites a natural vibration mode of the stack.

The Concept of Reluctance and Reluctance transactions in terms of Iraqi Law and Islamic Jurisprudence [PDF]

open access: yesمطالعات تطبیقی حقوق کشورهای اسلامی
A reluctance contract is a contract in which the reluctant person does something reluctantly and with the reluctance's threat without consent. A reluctant person only lacks satisfaction and self-esteem, but has the intention of making a deal.

Sensored and sensorless speed control methods for brushless doubly fed reluctance motors [PDF]

open access: yes, 2009
The study considers aspects of scalar V/f control, vector control and direct torque (and flux) control (DTC) of the brushless doubly fed reluctance machine (BDFRM) as a promising cost-effective alternative to the existing technological solutions for ...

Analytical Design of Sculpted Rotor Interior Permanent Magnet Machines

open access: yesEnergies, 2021
A computationally efficient design of interior permanent magnet (IPM) motor rotor features is investigated utilizing analytical methods. Over the broad operating range of IPM machines, interactions of MMF sources, permeances, and currents result in ...

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]

open access: yes, 2006
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...

Analytical Method for Compensation Choke Geometry Optimization to Minimize Losses

open access: yesIEEE Access, 2022
The article presents an analytical method for optimizing the geometry of the magnetic core of a three-phase compensation choke. The method describes the process of identification the fringing magnetic fields and the corresponding magnetic reluctances of ...

Performance optimization in switched reluctance motor drives [PDF]

open access: yes, 2011
In this paper, switched reluctance motors (SRM) are proposed as an alternative for electric power assisted steering (EPAS) applications. A prototype machine has been developed as very attractive design for a steering electric motor, both from a cost ...

On the Origin of the Magnetic Concentration Gradient Force and Its Interaction Mechanisms with Mass Transfer in Paramagnetic Electrolytes

open access: yesFluids, 2021
The objective of this work is to analyze the origin of the magnetic concentration gradient force. The force will be studied in a diffusion system where a paramagnetic electrolyte diffuses through a thin, inert membrane under the influence of a ...
