A Detailed Study for the Determination of Phase Inductances of a Shaded-Pole Induction Motor with Variable Air Gap

open access: yesGazi Üniversitesi Fen Bilimleri Dergisi, 2019
Shaded-pole induction motors (SPIMs) are extensively used in industrial applications, home appliances and ventilation systems due to their simple structure, low cost and low maintenance requirement.

Designing Ultrahigh Frequency Motor Rotor Position Search Coils for Electric Propulsion in Drones

open access: yesDrones, 2023
As the core of electric propulsion in drones, the motor has higher requirements for its reliability and fault tolerance. Accurate acquisition of rotor position information is a prerequisite for a motor-driven drone’s system to operate stably. Traditional

Frequency Dependent Model of Leakage Inductance for Magnetic Components [PDF]

open access: yes, 2012
Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known

Microwave Kinetic Inductance Detectors [PDF]

open access: yes, 2005
Low temperature detectors have been a subject of intense interest to the scientific community over the last decade. These detectors work at very low temperatures, often well below 1 Kelvin, to minimize the noise in the measurement of photons.

Misoprostol and attempted self-induction of abortion [PDF]

open access: yesJournal of the Royal Society of Medicine, 1998
Sporadic reports have documented the use in countries such as Brazil and Mozambique of misoprostol to self-induce pregnancy termination (PT). This paper presents the case of a young woman from Mozambique who presented to a UK surgery requesting PT .

Mapping Methodology for Self and Mutual Inductance Profiles in IPT Systems

open access: yesEnergies, 2022
Magnetic couplers (MC) are the key element that enable the power transfer over large air gaps in inductive power transfer (IPT) systems. Numerous designs with different coil and core arrangements have been proposed in the literature.

Improved Formulae for the Inductance of Straight Wires

open access: yesAdvanced Electromagnetics, 2014
The best analytical formulae for the self-inductance of rectangular coils of circular cross section available in the literature were derived from formulae for the partial inductance of straight wires, which, in turn, are based on the well-known formula ...
