Continuous electromagnetic launcher using soleniod coil
IEEE Transactions on Magnetics, 1987This paper describes the characteristics of the continuous electromagnetic launcher as a linear electromagnetic actuator capable of allowing a magnetic substance like a steel ball to move at high speed. The launcher employs magnetic field generated within a solenoid to produce large, instantaneous thrust. This paper discusses the characteristics of the

IEEE/ASME transactions on mechatronics, 2019
Electromagnetic coil systems (ECSs) have been widely used for actuation and motion control of magnetic micro/nanorobots. In this paper, two typical ECSs with different system configurations are developed: One is computer-based and uses servoamplifiers ...

Review of Scientific Instruments, 1975
The second derivative of the axial magnetic flux density is found to vanish for an electromagnet composed of three circular coaxial coils if the spacing between adjacent coils is a, if each coil contains equal ampere turns, if the radii of the end coils are a, and if the radius of the center coil is ∼5a/4.

IEEE Transactions on Plasma Science
The trigger position, the number of coil turns, capacitance, discharge voltage, the ratio of length to thickness of the driving coil, and the ratio of length to thickness of the projectile are the key system parameters that affect the projectile exit ...

Optimized coils for electromagnetic induction systems
SPIE Proceedings, 2013Electromagnetic induction (EMI) systems often use separate transmit and receive coils. In these systems, it is desirable for the transmit and receive coils to have minimal mutual coupling and a maximum eld product, thus maximizing the detection depth. We demonstrate that a pair of spiral coils can be optimized to achieve these desired properties.

Analysis of coil temperature rise in electromagnetic forming with coupled cooling method
International Journal of Applied Electromagnetics and Mechanics, 2020The long-life driving coil is the prerequisite for electromagnetic forming industrial application. Up to date, the temperature rise is one of the major factors that restrain its working life.

Implementation of optimized electromagnetic induction coils
SPIE Proceedings, 2014Electromagnetic induction (EMI) systems often employ separate transmit and receive coils that are placed in close proximity to one another. This placement is desirable for packaging reasons, but it makes achieving minimal mutual coupling between the two coils difficult.

Electromagnetic actuator for voice coil
The Journal of the Acoustical Society of America, 1979An electromagnetic actuator for linear driving of movable heads of a magnetic disc unit in an information processing system. A plurality of slits or plates are provided with a magnetic pole inscribed directly on the internal surface of a permanent magnet, and increase magnetic reluctance of the magnetic path and reduce inductance of a moving coil, thus
