Recently, the magnetic resonance type of transmission is gaining attention
as a wireless transmission technology. Magnetic resonance allows transmission
very efficiently from a distance of several meters and the axes of the
transmission end and receiving end of the coils do not need to be aligned,
which differs from the conventional electromagnetic induction type transmission
that is widely used today. Investigating the coils via analysis is advantageous
because an optimal design for the coil geometry and circuit for the frequency
to use is necessary to transmit from the transmission coil to the receiving
coil using resonance.
This example presents the use of a magnetic resonance analysis to obtain
the transmission efficiency and magnetic flux density distribution for
the magnetic resonance by changing the distance between the coils. |

| An inductive power supply system is a device which transmits power by electromagnetic
induction without physical contact. The system can be used for various
applications, such as moving devices, rotating devices, and devices placed
in closed spaces.Because the primary side and the secondary side of a transformer
are separated by a gap, and the flux leakage and efficiency vary with the
position of the two sides, obtaining the position of each characteristic
is advantageous.This example presents the use of a magnetic field analysis
to obtain the transmission characteristics of an inductive power supply
system when the position of the primary and secondary sides changes. |

| Inductive power supply system is a device which transmits power by electromagnetic
induction without physical contact. The system can be used for various
applications, such as moving devices, rotating devices, and devices placed
in closed space. Since the primary side and the secondary side do not contact,
magnetic flux leakage and efficiency vary with the position of the two.
Therefore, it is important to evaluate how their positions affect each
characteristic by simulation. This note presents the use of magnetic field
analysis to obtain the power transmission efficiency by moving the position
of power cable in horizontal direction and in vertical direction. |
