| Induction heating is a method to produce heat using electromagnetic induction.
When a magnetic field generated by the coil produces eddy currents in the
iron sheet, the iron sheet is heated with the Joule heat produced by the
electric resistance between the eddy currents and the iron sheet. Compared
to other methods of heating, surfaces can be rapidly heated, or heating
can be localized.This example introduces an analysis to obtain the temperature
distribution on the surface of an iron plate heated by high-frequency induction
heating. |

| A constant velocity joint is located on both ends of the drive shaft in
the drive system of a car. The high-frequency induction heating may be
used to harden the inner ball track inside the outer ring of the constant
velocity joint, because the inner ball track is directly in contact with
the steal ball and the roller on the side of the inner ring. It is important
to take account of temperature rise and the timing of it inside of the
heated object for designing of induction heat system such as high-frequency
hardening. In JMAG, the loss distribution obtained from magnetic field
analysis can be used as a heat source for thermal analysis to obtain the
temperature distribution and the temperature variation caused by high-frequency
induction heating. This note presents the use of a coupled magnetic field
analysis and thermal analysis to obtain temperature distribution for the
outer ring of the constant velocity joint. |

| An induction furnace is an electrical furnace in which the current is generated
within the metal by induction heating and the heat generated by the electric
resistance melts the metal. The magnetic iron cores around the coil are
used to protect the coil from being damaged. The magnetic iron cores also
prevent the flux leakage so that the steel sheet outside the iron cores
will not be heated. This note presents the used of magnetic field analysis
to evaluate the flux leakage from the magnetic flux density distribution
of an induction furnace with and without the iron cores. |

| The high-frequency quenching method uses induction heating to harden the
surface of objects.The temperature of the gear at the time of quenching
affects the hardness of the gear. The surface temperature distribution
varies with the coil geometry.In JMAG, the eddy current loss density distribution
obtained by magnetic field analysis can be used as a heat source for thermal

| A high-frequency heat treatment is used to process a variety of machine
parts since it has high thermal efficiency and has fewer harmful effects
such as oxidization. When the high-frequency heat treatment is applied
to the steel wire, the maximum temperature of the steel wire and the temperature
variation at the time of quenching significantly affects the strength and
toughness of the steel wire. In JMAG, the eddy current loss density distribution
obtained by magnetic field analysis can be used as a heat source for thermal
analysis.This note presents the use of coupled magnetic field analysis
and thermal analysis to obtain the temperature distribution and the temperature
variation of the steel wire. |
