1.2 Principle of Operation
The IHN800 generates heat by means of a large electrical
current that is magnetically induced in the workpiece by
a coil within the heater� The high voltage, low current
electricity flowing through the large number of windings in
the inductive coil induces low voltage, high current electricity
in the workpiece� Because the workpiece has the electrical
characteristics of a coil with a single, short-circuited winding,
the high current generates heat within the workpiece�
Because the heat is generated within the workpiece, all of
the heater components remain cool�
2 Description
The heating cycle is electronically controlled either in a TIME MODE, where the heating time is selected, or in a TEMP MODE
where the desired temperature is selected�
The heater can further be run on 50% capacity when small yokes are used or when there is a risk for too quick heating of
sensitive workpieces (e�g� bearings with C1 or C2 clearance)�
2.1 Components
The induction heater consists of an U-shaped iron core with a large induction coil on one of its legs� The control electronics
sits in a separate control box on top of the heater�
The temperature is controlled by means of a magnetic probe�
