1.3 Distinguishing Feature
The distinguishing feature of the IHN010 induction heater is the fact that the workpiece can only be placed on the cone-shaped
workpiece support for heating� The energy transfer is contact-free, and is generated via the medium-frequency coil situated be-
low� The cone-shaped workpiece support creates an optimal magnetic field distribution in the rings of the rolling bearing, thereby
ensuring that heat is distributed homogenously� This design improves efficiency, resulting in lower power consumption and faster
heating, which significantly reduces the costs of heating the bearings� This special technology allows the device to be very light
weight and portable� In addition, the device is fitted with predictive temperature control (PTC)� For every heating process, the
temperature increase curve of the workpiece/rolling bearing is measured constantly, thereby opti mising the heating perfor-
mance� This ensures that the target temperature is achieved quickly without overheating the rolling bearing�
1.2 Principle of Operation
The IHN010 generates a magnetic field in the medium
frequency range (approx� 25kHz), similar to an inductive hot
plate� The magnetic field induces a voltage targeted on the
inner ring of the workpiece� This creates eddy currents, which
efficiently heat the workpiece� As the heat in the workpiece is
generated by the current flow, all other parts of the induction
heater remain cold� The heating process is based on the prin-
ciple of eddy currents, so the workpieces to be heated should
be composed of ferritic (magnetic) metals� In case of doubt,
simply check the workpiece using the magnet of the tempera-
ture probe� This patented heating method enables fast, easy
and energy efficient heating of workpieces�
2 Description
The operation of the heater is controlled by the internal electronics in either of two modes� The operator can either select the desi-
red temperature of the bearing in TEMP MODE or set the length of time that the bearing will be heated in TIME MODE� The power
level can be adjusted in steps of 20% for slower heating of sensitive workpieces (for example, bearings with C1 or C2 clearance)�
2.1 Components
The IHN010 induction heater is comprised of a portable housing with integrated operating electronics and cone-shaped
workpiece support� A temperature probe can be attached for measuring and monitoring the temperature of the workpiece�
The mains cable is enclosed separately, as are protective gloves for safe handling of hot workpieces� All of the equipment
can be stored in the practical carrying case�
