Definitions

induction heaters are presently in use. Their use, however, is limited by several disadvantages derived from the fact that induction heating presently involves passing a high-power current, often of several kilowatts, through an inducting coil to effect high heat in tie conducting metal; and the primary winding is generally of normal supply frequency and is generally of substantial size which makes it difficult to transport.
Another disadvantage associated with prior art arrangements is that the bearing requires to be demagnetised during or after the heating operation.
an induction heater for a ring-like article includes a clamp-like magnetically inductive core, which can open to accommodate the article to be heated, a primary winding, and a source of high frequency electrical current, such as a switch mode supply.
the core is of ferrite.
the mains current to the circuit of the switched mode power supply 40 is rectified 42 and smoothed using electrolytic capacitors 44 to produce a smooth DC current.
This supply is then used to power a self-oscillating inverter circuit 46, the exact frequency of which is regulated by a control circuit 48, (the inclusion of such a circuit will be obvious to those skilled in the art), the resulting high voltage and high frequency current is then supplied to the primary coil 10, which then heats up any bearing or ring-like form 50, which is in inductive contact.
a ferrite core was selected which was suitable for use at frequencies of 20KHZ.
Type Philips A320 KP 9012 was used of size 94mm in length, 27mm in width and 16mm in thickness and several were assembled together to form the heater as shown in Figure 1. These were wound with 15 turns of 2 x 1mm copper wire.
a safety circuit will disable the switch mode power supply thereby inhibiting activation of said supply.
