Inductors used in induction heating equipment are likened to tools used in conventional machine tools. They are also known by various nomenclatures such as coil, heating conductor, heating loop etc.,. Inductors are often masterpieces of craftsmanship. It involves skill as well as experience both in design and manufacture to bring out a working model of inductor. Various criteria are required to be applied to the process of design and subsequent manufacture of inductors.

Aestus follows the classical approach to the field of inductor design & manufacture. A brief summary is as follows:

		One of the important design criteria is to ensure optimum coupling efficiency of the inductor with work piece. This is decided together with data on mechanical accuracy of the handling system and power source specifications.
		Profile of the inductor is primarily inspired by the desired heating pattern. Other factors such as production rate, design of the handling machine and automation related to entry and exit of work pieces into the inductor also have an influence in this matter.
		Selection of cross section of copper is based on the applied frequency and the required flow of cooling water.
		Ultimate geometry of the inductor is always an evolution through trials but starting with the readily available emprical data and inputs from experience can save time.
		Professional evaluation regarding use of flux intensifiers (materials of high magnetic permeability) is necessary balancing technical need and economics.
		Duplication of inductors becomes easier by use of jigs in assembly.
		Mechanical rigidity is essential considering the power density, applied frequency and duty cycle of operation.
		Change over time is an important factor to consider to reduce idle time of the equipment. Fixing and removal of inductors should have "quickchange" arrangement, wherever feasible.

The inductor manufacturing division at Aestus is equipped with skilled manpower, tools, jigs and test equipment to manufacture and inspect quality inductors. Implementation of ISO 9001 is under progress and our operations will comply to the standards of this quality system by the end of this year.
