The Importance of EMC
The purpose of this article is to discuss the EMC problem and to briefly illustrate its relevance in the development, manufacturing and sale of commercial escalator components in Australia. The intent audiences of this report are engineers and managers from WTM, an escalator development company planning on entering the Australian market. Electromagnetic interference or EMI caused by radiation has been a known problem ever since the very earlier days of the electronic age. In some cases, electromagnetic interference can cause severe conflicts between electronic devices operating in the same environment. Today, with the rapid spread of electrical and electronic devices, electromagnetic compatibility (EMC) has become a subject gathering ever increasing interests and attention. Electromagnetic compatibility is known as the discipline of designing, analysing and testing of electronic equipment, to ensure that they are compatible with their electromagnetic environment. By conforming to the EMC regulations in the design stage, we reduce the potential of discovering design problem after the design has left the development laboratory. The definition of EMC can also be described using the terms EMI and EMS.
In today's world of electronics, it is necessary to deal with standards for electronic emission and susceptibility levels. The standards are guidelines for emission and susceptibility limits allowing electronic devices to coexist in the same environment. These standards are not static, as technology improves, new standards are established while existing standards are abolished. In any case, there should be at least one person in the company responsible for the management of EMC regulations, engineering and contacts to the consultants. Thus it is very important for TWM to consult the Australian Spectrum Management Agency of the Australian Communications Authority for a more concise reference for implementing measures which must be taken to assure that the products complies to the Australia EMC Standards. Generally, the earlier EMC is taken into account during development, the lower the expense. From test cases, additional production costs fall between 1-5%. If the issue of EMC is considered after the development phase, the production costs can be significant higher. And if measures were taken after production, the costs will increase by another 30%. Apart from suffering lower profit, the entire manufacturing process will experience long delays, thus reduced market share. Normally, a product's conformity has to be proof-read by a type test on EMI and EMS. The results must be within the allowed toleranc
