"Yamaha Motor Electromagnetic Environment Experiment Room" Completed

April 14, 1999

On April 14, 1999, Yamaha Motor Co., Ltd. (YMC) holds a ceremony to commemorate the completion of the "Yamaha Motor Electromagnetic Environment Experiment Room" that had been under construction since last June at a site in the Shinhirayama industrial park in Toyooka-mura, Iwata-gun, Shizuoka Pref., as a facility for research aimed at minimizing the impact of electromagnetic waves generated by Yamaha products on the environment.

Today, the rapid development of electronic technologies has made our lives much more convenient, but at the same time these sophisticated electronic systems have disadvantages in that they produce electromagnetic-wave noise and can also be made to malfunction as a result of electromagnetic-wave interference. As a result, countries around the world have set regulations to prevent such electromagnetic interference and these regulations are getting stricter year by year.

Many Yamaha products and components contain highly sophisticated electronic systems and in order to respond rapidly to the electromagnetic interference(EMI) regulations set by the different countries of the world, this new facility has been built to conduct technological research regarding the electromagnetic interference produced by these products and also their capability to withstand malfunction as a result of electromagnetic susceptibility (EMS), as well as giving us the facilities necessary to receive product certification under the qualification standards set by the different countries.

This new facility is designed to enable comprehensive technological development in the areas of EMI and EMS for the wide range of Yamaha products, including land vehicles (motorcycles, golf cars, snowmobiles, PAS bicycles, electric powered wheelchairs, etc.) and marine products (outboard motors, personal watercraft, etc.) and machinery (industrial robots, GHP, etc.). What's more, all the equipment and facilities meet international specifications that will enable certification under the standards of the different countries of the world.

This new facility is designed to enable comprehensive technological development in the areas of EMI and EMS for the wide range of Yamaha products, including land vehicles (motorcycles, golf cars, snowmobiles, PAS bicycles, electric powered wheelchairs, etc.) and marine products (outboard motors, personal watercraft, etc.) and machinery (industrial robots, GHP, etc.). What's more, all the equipment and facilities meet international specifications that will enable certification under the standards of the different countries of the world.

The new facility is build on a 3,875 square meter site and is a 2-story building with a total floor space of 1,736 square meters with respective electromagnetic environment experiment rooms for land vehicles and marine and machinery products plus the various measuring rooms on the first floor and rooms for evaluation of EMS performance for components on the second floor.
Features of the facility include a large dark room in which a distance of ten meters can be obtained between the measuring device (antenna) and the product being measured and, of particular note, the experiment room for land vehicles is outfitted with a roller chassis that enable both two- and four-wheeled vehicles to be tested with their wheels running as in normal operation, while the experiment room for marine and machinery products has water supply and drainage facilities for the marine products and high-voltage electrical supply and pressurized air supply necessary for industrial robots. All this gives the facility the capacity to conduct EMI and EMS evaluation on Yamaha's wide-ranging products. Experimental operations will begin at the new facility in April and plans call for European certification officials to be invited to conduct tests aimed at EMI and EMS product certification for motorcycles under European regulation standards beginning in July.

* "An electromagnetic environment experiment room" is a room that creates an ideal environment for making EMI and EMS evaluations of products by shutting out electromagnetic wave noise and also preventing electromagnetic wave reflection. In order to achieve this function the walls and ceiling of the room's interior are covered with a large number of electromagnetic wave-absorbing quadrangular pyramid shaped forms made of materials like ferrite or carbon that absorb electromagnetic waves. The interior is also outfitted with antennae for receiving electromagnetic wave noise as well as generating several types of electromagnetic wave noise along with the various types of product monitoring equipment.
