Around seventy percent of electricity used in the industrial sector is utilised via electric motor drives. There are significant potential energy efficiency savings to be made in this area. Also many of Australia’s major trading partners now have or are progressing towards mandatory MEPS for three phase electric motors including Taiwan, China, USA, Canada, Thailand and soon Malaysia.
MEPS will improve the energy efficiency of appliances and equipment, particularly overcoming situations where the purchaser is not responsible for ongoing energy operating costs.
In general, the USA and Canadian MEPS levels implemented in 1997 were considered the basis for MEPS proposed for Australia for three phase electric motors to be introduced in 2006. These were chosen after detailed comparison of testing methods showed that these levels were achievable and that they were the most stringent currently in force or proposed by our major trading partners. These levels are also broadly equivalent to European Efficiency Level 1 for 2 and 4 pole motors and are currently specified as the “High Efficiency” levels in the 2001 standard for 2 and 4 pole motors.
