According to the original report, China’s low-voltage inverter market reached RMB 13 billion in 2009, with more than 100 domestic businesses and brands. Their total output exceeded RMB 4 billion, representing approximately 30% of the market. Domestic vector inverters, a focus of motor energy savings, accounted for approximately 60% of that segment.
Growing recognition of vector inverters’ energy efficiency supported the inverter market. The original article described rapid growth in China’s AC motor variable-frequency speed-control market, citing an annual rate of 12% and broader use of high- and low-voltage inverters. It repeated the 2009 low-voltage market figures: RMB 13 billion in sales, more than 100 domestic businesses, and domestic output above RMB 4 billion, around 30% of the market, with domestic vector inverters representing approximately 60% of their segment.
Government programmes and standards supported variable-frequency motor adoption. Motor-system efficiency formed part of China’s medium- and long-term energy-saving plans and the Eleventh Five-Year Plan’s priority projects. Experts had advocated vector inverter technology since the early 1980s. Work during the Tenth and Eleventh Five-Year Plans included upgrading motors and drive systems, optimizing fans, pumps and compressors, and promoting variable-frequency speed control and automation. The original article also described a May 31 public-benefit programme that added motors after air conditioners. These policies and standards supported the adoption of energy-saving motor technology.
