Stepper motor of the national economy growth and slow down the development of the stepper motor is inseparable. Since reform and opening up, China's rapid economic growth, to increase investment in the infrastructure construction such as industry. Therefore, metallurgy, electric power, cement, construction, building materials, energy and other industries also get the leap development, slow down the step motor and expand market. As xiao-bo wu said & other; Manufacturing is the basic link of all industry & throughout; , the country of manufacturing is particularly seriously, picked up speed on the progress of major equipment localization, including slow step motor benefit a lot. In all aspects of the process of localization for mechanical equipment requirements is relatively high, although slow step motor in China in recent years had many breakthroughs in various aspects. But compared with foreign special reducer industry still has a gap. Throughout the global market scope of the gearbox, Germany, France, Britain, the United States, China, South Korea and other countries still maintained a leading technical level, but as the development and improvement of industrial technology in our country, many domestic brands continuing to provide the industry with more innovation and surprise. The han debao planetary reducer because of its excellent performance is more and more in the industry recognition. Domestic brands rise at the same time, doesn't mean we can take the larger the speed reducer of market share. Whether from the quality and effect, domestic slowdown stepper motor still has great room to improve, for the motor quality is everything.
