Motor is Risun's middle name. Founded in 1999, Risun Expanse Corporation specializes in the research and development, manufacturing, and marketing of DC brushless micro-motors and atomic coolers. Risun's micro-vibrator, the first commercialized brushless vibration motor in the market, is capable of generating vibrations of stable frequency, moderate intensity, and continuous ripples with low power consumptions and a long service life.
Risun places great importance on the exploration of new technology and the reliability and safety of products, which is evidenced by the winning of a local award for the industrial contribution to the magnetic technology in 2004 and the acquirement of international patents in the field of motor-related arts.
