Located in Changsha, central China′s Hunan province, Changli Electric Co., Ltd., a subsidary of Changli Group, which was formally known as Changsha Motor Factory founded in 1946, is a leading electric motor manufacturer among Top 10 industrial electric motor manufacturers in China. With over 70 years′ production experience and research and development capabilities, we can produce a wide range of motors. After years′ development, we have several branches, offices and marketing centers around the country.
With an investment of 1094 million yuan, the company covers an area of 400mu (about 270, 000m2), has over 600 sets of precision production equipment, with annual production capacity of 8,000 MW.
At present, we have over 350 employees, in which engineers and technicians accounting for 18%. With a strong technical research and development team and over 70 years′ manufacturing experience, we can produce various kinds of low voltage motors, medium voltage motors and high voltage motors.
Our testing center is Hunan Medium and Small Sized Motors Quality Supervision Station, an authorized test station of China National Quality Inspection Center, is responsible for the quality supervision and sampling inspection of motor products of various motor manufacturers in Central and Southern China. We can test 40 series of high and low voltage motors.
Our products include standard motors, synchronous/asynchronous motors, high efficiency motors, premium efficiency motors, explosion proof motors, special motors, variable frequency speed regulation motors, ultra-high speed motors, submersible motors, wound rotor slip ring motors, permanent magnet motors, large-sized vertical circulating pump motors, etc.
