Medium voltage motors are used in all industries in which heavy loads are moved or work is carried out in conjunction with particularly complex applications. Since 1946 they have been part of our extensive range of reliable, high-efficiency industrial motors for cement plants, pump systems, mines, the chemical, oil and gas industry, plant manufacturers and other users worldwide.
Changli manufactures medium to high voltage asynchronous motors up to 13800 V (13.8 kV) with squirrel-cage rotors up to 20000 kW (20 MW) as well as slip ring rotors up to 20000 kW (20 MW). Various electrical and mechanical designs as well as all types of protection and cooling are possible. Our motors are designed for mains or inverter operation and comply with the current standards IEC60034 and GB/T13957-2008, DIN and ISO.
