Large fans, compressors and crushers in the cement industry, metallurgy and power engineering have high power and operate for a long time, so they need a reliable high-voltage three-phase asynchronous drive.
High voltage motors can be directly connected to a 6 or 10 kV network, eliminating the step-down step, simplifying the system and reducing energy consumption. For example, the YX and YKK series cover dimensions from 355 to 800 mm, have class F insulation, continuous duty S1 and degree of protection IP44 or IP54.
The YKK series is equipped with an upper air-to-air heat exchanger, cooling - IC611, installation - horizontal on feet. The heat exchanger of two-pole motors of size 630 and above has a fan.
Operating tolerances are ±5% for rated voltage and ±1% for rated frequency. The motors maintain stable operation over a wide range of electrical conditions and ensure long-term continuous production of large industrial installations.
