Watertight IP67 induction motors for 380–6600 V, 37–2000 kW (TÜV)
A series of three-phase squirrel-cage induction motors in IP67 design for voltages of 380–6600 V and power of 37–2000 kW. A motor at standstill withstands flooding without water ingress and starts again immediately after the water recedes. Such motors are installed at pumping stations in areas at risk of flooding, on ship decks and in ports.

Description
The tightness of the housing and terminal boxes is achieved by design, through long fitting surfaces, small tolerances and precise installation of components. The IPX7 design of the series was verified by TÜV Süd (Technical Report 713183484 / 2020). The test results for the motors MEBK 250 M, MEBK 315 S and MEBK 355 ML are extended to other frame sizes, because the sealing concept in them is the same and they differ only in length and built-in components.
Degree of protection IP67 means complete dust-tightness and protection against temporary immersion in water to a depth of 15 cm to 1 m for 30 minutes. The motors are made to IEC 34 and VDE 0530 in low-voltage and high-voltage versions. Low-voltage machines are supplied for 220–240/380–420 V or 380–420/660–720 V at 50 Hz and for 220–280/380–480 V or 380–480/660–830 V at 60 Hz. Frame sizes are up to 500, the housing is grey cast iron, cooling is IC411, and the number of poles is from 2 to 16. Class F insulation is used to class B, and the mounting arrangements are IM B3, B5, V1 and B35. For outdoor installation, motors with the shaft down (V1) are ordered with a rain cover. The standard coating RAL 7030 or RAL 1016 is suitable for the temperate climatic group to IEC 721-2-1 indoors and outdoors.
All motors undergo acceptance tests at the factory's own test field in Hennigsdorf (Germany). For other conditions the manufacturer produces low-, medium- and high-voltage motors with degrees of protection IP56 (strong water jets, splashing by waves), IP65 (cement industry, grinding plants, aggressive chemical environments, desert) and IP66 (ship decks and especially aggressive environments). The manufacturer advises determining the degree of protection by the actual conditions at the installation site, not by factory standards, and consults the customer on the choice.
Typical sites are pumping stations in areas at risk of flooding, cooling towers, water treatment plants, open ship decks, port facilities, beverage bottling lines and cooling systems. Among the deliveries are high-voltage IP67 motors for Egypt. The series is suitable as a replacement for sealed motors at water supply and wastewater pumping stations.
