Quite often, enterprises face problems when, due to the peculiarities of the technological production process, natural heat removal from the working units of the electric motor is impossible, and the use of forced air cooling is impractical due to its bulkiness and inefficiency, in this case the only possible solution is the use of a water cooling circuit. This problem is especially relevant for technological processes with high temperature conditions (in the production of cement, bricks, building materials, metallurgy, glass factories, etc.)
The use of water cooling also makes it possible to reduce the overall dimensions of the engine (in conditions of limited space), reduce noise and vibrations (when working in category rooms, test laboratories), reduce the influence of the electric motor on the temperature regime in the room, prevent the spread of dust and air flows.
Parameters asynchronous motors with water cooling W series:
- Rated power: 11 - 1800 kW;
- Overall height: 160 - 500 mm;
- Degree of protection: IP55, IP56;
- Cooling method: IC7A1W7;
- Insulation class: F, H;
- Temperature regime: (subject to agreement).
Additional options: feedback sensor, manufacture of a special shaft or additional shaft, anti-condensate heater, reinforced bearing shield, vibration sensors, nipples for replenishing bearing lubrication, adaptation of connecting dimensions, manufacture of mounting platforms.
A practical example: In the summer of 2010, our colleagues turned to us for advice, they had a constant shutdown of electric motors at the rubber harvesting site, the electronics showed thermal overheating of electric machines. After visiting the enterprise, the reasons were established: firstly, it is the ambient temperature in the region of 60 ° C, and secondly, the constantly deposited soot on the cooling fins of the electric motor prevented its natural cooling. In 2011, we installed Electro Adda water-cooled electric motors on rubber mixers where the maximum ambient temperature was observed.
