Loher is using this motor type to increasingly address large oil & gas projects (in addition to the standard business) - for example the industrial plants located in the huge gas fields in Qatar. The reason for this is that also here the design allows the motor to be individually adapted to the particular application, so that even extremely complex customer specifications can be fulfilled without any deviations. Further, the advantages include the low motor weight and the extremely simply motor installation and maintenance. LOHER Ex nA motors also have optimized parameters, i.e. the winding and rotor are optimally adapted to the environmental conditions. Only then can the optimum values for efficiency and power factor be achieved (without derating). The result is reflected in the energy saving with the lowest load on the line supply. A sensible investment for the future.
These motors are available up to approx. 315 kW. In addition to the usual types of construction (where the shaft and flange is also in conformance with NEMA), non-standard numbers of poles, pole-changing versions, high-speed designs as well as special cooling types are available - precisely to customer specifications. Our strengths also include special voltages / special frequencies / special insulation / converter operation.
Versions with special bearing designs for extremely high radial or axial (thrust) forces are especially worth noting.
