Based on its well-proven standard platforms, Loher precisely adapts its motors to the specific project and with the highest degree of flexibility - regarding the mechanical design, electrical design as well as special monitoring equipment and cooling types. This results in quite individual drives, perfectly tailored to the particular plant or system, application or customer specifications.
All parameters of the gray cast iron motors have been optimized, 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 for the lowest load on the line supply.
These motors are available in the following versions - surface-cooled (t.e.f.c.) - water cooled and as braking motor up to approx. 500 kW. In addition to the usual types of construction (where the shaft and flange is also in conformance with NEMA), special 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. The versions with special bearing designs for extremely high radial or axial (thrust) forces are especially worth noting.
