The outstanding performance density and rugged durability of these new motors are due to a range of innovative design measures and a modern housing concept optimized using the Finite Element Method (FEM).
In the cooling concept of the air-cooled flameproof variants, elements of the tube cooling have been integrated into the fin-cooled housing, bringing about a marked improvement in cooling performance, particularly of hotspots. At the same time, a modern fan design with internal coolant circuit helps additionally optimize heat dissipation. The water jacket-cooled variant has also benefitted from an innovated cooling concept which has significantly improved temperature distribution and heat dissipation. These measures have meant improved reliability and durability in both variants.
Design measures have also been implemented to improve the foot structure of the rugged housing for optimized vibration behavior. The flow-optimized fan cover design has reduced noise generation without compromising performance.
The flameproof terminal box of the Simotics HV C is designed for maximum compactness and is identical for both the 6 kilovolt (kV) and 11 kV version, with weight savings of up to several hundred kilograms. The flexibility afforded by the variable position of the terminal box helps simplify plant planning and installation. Internal cable ducts make the motor resistant to even the harshest of conditions and also help to reduce cabling work. The concept of integrated cabling shields the cables from all kinds of external influences.
The high-grade standardization of production processes and interfaces in the Simotics HV C and its integration into the whole range of available marketing and engineering tools help cut delivery times relative to performance.
