Under differentoperating conditions, the values obtained may vary from those listed here. In the case of extreme operating conditions, please consultyour Lenze sales office. Load capacity c of gearbox Characteristic value for the load capacity of Lenze gearedmotors. ˘ c is the ratio of the permissible rated torque of the gearbox to the rated torque supplied by the drive component(e.g. the built-in Lenze motor). ˘ The value of c mustalways be greater than the value ofthe application factor k calculated for the application. ˘ The type of load Application factor k (according to DIN 3990) ˘ The load intensity Takes into accountthe influence of temporally variable loads which are actually presentduring the anticipated operating time of gearboxes and geared motors. k is determined by: ˘ Temporal influences 1-6
