Design for power rating of driven machine 2 ) check for thermal capacity is absolutely essential Designed power corresponding to

max. torque The listed factors are empirical values. Prere- quisite for their application is that the machin- ery and equipment

mentioned correspond to generally accepted design and load specifica- tions. In case of deviations from standard conditions, please refer to us.
