Remarks in the above graphics (valid for the sequent figures):
S1 (60K): torque output during continous operation at temperature rise of 60K;
S1 (100K): torque output during continous operation at temperature rise of 100K;
S3 –60%: load cycle in case of intermittent periodic duty, 60% means the ratio of working time
with constant load to the whole cycle;
S3 –40%: load cycle in case of intermittent periodic duty, 40% means the ratio of working time
with constant load to the whole cycle;
S3 –25%: load cycle in case of intermittent periodic duty, 25% means the ratio of working time
with constant load to the whole cycle;
Max.torque curve: it is the characteristics curve of max. torque, which can not be exceeded.
