Characteristic curves

A vertical line is drawn through the specified working point of 160 Ncm, perpendicular with respect to the torque axis. The points of intersection of this straight line with the other curves results in the operating data for nominal speed nN, nominal current IN, and mechanical power output P2N.
 

Key for evaluation of characteristic curves

Example:

Given: M = 160 Ncm.

Found: nN = 3800 min^–1.

P2N = 600 W und IN = 35 A.
