A. With a known output torsion of the motor,strick a corresponding N, I, P, η value under this torsion.
Finds the correspinding torsion position in the absciussa,do a vertical line to identify the intersections of this line with four function lines.Respectively do the horizontal line to intersect longitudinal coordinates of the corresponding parameters.Then parameter values can be received right away.
B. Known any value of the 4 parameters of N, I, P, η strick other parameters.
Take known value N as an example .First, corresponding numerimal point in the longitudinal coordinates of N . Do a horizontal line intersecting the N =f(T) lines ,to identify intersection,and pass it to make the vertical line.It crosses with other charateristic lines and the intersection of the line with the abscissa is the corresponding torsion value.Do the horizontal lines passing other of intersection of characteristic line,finding corresponding longitudinal coordinates.The corresponding parameters can be obtained.
