One can verify this relation in two steps:
Firstly, reducing the torque to M cr/2,respectively increasing the speed to n 1= (n cr+ n 0)/2,
corresponding to I 1= (I cr-I 0)/2
Secondly, reducing the torque from M cr/2 to zero respectively increasing the speed to no
load speed n 0,corresponding to no load current.
In the first step, the reduction of power is smaller than in the second one.
So, the power is progressively reduced and finally cut off as the EPAC reaches the maximum
assistance speed.
