Calculation of stable normal modes, on the other hand, would require analytic continuation of M(ω) into the lower half-plane, Im(s) ≤ 0, by deformation of the contour in velocity space, or perhaps by numerical
The rotor will continue to accelerate until the motor reaches its maximum angular velocity, a value that is determined by motor parameters (but the calculation of which is not important for this analysis). To increase the amount of time during which the torque can be felt, it is necessary ...
