发帖数: 687 | 1 Let q=y', then q'=y^3-y. Work on the y-q plane.
Observe that any level curves of
F(y, q)=0.5 q^2 - 0.25(y^2-1)^2
is a solution to your ODE. Most such curves are regular. The
separatrix are the parabolas
q=(y^2-1)/(\sqrt 2) and q=-(y^2-1)/(\sqrt 2).
You can check that if you start at any point inside the domain
bounded by these two curves, i.e.
-(y^2-1)/(\sqrt 2)< q <(y^2-1)/(\sqrt 2) with -1
you get periodic solutions. Exclude (0, 0) if you don't want constant
solution.

but in terms of the motor in this pdf
I won't call the initial stage of its torque curve "flat"
of course
the output of the motor is controlled by the variable frequency drive
so you can definitely make a torque curve plateau as you want
but what's the reason?
is there any special interest for you to do that?
I don't think so...
to me, things sound pretty simple:
you want to make such a torque curve to fit your transmission
