As I understand it, getting flat torque on a real-world induction motor at low frequency is tricky because you aren't inducing current in the armature to the extent you would at higher frequency.
I think you are referring to is called cogging, and everything I have read says it becomes a real problem around 5hz, unless you get into real high dollar stuff.
