It is shown that the ambipolarity constraint which results from neoclassical transport theory with gyroviscosity and inertia sets lower limits on the edge density and/or temperature and/or Z eff gradients. Toroidal momentum co, respectively counter,‐injection reduces, respectively increases these lower bounds. Generally speaking, co, respectively counter,‐injection increases, respectively reduces, the rotation velocities. The theory has so far been developed for the high collisionality regime only.
