An equation for stationary MHD equilibrium with azimuthal rotation in
spherical coordinates is derived. Following a procedure introduced by
Maschke and Perrin, by supposing that the plasma temperature is a surf
ace quantity, we describe a two-parameter family of axisymmetric toroi
dal configurations. The equilibrium equation is analytically solved fo
r given hypotheses in such a way as to investigate the effect of plasm
a rotation on the magnetic field structure.
