The authors discuss an axisymmetrical pure rotating, force-free and stable self-consistent pulsar model. They suggest that the pulsar does not need to be corotating. They also consider the inertia effects in building a noncorotating pulsar model with some parameters, which can be determined according to the system's stable condition. If there is no magnetic radiation, under the stable condition, the model is a corotating one. Its space charges are distributed within a definite distance from the rotating axis. In the case of a small angle between the rotating axis and the magnetic moment, magnetic radiation is allowed. In fact, a pulsar is a nonequilibrium system with a minimum entropy production as its stable condition. From this one can obtain an exact noncorotating model with radiations which have two parts: magnetic radiation and bremsstrahlung radiation. The bremsstrahlung radiation is due to collisions between electrons and protons in the pulsar crust. In the case of an arbitrary angle between the rotating axis and the magnetic moment, this result is also correct, except for different rotating velocity functions.
