Permanent magnet electrical machine inductor

The invention refers to a heteropolar inductor of a synchronous machine with permanent magnets made out of ferrite or other hard magnetic materials, where, in order to achieve high values of magnetic induction in the gap, the pole pieces [2], which are fixed rigidly to the magnetic yoke [1], are bordered on all sides except for the side facing the gap, by the permanent magnets [5 and 6] arranged tangentially and radially, respectively, as well as by the front permanent magnets [7] and the intermediary ones [9], with the magnetic rings [8 and 10]. The magnetising direction is set so that the field lines for all magnets adjacent to the pole pieces corresponding to a pole, will have the same direction.
