Synchronous machine, has permanent magnets with alternating polarities at rotor circumference, where part of maximum needed air gap-flux density is excited by permanent magnets coercive force and remaining part is excited by ampere-turns
The machine has a multi-phase alternating current coil, and permanent magnets (DM) that are arranged with alternating polarities at the circumference of a rotor (L) of the machine. A part of maximum necessary air gap-flux density is excited by coercive force of the permanent magnets and the remaining part of the air gap-flux density is excited by ampere-turns. The ampere-turns run synchronously with the rotor and act in the magnetic longitudinal axis of the pole formed by the permanent magnets.
