Permanent Magnet Alternator

A permanent magnet alternator is an electrical generator making the conversion from mechanical energy to AC electrical energy. The permanent magnet alternator is by principle a multiphase AC synchronous machine and more particularly a 3 phase machine delivering a balanced system of AC voltages and currents, in which both statoric and rotoric magnetic fields are rotating synchronously that is to say at the same speed. The excitation of the permanent magnet alternator or inductor is made by permanent magnets bonded to the rotor. There are structures of permanent magnet alternators with internal rotor and external stator on one hand and structures of permanent magnet alternators with internal stator and external rotor on the other hand. However, the permanent magnet alternators with external stator are more performing in terms of power-to-weight and torque-to-weight because the cooling of statoric windings is easier when the stator is in contact with the air. The ALXION STK permanent magnet alternators have external stator and internal rotor and are excited by strong rare earth permanent magnets.
