Research on a permanent magnet assisted synchronous reluctance machine with hybrid excitation

In this paper, the results of simulation tests of a hybrid excited permanent magnet machine operating in various states have been presented. The characteristic feature of this machine is a presence of magnetic barriers inside the rotor. Structurally, this machine combines advantages of the PMa-SynRM machine (Permanent Magnet assisted Synchronous Machine) and a wound synchronous machine. The paper presents the voltage and torque characteristics as a function of the current in the stator and the DC control coil. Additional selected results of experimental studies are also shown.
