Performance Analysis of SynRel and PMARel Motor Prototypes with Additive Manufactured Rotors

This paper deals with the use of Additive Manufacturing technology for the fabrication of two rotors for synchronous motors. First, a Design of Experiment is presented to highlight the importance of fine tuning and optimization of process parameters in order to be able to produce high-quality printed cores both structurally and electromagnetically. Thereafter, two motor prototypes were fabricated. A Synchronous Reluctance motor with a printed rotor was simulated and experimentally tested. Finally, such a design was upgraded to a Permanent Magnet Assisted Reluctance motor, also with a printed rotor and again simulated and tested.
