Electromagnetic Design of a Novel Asymmetrically Stagger Hybrid Excitation Synchronous Machine

The structure characteristics and field-control principle of a novel asymmetrically stagger hybrid excitation synchronous machine (ASHESM) were introduced. The theory and method of electromagnetic design for ASHESM were discussed. A 2 kW 8-pole prototype were manufactured to verify the design method. The experiment for the different on-load field-control capability of the ASHESM was carried out. The experimental results indicate that the flux of this type of machine can be easily adjusted in a wide range with a relatively small field current.
