Title: Feasibility Study of a Hybrid Excited Claw-Pole Alternator
Keywords: claw-pole alternator, hybrid excitation

Abstract: The paper studies the feasibility of a hybrid excited claw-pole alternator, using an analytical method for calculation of magnetic flux in the machine air gap. This study will serve as a preliminary calculation to prove or disprove the feasibility and show the advantages and the disadvantages of the proposed topology. The proposed method permits to assess the area of the permanent magnet that is required to obtain a desired voltage at the machine’s terminals at a required speed and to properly size the additional excitation winding. The advantages and disadvantages as well as possible applications are discussed.
