The study develops and experimentally validates a magnetic equivalent circuit for a claw‑pole alternator with stator‑mounted DC excitation, replacing the conventional rotor‑mounted winding. The MEC models both no‑load and loaded armature behavior, incorporates magnetic saturation, is solved via Newton‑Raphson, and is validated against prototype measurements. Eliminating the brush‑ring system yields significant cost, size, and reliability advantages, and the MEC predictions closely match experimental results.
We describe the development and the experimental validation of a magnetic equivalent circuit (MEC) of a new claw pole alternator where the DC-excitation winding is located in the stator (CPAES), rather than in the rotor in conventional claw pole alternator. Thus, we discarded the brush-ring system and achieved crucial cost, compactness, and reliability benefits. The proposed MEC treats both no-load and loaded armature operations. It also accounts for the saturation of the magnetic circuit. We numerically solve the established MEC using the Newton-Raphson algorithm. We validated the established MEC by considering experimental tests carried out on a prototype of the CPAES. We found that the results yielded by the proposed MEC and those given by the experimental tests are in good agreement.
