-This paper presents the design and performance comparison of a conventional claw-pole machine with a permanent magnet based claw-pole machine for automotive application. The magnets are placed in the inter-claw region to decrease the leakage flux and to supply increased magnetic flux in the machine. It has been observed that with the addition of permanent magnets weighing only a few grams, there is a significant increment of more than 22% in output power of the machine. The geometric dimensions of magnets were also varied to verify their effects on performance and it has been observed that with the increase in magnet weight there is a non-linear increment in torque of the machine.

“…Brushless excitation generators exhibit several key features, such as high reliability, easy maintenance and so on [1][2][3][4][5]. Many methods have been studied to realise brushless excitation, such as doubly salient generators, claw-pole generator and so on [6][7][8][9][10][11][12][13][14][15]. Most of the above-mentioned generators are still at the research stage.…”

This paper proposes a novel integrated brushless excitation method (IBEM) for a rotor-excited generator. IBEM is applied to a rotor-excited hybrid excitation synchronous generator (HESG) to realise brushless excitation while the key features of the rotor-excited generator are maintained. The new generator is referred as IBE HESG here. The stator excitation windings are buried in the stator slots. The static excitation field is established in the air gap when there is dc excitation current in the stator excitation windings. The three-phase armature coils of the rotor induce the static excitation field and provide the dc excitation current for the rotor excitation windings via a rotating rectifier. The operating principles are discussed theoretically. The magnetic field distribution and the operating characteristics are studied by finite-element analysis. The no-load, external, regulation and excitation characteristics are analysed. Compared with the brush excitation HESG, the rotor excitation current is able to meet the requirement and the output voltage is conveniently regulated by the stator excitation current. Finally, a 1.5 kVA prototype is fabricated to test the operating characteristics of IBE HESG. It demonstrates that the brushless excitation is realised and the output voltage is regulated by the stator excitation current.
