<p>A multi-channel axial-flux wound-field synchronous machine 100 includes an even number of stators 110 and a plurality of field-excitation windings 120, each field-excitation winding being associated with one of the stators 110. The machine 110 also includes an exciter 146 to feed all of the plurality of field-excitation windings 120. Electrical connections between the exciter, the rotary power electronic unit and the field windings 120 are made though the hollow shaft 160. A method of assembling a multi-channel axial-flux wound-field synchronous machine 100 is described. Two or more stators may be connected in parallel to provide a redundant power supply or each of the stators may provide an independent power supply. The exciter may be single or polyphase and the stators 110 each act as polyphase armature systems. For example arrangements with 2,4 or 6, channels may provide 1,2 or 3 redundant power supplies. The machine may supply power to aircraft or vehicle essential systems such as aircraft fuel pumps</p> |
