Abstract: An axial flux motor assembly (10) comprises a stack of first and second discs (20a, 20b) arranged alternately such that there is a gap allowing rotation between each disc (20a, 20b). The first disc (20a) is mounted on a rotatable shaft (40), while the second disc (20b) is fixed in position. The first and second discs (20a, 20b) each comprise sectors (200) of magnetic material arranged on a face of the disc (20a, 20b), between each of which sectors (200) is a radially-extending conductor (202) of a conductive path (201) for conducting electric current. The sectors (200) of magnetic material on the first and second discs (20a, 20b) are arranged at a constant angular pitch, but the pitch of the sectors of magnetic material on the first disc may or may not be the same as those on the second disc.
