ABSTRACT:
A flat electric motor comprises a rotor with a flat, permanent magnetic disc which is rotatable about an axis of rotation, and an electromagnetic stator with a stack of flat, electrically insulating supporting elements having first and second principal surfaces on which patterns of conductor tracks are provided such that there is formed a number of windings consisting of first and second coils arranged in a ring about the axis of rotation and which are formed by spirally extending conductor tracks on the first and the second principal surface of each supporting element. The coils which form part of one winding are electrically connected in series via connection tracks which a part of the conductor tracks, interconnections which extend between the first and second principal surfaces, and connection elements which connect connection tracks on different supporting elements of the stack to one another. The supporting elements of each stack are formed by successive parts of a support in the form of a strip of an electrically insulating foil, between each pair of successive supporting elements there is a folding line which extends transversely of the local longitudinal direction of the strip. In order to form the stack of supporting elements, the strip is folded along the folding lines and the connection elements are formed by connection tracks which cross the folding lines. Very reliable connection elements are thus formed at hardly any additional cost.
