A small PMDC motor having a wound salient pole armature with three or five salient poles, wherein the armature has a winding guide disposed within a winding tunnel formed between adjacent salient poles of the armature and arranged to divide the radially inner portion of the winding tunnels; characterised in that: the winding guide comprises a vane located within each winding tunnel, each vane extending along the winding tunnel and extending radially outwardly from a radial inner surface of the winding tunnel, whereby windings wound about the adjacent salient poles of the armature are restrained from entering into the opposite inner portion of the winding tunnel, wherein the salient poles are substantially T-shaped having a radially extending spoke extending from a central region and a circumferentially extending pole head forming a pole face facing radially outwardly, each pole head extending between circumferentially spaced tips, a winding gap being formed between tips of adjacent pole heads and the winding tunnels being formed between adjacent poles where the windings are located and being open radially through the winding gap, wherein the vanes extend along a radial plane, bisecting the winding tunnel and projecting towards the winding gap and have a radial height sufficient to separate adjacent windings within the winding tunnels, and the radial height of each vane is either: substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the leading tip of a pole head to the trailing tip of an adjacent pole head, which does not delimit the same winding tunnel, in the case of having three salient poles; or substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the tip of a pole head to the root region of the spoke of the adjacent pole that delimits the same winding tunnel, in the case of having five salient poles. the winding guide comprises a vane located within each winding tunnel, each vane extending along the winding tunnel and extending radially outwardly from a radial inner surface of the winding tunnel, whereby windings wound about the adjacent salient poles of the armature are restrained from entering into the opposite inner portion of the winding tunnel, wherein the salient poles are substantially T-shaped having a radially extending spoke extending from a central region and a circumferentially extending pole head forming a pole face facing radially outwardly, each pole head extending between circumferentially spaced tips, a winding gap being formed between tips of adjacent pole heads and the winding tunnels being formed between adjacent poles where the windings are located and being open radially through the winding gap, wherein the vanes extend along a radial plane, bisecting the winding tunnel and projecting towards the winding gap and have a radial height sufficient to separate adjacent windings within the winding tunnels, and the radial height of each vane is either: substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the leading tip of a pole head to the trailing tip of an adjacent pole head, which does not delimit the same winding tunnel, in the case of having three salient poles; or substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the tip of a pole head to the root region of the spoke of the adjacent pole that delimits the same winding tunnel, in the case of having five salient poles. substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the leading tip of a pole head to the trailing tip of an adjacent pole head, which does not delimit the same winding tunnel, in the case of having three salient poles; or substantially equal to the height of a radial line extending through the vane and being cut by a line extending from the tip of a pole head to the root region of the spoke of the adjacent pole that delimits the same winding tunnel, in the case of having five salient poles.
