Abstract
Stator of a direct current electrical machine comprises a support structure (1) defined by a pair of frame members (4) and beams (2), the latter being disposed around the center line (3) of the stator with the ends thereof affixed to the frame members (4), and a magnetic circuit (7) having a yoke (8) and pole pieces (9 and 10) secured to the yoke (8). The yoke is in the form of a single continuous band coiled into a cylindrical spiral, each turn of the spiral embracing by a wider side thereof all the beams (2) of the support structure (1).
Claims2
A direct current electrical machine stator comprising a support structure having beams disposed around the longitudinal center line of the stator, a magnetic circuit incorporating a yoke adapted to cooperate with support beams, and pole pieces affixed to the yoke, characterized in that the yoke (8) is in the form of a continuous band coiled into a cylindrical spiral with each turn of the spiral embracing by a wider side thereof all the support beams (2) of the support structure (1), the support structure (1) further comprising a pair of frame members (4) positioned at the bases of the cylindrical spiral and having ends of the support beams (2) of the support structure (1) secured thereto.
