<p>A conductor section for a stator core of a polyphase dynamo-electric machine. The stator core is provided with a series of elongated parallel slots for receiving respective conductor sections. The conductor section includes two parallel sides (6, 8) having a rectangular cross section and designed to engage the corresponding parallel slots in the stator core such that the two sides define a plane. Said conductor section further includes at least one conductor head (10) having a rectangular cross-section and linking two adjacent ends of the two parallel sides. The head has a U-shaped body when seen from above perpendicularly to the plane, and a sinuous body when seen in front view along said plane. The head has upper and lower opposite surfaces. The upper surface faces one side of the plane whereas the lower surface faces the opposite side of the plane. The conductor section advantageously enables the efficiency of a motor to be increased since the stator slot space factor is high, while at the same time enabling the sections to have small heads, thereby reducing motor weight and heat loss.</p> |
