Latest Patents

Kawanami holds a patent for a novel dynamo-electrical machine. This invention is designed to inhibit an increase in the height of a coil end positioned toward a turn portion. It also improves the cooling performance around the turn portion of a segment coil. The segment coil consists of a first linear portion, a second linear portion, and a turn portion that includes a top portion. The first linear portion is inserted into a specified slot, while the second linear portion is placed in a different slot. The turn portion extends from one end face portion of a stator core toward the outside of the axial direction of the stator core, connecting the first and second linear portions. The linear portions of multiple segment coils are inserted and layered in the slots from the inner periphery to the outer periphery in the radial direction. A bent portion is formed between each of the linear portions and the turn portion of the segment coils layered in the radial direction, tilting the top portion of the turn portion toward the end face of the stator core.
