摘要： A pulling-up-type continuous casting apparatus that lets molten metal solidify while pulling up a drawing section for drawing the molten metal from a molten-metal surface of the molten metal held in a holding furnace, and thereby shapes the molten metal, includes means for applying a non-contact force to held molten metal, the held molten metal being molten metal that has been drawn from the molten-metal surface by the drawing section but has not solidified yet.

摘要： In a method for manufacturing a stator core, core steel plates each having a yoke part and teeth parts are sequentially formed and the core steel plates are laminated one on another to produce the stator core. This method includes forming a cut section extending in a radial direction in each of the core steel plates in the progressive press process so that the cut section is located in only one place in a circumferential direction.

摘要： There is provided a rotating electric machine capable of preventing a coolant from being retained at an outer surface of a rotor. This rotating electric machine includes a rotation shaft provided so as to be rotatable, a core body secured to the rotation shaft, a permanent magnet embedded in the core body, and an end plate provided so as to be opposed to an axial end surface of the core body. A first coolant channel is formed in the rotation shaft to allow a coolant to flow therethrough. A second coolant channel is formed between the end plate and the axial end surface of the core body to communicate with the first coolant channel. A partition wall that partitions the second coolant channel in a circumferential direction and a path wall that guides the coolant in the second coolant channel toward an outer peripheral edge region of the axial end surface where the permanent magnet is placed are formed inside the second coolant channel.

摘要： A stator structure which enables coils to be fitted over teeth while the circularity of the stator core and the parallelism between the end surfaces of the stator core are maintained. A stator structure is provided with: a stator core which is formed by stacking steel plates and which comprises a yoke and teeth; and coils which are fitted over the teeth so as to surround the teeth. A cut is formed only in one part of the yoke, and the cut is opened. Opening the cut allows the coils to be fitted over the teeth while the circularity of the stator core and the parallelism between the end surfaces of the stator core are maintained.
