摘要： A motor for a surgical instrument includes a rotor and a stator. The rotor includes a shaft and a magnet. The stator includes (i) a cavity in which the rotor is disposed, and (ii) a coil assembly. The coil assembly includes multiple phase sets. The phase sets include multiple sets of wires. Each of the phase sets includes multiple coils and corresponds to a respective one of the sets of wires. The coils in each of the phase sets are at respective positions about the rotor. One of the sets of wires includes at least three wires. The stator causes the rotor to axially rotate a surgical tool of the surgical instrument based on current received at the sets of wires.

摘要： A stator structure of a vehicle motor includes a stator core assembly and a plurality of coil assemblies composed of flat wires. The stator core assembly includes an annular portion and a plurality of tooth portions. The tooth portions extend from the annular portion in a radial direction toward a center of the stator core assembly. Each coil assembly is configured around a corresponding tooth portion. Each coil assembly includes a first flat wire and a plurality of second flat wires that are electrically connected in parallel. The first flat wire is radially stacked and wound around the corresponding tooth portion. The second flat wires are arranged radially adjacent to the first flat wire and are electrically connected in series to the first flat wire. The second flat wires are alternately stacked and radially wound around the corresponding tooth portion.

摘要： A method for producing a coil includes winding a wire in order to produce a wound coil, and stretching the wound coil from an initial state into a stretched state with an increased spread. The method includes providing the wound coil, in the stretched state, with a coating, and transferring the wound coil from the stretched state back into a state of smaller spread.

摘要： The invention relates to a method for producing a helical metal body (1, 1′), in particular made of aluminum or an aluminum alloy. A blank is first produced in a primary shaping process, a metal forming process, or in a removal process, in particular a machining process, and one or more recesses (100, 101, 201, 202, 203) are then introduced into the blank using a removal process, said recesses defining a circumferential coil, the adjacent windings thereof being mutually spaced, in particular electrically insulated from one another.

摘要： In one embodiment, a stator coil that includes a first turn with two or more strands is provided. The first turn includes first and second opposite sides, a coil termination at a first end of the first turn and an inversion region disposed at a second end, opposite the coil termination. The stator coil also includes at least one additional turn with two or more strands. The at least one additional turn includes first and second opposite sides, and an inversion region located adjacent to the inversion region of the first turn. The first and second sides of the first turn are inverted relative to the first and second sides of the at least one additional turn outside their respective inversion regions.
