Definitions

  • the present invention relates to the field of stator winding machines, and precisely it relates to a method for wire termination on outwardly spooled multi-pole stators. Furthermore, the invention relates to an apparatus that carries out this method.
  • Outwardly spooled multi-pole stators are known, formed by a substantially star-shaped stack of sheets featuring a plurality of poles extending from a tubular core.
  • the stators of this type are suitable for coupling with an inner concentric armature or outer ring armature. They are common in brushless motors.
  • the peripheries of the poles, or pole extensions form substantially a cylinder with a plurality of slits parallel or oblique with respect to the axis of the stator.
  • the peripheries of the poles are connected to the core by means of pole walls that define corresponding grooves, accessible through the slits.
  • the grooves have to be filled with insulated lead wire, by creating coils spooled about the pole walls.
  • winding machines exist having a winding arm, or flier, which rotates causing the wire to follow a circular trajectory and thus spooling the coil about each pole wall.
  • the wire follows the circular trajectory while it is guided in the slits by means of special winding shrouds.
  • the shrouds are normally of two types, usually enough to wind the most common outwardly spooled multi-pole stators: a couple of lateral guiding plates, which form substantially a channel that aids the wire to enter the slits; hits are thus avoided of the wire against the edges of the poles adjacent to the pole being wound; a shroud that allows the wire to overtake the pole making substantially a double slide guide that deviates the wire from its own circular trajectory and brings it to wind about the pole wall.
  • the shroud normally is mounted on a support shaft, that is co-axial to the flier and is movable towards/away from the axis of the stator, for laying uniformly the wire helically about the pole wall. It can be either a whole block, or formed by two symmetrical mobile halves.
  • the flier at winding, rotates about the support shaft of the shroud in order to have its free end needle that moves in orbital position both with respect to the pole being wound and to the shroud that guides the wire in the grooves.
  • Every portion of wire wound about one or more poles has at least two ends.
  • the ends have to be inserted into terminals.
  • the terminals in turn, when the motor is assembled, are connected to the current supply circuits for operation of the motor.
  • the terminals are integrated in a terminal board, which is a body of plastic material that insulates axially the stack of sheets that form the ferromagnetic core of the stator.
  • the termination in outwardly spooled multi-pole stators, which allow a winding by means of a flier, is carried out in the way indicated hereinafter: before winding each pole, or plurality of in-phase poles, the flier cooperates to put the wire ends in the terminals with a termination apparatus, at the end of winding of each pole or several poles, the outgoing wire is kept stretched by the flier so that the termination apparatus can catch it, cooperating with the flier for carrying out the termination, and finally cutting the wire close to the terminal, gripping the end of the wire that comes from the flier and awaiting the start of next winding step; in the two termination steps as above described, the movement of the flier is programmed with fractions of clockwise and/or anticlockwise rotation and with approaching motion of the stator, for cooperating with the termination apparatus and causing the wire to follow a path that approaches the terminal.
  • the termination apparatus comprises tools like lead pulls, cutters, clamps, which move in a direction which, normally, is orthogonal to the axis of the stator.
  • the termination apparatus can be arranged in the easiest way for catching the ends. Instead, when winding stators with external poles, with a flier, the position of the termination tools interferes with the movement of the flier, and they are therefore complex to arrange.
  • the flier moves the wire must be blocked in the terminal, to avoid that it can move away from the terminal at winding in the first coils.
  • the movement of the flier keeps the wire stretched while the termination is carried out.
  • the wire can be blocked, in most of cases, at a suitable moment with a special instrument on board of the machine and that engages the terminal, approaching orthogonally to the axis of the stator.
  • a further problem is that, when introducing an end of wire in a terminal, the end protrudes of a certain amount beyond the terminal, and has to be trimmed. Thus, an off-cut wire portion would fall at the base of the machine or, where possible, in a container located underneath. This has the risk that the off-cut portion can sometimes jam into the machine or remain accidentally wound in the stator, causing in both cases a serious drawback.
  • Another object of the present invention is to provide a terminating device that moves without obstructing the movement of the flier during the termination.
  • a method for wire termination on outwardly spooled multi-pole stators wherein the stators are formed by a core of ferromagnetic sheets, having an axis and a plurality of poles that radially extend defining grooves between them, and by a terminal board that covers in part the core and has a plurality of terminals, wherein the wire is wound about the poles distributed by a rotatable arm and guided by shrouds that move radially with respect to the stator overlapping the respective polar extension, and wherein before and/or after winding wire termination operations are provided of the wire in the terminals with the aid of the rotatable arm, the operations of terminating comprising steps of catching, moving, introducing in the terminals and cutting a portion of wire, has the characteristic that the steps of catching, moving, introducing and cutting the wire occur by means of a single multifunctional instrument having an axis parallel to the axis of the stator, capable of carrying out

  • the step of introducing the wire comprises, before starting winding step, a step of creating a bridge of wire between a clamp and a taker-in element, and a step of introducing the wire bridge in the terminal by translating the bridge parallel to the axis.
  • the step of creating the bridge can be carried out by rotating the clamp and the taker-in element about the axis.
  • the step of cutting the wire is carried out by bringing a blade parallel to the axis up to intersecting the wire, kept by a clamp.
  • the step of cutting the wire being associated to a movement of folding the portion of cut wire protruding from a terminal to bend along the terminal side before the start of winding.
  • the portion of cut wire bent along the terminal side is kept pressed against the terminal at least during the first winding phases.
  • the portion of cut wire is kept pressed elastically by an element associated to the shroud that extends from the shroud in a direction orthogonal to the axis.
  • the step of catching the wire, when after winding a portion of wire is stretched between the flier and a spooled coil is carried out by translating a clamp parallel to the axis up to a predetermined position, opening the clamp, rotating the flier until the stretched wire portion does not intersect the predetermined position, closing the clamp.
