초록 ▼

A method and apparatus for forming a coreless armature winding for an electric machine, such as a motor, having two or more poles. A source of wire is revolved in a fixed orbit about a rotatable cylinder, the axis of this orbit being inclined with respect to the longitudinal axis of the cylinder. The wire is guided about first and second guide members positioned at opposite spaced apart locations on the surface of the cylinder. These guide members define the opposite ends of the coreless armature winding such that when the wire is wound thereabout, one complete turn is formed on the surface of the cylinder. The cylinder is rotated about its longitudinal axis in synchronism with the revolution of the wire, the cylinder being rotated by a predetermined angle corresponding to the pitch of the winding so that, as the wire continues to revolve, successive skewed turns are formed on the surface of the cylinder. The guide members are rotated as the cylinder rotates, and after a predetermined number of turns have been formed, the guide members are returned to their respective initial positions. Then, the foregoing operation is repeated until a complete armature has been formed. In one embodiment, the guide members are returned to their respective initial positions after each complete turn is formed. In accordance with another embodiment, the guide members are returned to their initial positions after a number of turns corresponding to a pole width have been formed.

A method of forming a coreless armature winding for an electric machine, comprising the steps of revolving a source of wire in a fixed orbit about a cylinder, the axis of said orbit being inclined with respect to the longitudinal axis of said cylinder; guiding said wire about first and second guide members positioned at opposite spaced apart locations on the surface of said cylinder and defining the opposite ends of the coreless armature winding so as to form one complete turn of said wire about said surface of said cylinder; rotating said cylinder about the longitudinal axis thereof in synchronism with the revolution of said wire, said cylinder being rotated by a predetermined angle corresponding to a pitch of the winding so that as said wire continues to revolve, successive skewed turns of said wire are formed on said surface of said cylinder; rotating said first and second guide member with the rotation of said cylinder; rotating said guide members relative to said cylinder for returning said first and second guide members to initial positions thereof after a predetermined number of turns have been formed repeating the aforementioned steps until the complete armature winding is formed; and removing said armature winding from said cylinder. Apparatus for forming a coreless armature winding for an electric machine, comprising: a revolvable source of wire; a rotatable cylinder, said source of wire being revolvable in an orbit about said cylinder, said orbit having an axis of revolution that is inclined with respect to the longitudinal axis of said cylinder; means for rotating said cylinder about the longitudinal axis thereof in synchronism with the revolution of said source of wire; first and second guide means disposed at spaced apart locations on the surface of said cylinder to define the opposite ends of said armature winding, said first and second guide means being rotatable with said cylinder, and said first and second guide means intercepting said wire as said source of wire revolves about said cylinder so as to establish respective double back points for each turn of wire; and means for rotating said first and second guide means relative to said cylinder in a direction opposite to the direction of rotation of said cylinder and through a predetermined angle, after a predetermined number of turns of said wire has been formed on said cylinder, to return said first and second guide means to respective initial positions to intercept said wire again.
