Abstract: Herein disclosed is an ironless rotor winding for a cup-shaped electric motor. A winding portion is wound through one terminate face of an imaginary column. Another winding portion is wound onto the periphery of the imaginary column at an angle of inclination with respect to the axis of revolution of the column. A further winding portion is wound at the other terminate face of the imaginary column along the peripheral edge of the column. Thus, the overall rigidity of the ironless rotor winding can be increased. In an alternative, the winding portion wound onto the circumference of the imaginary column at an angle of inclination with respect to the axis of revolution is composed of a first segment having a smaller angle of inclination, and a second segment having a larger angle of inclination. Herein also disclosed are method and machine for making the such ironless rotor winding.

Abstract: 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.

Abstract: A method of manufacturing a cup-shaped coil assembly is described which employs a coil bobbin of a special design. The bobbin comprises a cylindrical member, a disc connected with one end of the cylindrical member to close it, a cap member detachably fitted into an opening in the other end of the cylindrical member, and a shaft disposed in alignment with the axis of the cylindrical member and having its one end attached to the disc and its other end slidably extending through the cap member. The method comprises the steps of assembling a coil bobbin in the manner mentioned above, and forming a coil around the bobbin by a skewed winding of wire, pressing the cap member into the cylindrical member, diametrically enlarging an opening formed at one end of the coil, and removing the cap member from the coil formed.

Abstract: In each coil (10), between a first radial section formed by a winding-start section (10a) and a second radial section formed by a winding-end section (10b) of a winding (10A), the circumferential lengths of the winding lap sections formed by said winding change in a continuous or stepped manner. For a first coil, the sequences within two slots (22) of the winding constituting the first coil are reversed with respect to one another by a twisted section (10d) between a first coil end (12a) and a second coil end (12b) of the first coil. The first coil and next second coil form a lap winding in which the twisted sections of the first and second coils are three-dimensionally entwined. The lap winding of said twisted sections continues for the third and subsequent coils, and the first coil end and the second coil end of each coil are continuous without spaces at the end surfaces of a core (20).
