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 circumference of the imaginary column at an angle of inclination with respect to the axis of rotation of the column. A further winding portion is wound at the other terminate face of the imaginary column along the circumferential 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 rotation 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.
