ABSTRACT:
The production of electrical machines and more specifically to assembling the stator of a slotless electrical machine. The essence consists in splitting the process of assembling the slotless stator of an electrical machine into such production operations and in fulfilling these operations in such succession that it is possible to create an active distributed layer from separate coil groups beyond the yoke of the slotless stator being assembled and then to transfer simultaneously all coil groups of the assembled active distributed layer onto the surface of said yoke. The device for assembling a slotless stator of an electrical machine is provided with a bed frame, an assembling template movably installed on the bed frame and having a magnetizing winding, on which template coil groups are fixed in given relative positions by means of a magnetic field, a yoke holder stationarily installed on the bed frame, coaxially with the assembling template, with said yoke having a magnetizing winding with the contour of its opening corresponding to the outer contour of the yoke of the slotless stator under assembly, a former of head portions of coil groups, comprising two punches disposed at different sides of said yoke holder, coaxially therewith, and having a possibility for longitudinal reciprocal displacement in relation to said yoke holder.
