PURPOSE: A hollow-cylindrical coreless winding is provided to generate the improvement in the stability of the overall coil by organizing the electric motor in multiple coils into a single stream. CONSTITUTION: The multiple coils in a single stream (2.1,2.2,2.3) are composed of multiple rotating units. The multiple rotating units are spirally rolled up on the surrounding areas of a winding mandrel. The multiple coils in a single stream are also overlapped with the roof tile mode. The coils include at least 2 phase windings (6,7,8). These coils are, then, rolled and wound around the continuous wires respectively. |
