Abstract
The invention relates to a nested winding for a slotless motor. The nested winding is formed by inner and outer windings which are nested together and have different inner and outer diameters, wherein the number of the inner and outer windings is n, same-phase coils are connected in parallel or in series, and the number n of the nested inner and outer windings is equal to or greater than two. Compared with the prior art, the nested winding has the following advantages: a potential difference between the coils connected in parallel can be effectively reduced, and accordingly, the loss of the winding is reduced, and the high-speed operating performance of the motor is improved.
