Abstract: The present invention relates to a shaft-embracing permanent magnet inter-shaft glued stator structure of a high-speed motor; the structure is a shaft-embracing permanent magnet integrated structure; the rotor structure comprises a permanent magnet (2), an output shaft (1) which is connected with one end of the permanent magnet (2) and embraces one part of the permanent magnet (2), and a rear shaft (4) which is respectively connected with the other end of the permanent magnet (2) and the output shaft (1), used for embracing the other part of the permanent magnet (2), and connected with the output shaft (1) to form a sealing mechanism of the permanent magnet (2). Compared with the prior art, the present invention has advantages of good electro-magnetic performance, high reliability, high productivity and good concentricity.

Abstract: The present invention relates to a hollow cup winding capable of reducing distribution coefficient, comprising N phases of windings, where each phase of the windings consists of k (360/k/N)° coil units and the k coil units constitute of backing coil assemblies and forward coil assemblies. Compared with the prior art, the present invention has the advantages of improving motor performance and of being highly universal.

Abstract: The present invention relates to a centrally-distributed coreless winding, comprising staggered conductors, normal conductors and winding taps, wherein the staggered conductors are concentrated in the middle of the winding, the normal conductors are distributed on both sides of the staggered conductors and the winding taps are located at both ends of the normal conductors, the density in the middle portion of the winding is greater than that of the normal conductors. Compared with the prior art, the invention effectively raises the back electromotive force (BEMF) of the coreless motor and further improves the performance of the motor.
