Abstract: The present invention discloses a polypeptide and application thereof. By modifying oxyntomodulin (OXM), hybridizing OXM with a peptide sequence of Exenatide, including enabling the polypeptide to be resistant to DPP-4 enzyme degradation through amino acid modification, and conjugating fatty acid chains at the same time, an OXM hybrid peptide having longer pharmacologic action time and better weight losing effects is obtained. Synthesis of a target polypeptide is fast realized by an orthogonal protection strategy solid-phase synthesis method, and a crude product is purified and freeze-dried to obtain the OXM hybrid peptide.

Abstract: The present disclosure discloses a stator assembly and motor. The stator assembly comprises a stator core and a multi-branch rectangular conductor winding, an even number of stator slots are provided on an inner circumference of the stator core, and each of the stator slots is divided into multiple layers for accommodating rectangular conductors. The multi-branch rectangular conductor winding is provided in the stator slots, and the multi-branch rectangular conductor winding comprises B number of parallel branches, and B is an integer multiple of 4. The number of slots per phase per pole, Q, of the stator assembly is an odd number, and Q and B satisfy a relationship that both (Q+1)*2/B and (Q?1)*2/B are integers.

Abstract: A rotor structure of a magnet motor includes a rotating shaft and an iron core on the rotating shaft. Magnet grooves are disposed inside the iron core along a circumferential direction with a magnet provided therein. A distance between an edge line of the magnet groove close to a circumferential edge of the iron core and the circumferential edge of the iron core varies so that a width of a flux barrier formed varies. One end of a long side of the magnet groove close to the circumferential edge is formed with an anti-demagnetization groove communicating with the magnet groove, and an edge line of the anti-demagnetization groove tilts toward the circumferential edge of the iron core. Process slots are provided between the magnet grooves and the circumferential edge of the iron core that are used to increase a salient rate and reluctance torque of the motor.

Abstract: A stator structure and a flat wire motor are provided. The stator structure comprises a stator core, stator windings and an avoidance layer. The stator core has an inner cylinder cavity, and a plurality of iron core slots arranged at intervals in a circumferential direction on an end face of the stator core. The iron core slot is communicated with the inner cylinder cavity via a slot opening. The stator windings have a plurality of layers of flat wire conductor wound in the iron core slots. The avoidance layer is located between the slot opening and a first layer of flat wire conductor in a radial direction of the stator core.
