Abstract: Disclosed are a rotor and a permanent magnet motor. The rotor includes a rotor core, at least two first permanent magnets and at least two second permanent magnets. A coercivity of each first permanent magnet is different from a coercivity of each second permanent magnet, the at least two first permanent magnets and the at least two second permanent magnets are arranged in an axial direction in magnetic steel slots of the rotor core. One of the first permanent magnets and one of the second permanent magnets are arranged to be connected in series in a radial direction of the rotor core in one slot to form a permanent magnet pole. A consequent pole is formed between every two adjacent permanent magnet poles, and the permanent magnet pole forms a magnetic circuit passing through the consequent pole.

Abstract: A dual-layer linear cross belt sorting system is provided, including a package supply table, a sorting loop, a platform, sliding chutes and a scanning device. The sorting loop is of a closed-loop and dual-layer linear conveying structure in a vertical direction, and the sorting loop includes sorting trolleys connected along a single queue, two sets of dual-layer rails formed by connecting bent rails located at two ends and straight rails located at upper and lower layers to each other by an internal welding, a driving component and a tensioning component. The driving component and the tensioning component constitute a transmission structure of the sorting loop and are located at two ends of the sorting loop respectively.

Abstract: The present disclosure is related to a self-starting synchronous reluctance motor rotor, a motor and a compressor. The self-starting synchronous reluctance motor rotor includes a rotor core; the rotor core is provided with a plurality of slit grooves; both ends of each of the slit grooves are respectively provided with a filled groove; a first end of the filled groove is provided adjacent to each slit groove, and a second end of the filled groove extends outwards parallel to the d-axis of the rotor core; the second end of the filled groove is provided with at least one bevel edge, so that when the d-axis magnetic flux of the rotor core enters a stator along channels formed at the bevel edges, no abrupt change occurs to the magnetic flux.

Abstract: A cross belt sorting trolley is provided, including an upper conveying unit and a lower frame. A folding plate is horizontally mounted on a side of each side plate. A first bending connecting plate or a second bending connecting plate is vertically connected to the side of each side plate. The folding plate is an integral horizontal plate-like component. A plurality of uniform circular arc-shaped sections are arranged on an outer side edge of the folding plate. The plurality of uniform circular arc-shaped sections of folding plates on both sides of the cross belt sorting trolley engage with each other. A plurality of folding plate fixing plates are mounted on a side portion of each side plate. The plurality of folding plate fixing plates are provided with bending portions. Side portions of the plurality of folding plate fixing plates are fixedly connected to side plates.
