    摘要： The present disclosure discloses a rotor of an induction motor comprising a rotor body (1), alternating rotor teeth (2) and rotor slots (3) arranged along a circumference of the rotor body (1), and a plurality of grooves (4) provided at an end of the rotor teeth (2) or a plurality of voids (5) provided within the end of the rotor teeth (2) that are provided symmetrically about a center line (10) of the rotor teeth (2). The rotor and the induction motor having the rotor of the present disclosure can, for example, reduce the radial force of the stator caused by the slotting effect by about 50%. Therefore, the user's comfort can be greatly improved, while the efficiency of the induction motor can be improved, and the life of the induction motor can be prolonged.

    摘要： A rotor includes: a cylindrical rotor core fixed to an outer peripheral side of a rotary shaft rotatable about an axis center, the rotor core including multiple first slots arranged at intervals in the peripheral direction of the rotor core and penetrating the rotor core in the axis direction of the rotary shaft, and multiple second slots formed at an inner position of the rotor core with respect to the first slots, arranged at intervals in the peripheral direction of the rotor core, and penetrating the rotor core in the axis direction of the rotary shaft; and a secondary conductor including multiple conductor bars arranged in the first slots and the second slots, and a pair of ring-like end rings arranged at opposite end surfaces of the rotor core and connecting end portions of the multiple conductor bars.

    摘要： A laminated core can be contained in a rotor and/or in a stator and include at least one first sheet metal part assembly and at least one second sheet metal part assembly. The two sheet metal part assemblies are arranged alternately lying one against the other in a stacking direction. Every first sheet metal part has first teeth projecting from a connecting part radially relative to the axis of rotation. Correspondingly, every second sheet metal part has second teeth projecting from a second connecting part. The first teeth extend from the axis of rotation at a distance different from how far the second teeth extends from the axis of rotation to form a step to mesh the rotor with an associated stator and increase the air gap between them without increasing dimensions of the laminated cores in the stacking direction.

    摘要： A tubular body for an electrical machine is provided. The tubular body comprises a curved surface area, a first tooth and a second tooth. The tubular body is arrangable with respect to a further tubular body such that one of the tubular body or the further tubular body is rotatable with respect to the other one around a rotary axis. The first tooth and the second tooth extend from the curved surface area along a radial direction with respect to the rotary axis, wherein the first tooth and the second tooth are spaced apart from each other along a circumferential direction around the rotary axis. The first tooth comprises a first side wall facing a second side wall of the second tooth, wherein the first side wall comprises a first section which is parallel to the second side wall such that a circumferential distance between the first section and the second side wall is constant along the radial direction.
