  • Publication number: 20240204595
    Abstract: A rotor includes a columnar rotor core, having multiple core plates laminated in a thickness direction and a magnet insertion hole extending in an axial direction; and a magnet inserted in the magnet insertion hole. The core plates have multiple first core plates. The first core plates are continuously laminated in the axial direction. Each of the first core plates includes a contact portion and a deformation permitting portion. The contact portion defines a portion of an inner surface of the magnet insertion hole and contacts with the magnet. The deformation permitting portion is located on an opposite side of the magnet with the contact portion in between when the first core plates are viewed in the thickness direction, and permits deformation of the contact portion. Multiple contact portions in the first core plates overlap at least partially when the rotor core is viewed in the axial direction.

  • Publication number: 20240113577
    Abstract: A rotor includes stacked core plates, a hole, and a magnet inserted into the hole. A holding core plate has a through hole as part of the hole, a protrusion protruding inwardly from an inner surface of the through hole and being in contact with the magnet, and a displacement permission portion located in an opposite direction to a protrusion direction of the protrusion and permitting displacement of the protrusion in the opposite direction. The rotor includes at least one of a magnet-side chamfered portion in which the front side edge portion of the magnet is chamfered or a protrusion-side chamfered portion in which the tip end edge portion of the protrusion is chamfered. A sum of lengths of the magnet-side and protrusion-side chamfered portions is equal to or longer than a length of the protrusion in the protrusion direction as the rotor is viewed from the axial direction.
