    摘要: A rotor core has first and second magnet insertion holes along an outer circumference, and first and second slits along an inner circumference. The first and second slits have first and second facing portions facing each other. The first facing portion has a first inner end and a first outer end. The second facing portion has a second inner end and a second outer end. An inter-slit portion is provided between the first and second facing portions and is defined by a first straight line connecting the first and second inner ends and a second straight line connecting the first and second outer ends. In a radial direction of the rotor core, a minimum distance D1 from the inner circumference to the slits, a minimum width W1 of the slits, and a length W2 of the inter-slit portion satisfy at least one of D1

    摘要: A rotor is connected to a shaft member and rotates about a central axis. The rotor includes a shaft hole having at least part of the shaft member disposed therein; and flow paths disposed around the shaft member and penetrating the rotor in a direction parallel with the central axis. Each flow path has a first surface facing outward in the radial direction; a second surface disposed outward of the first surface in the radial direction and facing the first surface; a third surface connecting the first and second surfaces at one end in a rotational direction about the central axis; a fourth surface connecting the first and second surfaces at the other end in the rotational direction. The condition C

    摘要: A rotor includes a rotor core having a magnet insertion hole and a permanent magnet provided in the magnet insertion hole. The rotor core has a slit on an outer side of the magnet insertion hole in a radial direction of the rotor core. The permanent magnet is magnetized by placing the rotor so as to face a tooth around which a winding is wound, rotating the rotor in a first rotating direction from a rotational position where a center of the magnet insertion hole in a circumferential direction of the rotor core faces a middle portion between both ends of the winding in the circumferential direction and supplying electric current to the winding, and rotating the rotor in a second rotating direction opposite to the first rotating direction from the rotational position and supplying electric current to the winding.

    摘要: An electric motor includes a stator and a rotor including a permanent magnet and an electromagnetic steel sheet. The electromagnetic steel sheet includes a magnet insertion hole, a first outer peripheral surface including an inter-pole part of the rotor, a second outer peripheral surface including a magnetic pole center part of the rotor, a first slit elongated in a circumferential direction of the rotor, and a first portion formed between the first slit and the magnet insertion hole. A distance from the first outer peripheral surface to the stator is larger than a distance from the second outer peripheral surface to the stator. The electric motor satisfies θa
