Rotor And Electric Motor
Abstract: A rotor core provided in the rotor has a plurality of magnet embedding holes (12) in which plate-shaped permanent magnets (13) are embedded at intervals in the circumferential direction of the rotor core; salient pole portions (11) formed on the outside of the permanent magnets (13) in the radial direction of the rotor core; gap portions (14, 15) extending from both ends of the permanent magnet (13) in the circumferential direction of the rotor core toward the outer peripheral surface of the rotor core; notch grooves (16, 17) formed by cutting out a part of the outer peripheral surface of the rotor core; and a bridge portion (26) formed between the outer peripheral surface and the gap portion (14, 15). The notch grooves (16, 17) are arranged so that the bridge portion (26) is sandwiched between the notch groove (16, 17) and the gap portion (14, 15), and a notch minimum outer diameter portion where the distance from the rotation center (O) of the rotor core is minimal is formed on a plane orthogonal to the rotation axis of the rotor core. The notch minimum outer diameter portion is located on the center (D) side of the salient pole portion (11) with respect to the gap portion (14, 15) in the circumferential direction of the rotor core.
