The invention provides a rotating motor capable of suppressing performance degradation and reducing eddy current loss of a rotor, and an elevator traction machine system including the rotating motor.This rotating motor (100) is provided with: a rotor (1) and a cylindrical stator (2), wherein the rotor has a rotor core (3), a plurality of permanent magnets (5), and a rotating shaft (8); the cylindrical stator (2) is provided on the outside in the radial direction of the rotor (1). On a surface of the rotor core (3), groups of a plurality of permanent magnets (5) arranged in the axial directionand in contact with each other are arranged side by side in the circumferential direction. The portions where the plurality of permanent magnets (5) arranged in the axial direction are in contact with each other are adjacent portions (10). The rotor core (3) has a recess (11) extending in the circumferential direction at a position, facing the adjacent portions (10) of the permanent magnet (5) inthe radial direction, of the surface.
本发明提供一种能够抑制性能的下降并减小转子的涡电流损失的旋转电机和包括该旋转电机的电梯用曳引机系统。本发明的旋转电机(100)包括:具有转子铁芯(3)、多个永磁铁(5)和旋转轴(8)的转子(1);和设置在转子(1)的径向外侧的圆筒形的定子(2)。在转子铁芯(3)的表面部,在轴向上排列且彼此接触的多个永磁铁(5)的组在周向上排列配置。令在轴向上排列的多个永磁铁(5)彼此接触的部分为邻接部(10)。转子铁芯(3)在表面部的、在径向上与永磁铁(5)的邻接部(10)相对的位置具有在周向上延伸的凹部(11)。
