The invention discloses a machine-room-less elevator traction machine which comprises a rotor and a stator. A group of torque driving components composed of the outer ring stator iron core with the outer ring stator winding and the outer ring magnetic steel assembly and another group of torque driving components composed of the inner ring stator iron core with the inner ring stator winding and theinner ring magnetic steel assembly are adopted to perform electromagnetic operation respectively, so that the electromagnetic interference is small, and the vibration noise performance is good; and the functions of large load and high power density can be realized. In addition, the inner ring magnetic steel assembly, the inner ring stator iron core with the inner ring stator winding, the outer ring stator iron core with the outer ring stator winding and the outer ring magnetic steel assembly are sequentially arranged in the radial direction from inside to outside, the axial length of the traction machine can be shortened, and the structure is more compact.

    本发明公开的一种无机房电梯曳引机包括转子和定子,其采用带外环定子绕组的外环定子铁心与外环磁钢组件组成的一组力矩驱动部件和带内环定子绕组的内环定子铁心与内环磁钢组件组成的另一组力矩驱动部件分别进行电磁运转,电磁干扰小,振动噪声性能良好,可实现大载重、高功率密度功能。另外采用内环磁钢组件、带内环定子绕组的内环定子铁心、带外环定子绕组的外环定子铁心、外环磁钢组件由内向外依次径向布置,可使得曳引机的轴向长度缩短,结构更加紧凑。
