    • A torque sensor, which is for an electric power steering system that has an output shaft for rotating in response to rotation of an input shaft, may include a first rotor for rotating with the input shaft, a second rotor for rotating with the output shaft, a first pinion gear mounted for rotating in response to rotation of the first rotor, a first magnet mounted for rotating with the first pinion gear, a second pinion gear mounted for rotating in response to rotation of the second rotor, a second magnet mounted for rotating with the second pinion gear, a first sensor positioned for sensing an angular position of the first magnet, and a second sensor positioned for sensing an angular position of the second magnet. The first rotor and the second rotor are mounted so that there can be relative rotation between the first rotor and the second rotor.
    • 用于具有响应于输入轴的旋转而旋转的输出轴的电动助力转向系统的转矩传感器可以包括:用于与输入轴一起旋转的第一转子,用于与输出轴一起旋转的第二转子, 安装成响应于第一转子的旋转而旋转的第一小齿轮,安装成与第一小齿轮一起旋转的第一磁体,安装成响应于第二转子的旋转而旋转的第二小齿轮,安装成旋转的第二磁体 与第二小齿轮啮合,第一传感器定位成用于感测第一磁体的角位置,第二传感器定位成用于感测第二磁体的角位置。 第一转子和第二转子被安装成使得可以在第一转子和第二转子之间存在相对旋转。
