摘要： A steering shaft is composed of an upper shaft, a lower shaft, an input shaft, and an output shaft. The upper shaft, the lower shaft, and the input shaft can rotate together, and the input shaft and the output shaft are relatively rotatably coupled to each other via a torsion bar. The rotational position of a rotor coupled to the output shaft is calculated based on the detected rotational position of the lower shaft and a steering torque detected based on the amount of relative rotational displacement of the input shaft and the output shaft. Thus, it is not necessary to include a rotor rotational position detecting unit for detecting the rotational position of the rotor within the electric motor, which reduces the size of the electric motor.
摘要翻译：转向轴由上轴，下轴，输入轴和输出轴组成。上轴，下轴和输入轴可以一起旋转，并且输入轴和输出轴经由扭杆彼此相对旋转地联接。基于检测到的下轴的旋转位置和基于输入轴和输出轴的相对旋转位移量检测到的转向转矩来计算联接到输出轴的转子的旋转位置。因此，不需要包括用于检测电动机内的转子的旋转位置的转子旋转位置检测单元，这减小了电动机的尺寸。

摘要： An electric motor provided in a vehicle steering apparatus includes a stator coaxially surrounding a steering shaft, an inner rotor disposed on the inner periphery of the stator, and an outer rotor disposed on the outer periphery of the stator. The facing area between the stator and the rotor can be increased by providing the inner rotor and the outer rotor in the electric motor. Consequently, the electric motor can be miniaturized while a certain output thereof is maintained. The vehicle steering apparatus can be miniaturized by miniaturizing the electric motor.

摘要： A vehicle steering apparatus includes a steering member; a steering shaft connected to the steering member; a torque sensor for detecting a steering torque inputted into the steering member; and an electric motor for generating power that is transmitted to the steering shaft based on the steering torque detected by the torque sensor. The electric motor includes an annular rotor and an annular stator. The annular rotor includes an annular rotor core which coaxially surrounds the steering shaft and is rotatable together with a part of the steering shaft. An annular accommodation space is formed between an outer circumference of the steering shaft and an inner circumference of the annular rotor core, and at least a part of the torque sensor is disposed within the annular accommodation space.
