    • A rotation detecting device, which is compatible regardless of whether a process control device for processing an output signal of the rotation detecting device is standard one or new one having high input signal resolving power, and, also, a rotation detecting device equipped bearing assembly having such rotation detecting device, are provided. The rotation detecting device includes an encoder provided rotatably and having a plurality of circumferentially equidistantly arranged to-be-detected poles, and a sensor for detecting the to-be-detected poles. The use is made of a multiplying unit for multiplying the phase of the to-be-detected poles from an output of the sensor. The use is also made of a pulse outputting unit for receiving an output of the multiplying unit or both the output of the multiplying unit and an output of the sensor and output pulses having two multiplying powers different from each other.
    • 无论用于处理旋转检测装置的输出信号的处理控制装置是具有高输入信号分辨能力的标准的还是新的,旋转检测装置都是兼容的,以及具有旋转检测装置的轴承组件,其具有 提供这种旋转检测装置。 旋转检测装置包括可旋转地设置并且具有多个周向等距布置的待检测磁极的编码器和用于检测待检测磁极的传感器。 使用乘法单元,用于将待检测的极点的相位与传感器的输出相乘。 还使用脉冲输出单元,用于接收乘法单元的输出或乘法单元的输出和传感器的输出以及具有彼此不同的两个乘法功率的输出脉冲。
