永磁同步电动机的增量式光电码盘安装位置自动检测装置
摘要：
本实用新型涉及永磁同步电动机上的增量式光电码盘的安装位置的自动检测装置。该装置包括伺服驱动器(1)、永磁同步电动机(3)、二进制可逆计数器(2)、增量式光电码盘(4)，其特征在于：伺服驱动器(1)的三相绕组接永磁同步电动机(3)，永磁同步电动机(3)转动轴上安装增量式光电码盘(4)，增量式光电码盘(4)的信号输出到一个二进制可逆计数器(2)，该二进制可逆计数器(2)的清零信号输入端口接增量式光电码盘(4)的C脉冲信号输出端。在不需要使用示波器测量码盘C脉冲信号和定子空载感应电动势的条件下，本实用新型可以使伺服驱动器自动检测到永磁同步电动机上的增量式光电码盘的安装位置。
摘要（英）：

This model utility relates to an auto detector of installation position for a incremental photoelectrical encoder on a permanent magnet synchronous motor (PMSM) and comprises a servo drive (1), PMSM (3), a binary system reversible counter (2), an incremental photoelectrical encoder (4). This model utility is featured as follows: the three phase winding of the servo drive (1) is connected with PMSM (3), the rotary shaft of the PMSM (3) is provided with the incremental photoelectrical encoder (4), the signals from the incremental photoelectrical encoder (4) is transmitted to the binary system reversible counter (2) and the reset signal input port of the binary system reversible counter (2) is connected with the C pulse signal output port of the incremental photoelectrical encoder (4). If it is no need to use an oscillograph to measure incremental photoelectrical encoder pulse signal and inductive electromotive force of the idling stator, this model utility makes the servo drive automatically detect the installation position of the incremental photoelectrical encoder on the PMSM.
