The invention discloses a performance detection rack of a giant magnetoresistance GMR magnetic encoder for a permanent magnet synchronous motor. The rack comprises a fixed platform, a sensor bracket,a laser rotating speed sensor, a magnetic field intensity probe, a magnetic field intensity probe bracket, a guide waist hole, a mounting bracket for mounting and fixing the giant magnetoresistance GMR magnetic encoder, and a plurality of groups of test detection units. By means of the mode, the performance detection rack of the giant magnetoresistance GMR magnetic encoder for the permanent magnetsynchronous motor can rapidly clamp a tested sample piece, can rapidly adjust parameters such as the axial position, the magnetic field intensity, the axial angle and a load rotating speed, is simplein structure, convenient to use and high in control precision, and meets different test requirements. 本发明公开了一种永磁同步电机用巨磁电阻GMR磁编码器的性能检测台架，包括：固定平台、传感器支架、激光转速传感器、磁场强度探针、磁场强度探针支架、导向腰孔、用于安装固定巨磁电阻GMR磁编码器的安装支架以及多组试验检测单元。通过上述方式，本发明一种永磁
