在中国先进研究堆（ CARR）调试阶段，发现其控制棒驱动机构在转向过程中存在驱动线圈与控制棒运动不同步的现象。为掌握控制棒驱动机构的转向性能参数，在静水条件下进行了控制棒驱动机构转向性能测试试验。试验表明：驱动线圈与控制棒运动不同步是磁悬浮式控制棒驱动机构的固有特性；棒位、棒速和驱动线圈通电电流大小等因素对静水条件下转向性能影响不大，且四组驱动机构静水条件下转向性能具有一致性。

During the commissioning phase of China Advanced Research Reactor ( CARR) , operator found the a-synchronism between drive coils and control rod when the control rod drive mechanism ( CRDM ) taking inver-sion.With the aim of acquiring inversion performance of the CRDM , a CRDM inversion performance test has been taken under the condition of static coolant .The result of test shows that asynchronism between drive coils and control rod is the intrinsic characteristic of magnetic suspension CRDM ,the factors , such as control rod po-sition, control rod speed and drive coil current , have limited influence on static coolant inversion performance , and the inversion performance of four groups CRDM have uniformity under static coolant condition .
