有些服务中心不校准内径千分尺，因为他们把内径千分尺放在镗孔里，然后设置好, 然后把它滑出来，用校准过的外部千分尺测量内部千分尺. Is this an acceptable practice? If so, do the inside micrometers need to be calibrated?
Using the inside micrometers as gauges, 用外部千分尺进行实际测量是可以接受的. The inside micrometers should be identified as “for reference only”; and the outside micrometers must be calibrated.
范围说明该程序适用于三相鼠笼式电动机[仅限]. 进一步 the scope does not restrict it to any voltage rating. 也就是说，低压和中压三相鼠笼电动机额定值都包括在内.
A motor is received for for cleaning and changing bearings. Winding tests indicate the winding is satisfactory. 但是，它之前已经重新卷绕，可以修复认证?
作出这一决定的主要判断标准是试验的结果, and observation of the winding. The key test is the no load test, 以空载电流作为可接受性的主要指标. 如果空载电流在合理范围内，则判定绕组数据可接受(见检查表项目#18空载试验).)也, by observation if the slot fill is normal, 这是, 不低, the wire area per amp should be acceptable. If both the test and observation criteria are met, the winding can be judged acceptable for an accredited repair.
Is a spectrum analyzer required for vibration testing?
根据主要参考源AR100，只需要未经过滤的振动水平. Thus, a vibration spectrum is not required.
当AR100发生变化时，认证服务中心需要多长时间才能符合要求?
There will be a 1-year grace period following the publishing date of a revised edition of AR100; which would be sufficient time for both auditors and accredited service centers to implement any changes necessary to conform to the revised edition. 进一步, 如果AR100中出现了需要较长时间实施的变更, that would be dealt with on a case by case basis.
How many thermocouples does our burn off oven need?
每个部件(通常是定子)上都需要一个温度传感器，在烧断炉中进行处理.
Is part temperature sensing required for the bake oven?
No, oven temperature sensing is required. 然而, 必须确保烘烤的部件达到清漆/树脂制造商的最低固化温度, 并保持在该温度或以上，至少达到清漆/树脂制造商规定的最短固化时间.
是否有特定的信息需要被记录?
要求“保持认证标签序列号和它们所放置的电机的记录”.“是否有特定的信息需要被记录? Is there a reporting requirement for the information?
“获得认证的公司必须保留一份带有相应标签的电机清单和服务中心的工作编号. 至少，每个认可的维修清单必须包括标签编号和服务中心的工作编号. Additional information about the repaired motor, 比如制造商, 额定功率, 速度, 序列号, 等. can be included in the listing, but is not required."
网赌平台有客户经常把不带接线盒的电机送去维修. Is this motor eligible for an Accredited repair?
没有接线盒的电机有资格进行认证维修.
带正弦波滤波器的变频器可以用作电机测试面板上的电源吗?
网赌平台的服务中心使用带正弦波滤波器的变频器作为电机测试面板的电源. It also has readouts for phase voltage and current. 这是否满足EASA认证对测试面板的要求?
Based on the 认证 Checklist and AR100 clause 4.5、电机需要在额定电压和频率下试验运行. 因此，只要测试运行符合这些要求，使用变频器是可以接受的. 使用正弦波滤波器是有益的，因为测试结果应该与电机从公用事业电源运行时的结果相比较. 电机的电压和电流应该在测试面板和电机输出之间的某处测量.
