Examining the Causes of High Motor Current
Are you encountering high no-load current or high current with load? This presentation will look into the causes and cures.
Choosing the Right Insulation System for Medium Voltage Rewinds
的 insulation system chosen for 任何 rewind should be suitable for the application, 电压等级, and the winding process capability of the service center. In most cases, adherence to “equal to or better than” selection is a good practice.
Roving Chief Executive Program Promotes Peer Relationship Building
的re are few places where you can share the ups and downs of your business with friends who instantly identify with your issues. 的 Roving Chief Executive (RCE) Program can provide that to you.
Stator Rewinds: When Things Get Tight
When preparing to rewind random or form-wound status, sometimes there just doesn’t seem to be enough room in the stator slot for the desired conductor area and insulation quantities. This presentation looks at balancing stator copper losses against insulation reliability.
Converting 振动 Units: Process and Solutions
As we communicate internationally, language barriers persist. In the technical fields, the metric-imperial units clash is slowly diminishing. M任何 vibration analysts are “bilingual” in that respect and are comfortable using either system. But for more casual users who may only encounter vibration data in regard to meeting specs, unfamiliar vibration amplitude units can be a challenge.
管理 Pulse Survey: Don’t Disregard Outside Assessments When Selecting New Team Members

的 Value of Industry Representation
Why It Matters to EASA and (Importantly!)你
As a benefit of membership in EASA, we get (literally) an army of people every day to represent our interests in industry and government regulations. And they often provide us with valuable insight and positive change to “the way we’ve always done it.”
Axial Thrust in Rotodynamic (Centrifugal) 泵
When repairing centrifugal and axial flow pumps, axial thrust is a concern. An understanding of the causes and the mitigating provisions of various pump designs will help repair technicians to ensure those provisions work properly.
Common Motor Issues in the Service Center
Three of the most common three-phase motor problems we receive inquiries about are:
- “的 motor is drawing high no-load current.”
- “的 current of the three line leads is not balanced.”
- “的 motor is running hot.”
Even if you have never faced one of these issues, read on because it is almost inevitable that you will, and you will want to know what to do about it.
小心多氯联苯! (Poly-Chlorinated BiPhenyls)
PCBs have been identified as a likely carcinogen for humans. If your service center is asked to pick up equipment that you suspect MAY contain PCBs, have it field 测试ed BEFORE picking it up. Once you pick up a device that contains PCBs, the responsibility is yours.
