定子倒带:当事情变得紧张
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.

Common Motor Issues in the Service Center
Three of the most common three-phase motor problems we receive inquiries about are:
- “The motor is drawing high no-load current.”
- “The current of the three line leads is not balanced.”
- “马达发热了.”
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! (聚氯化联苯)
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.
