The electrical service motor surveys analysis can provide recommendations to replace less efficient motors and identify opportunities for the installation of variable speed drives at their facility, which reduces demand and energy charges on the customer’s monthly electric bills.
What kinds of tests / evaluations are included
Different levels of survey may include various electrical, mechanical, and thermal assessments. Some of the typical components:
Why do motor surveys
There are several benefits:
-
Prevent Unplanned Downtime – If motors fail unexpectedly, they can halt production. Early detection gives time to plan maintenance.
-
Safety – Faulty wiring, loose terminals or overheating may cause fire or other hazards.
-
Energy Savings – Older, inefficient motors or motors running under poor conditions can waste energy. Replacing or repairing can reduce operating costs.
-
Cost Optimization – Deciding whether to repair, rewind, or replace motors. Also optimizing spare parts inventory (don’t keep unneeded spares; ensure critical ones are available).
-
Extending Motor Life – By maintaining, balancing loads, ensuring proper cooling/ventilation, etc., motors can work longer without failure.
-
Regulatory / Efficiency Standards – For some sectors, there are minimum efficiency requirements. A survey helps ensure compliance.
