Why the nameplate matters
Electric motors must match the application technically. Small differences in voltage, speed, mounting form or protection class can matter.
A readable nameplate reduces questions and makes the assessment more reliable.
Data that should be visible
Nameplates vary, but the following data is typically important.
- Manufacturer, type and serial number
- Power in kW
- Speed in RPM or min-1
- Voltage, frequency and ampere
- Mounting form, protection class and IE class
- Weight, year and duty type if available
What helps if the plate is damaged
Additional photos of the terminal box, flange, shaft, housing and old documents can help identify the motor.
Practical checklist
- Photograph the full nameplate sharply
- Photograph the motor from all sides
- Show shaft, flange and terminal box
- State condition honestly
- Add location and quantity
