The nameplate (nameplate) is the engine passport in miniature. The ability to read the nameplate helps to correctly connect, select a replacement and maintain the machine. Let's look at the main parameters.
Main parameters of the plate
| Designation | What does it mean |
|---|---|
| kW (kW) | Rated power on the shaft |
| rpm (rpm) | Rated speed |
| V (V) | Voltage, circuits Y/Δ (e.g. 220/380) |
| A (A) | Rated current according to circuits |
| cos φ | Coefficient power |
| Hz | Network frequency (50 Hz) |
| IP | Degree of protection from dust and moisture |
| Class. insulation (F, H) | Heat resistance class |
| Efficiency / IE | Energy efficiency class |
How to use it
- Connection: Voltage and circuit (Y/Δ) determine how to connect the windings.
- Protection: nominal current is the basis for setting up a thermal relay.
- Selection of a replacement:power, speed and installation design must match.
What to do if the nameplate is erased
If the nameplate is not readable, the parameters can be determined by the standard size, number of poles and measurements - this is done when diagnostics. Knowing the power and rpm is critical when rewinding and selecting a replacement.
