Decoding Nameplate of Motors

 When reading the nameplate of a motor, you'll typically find the following key information:

1. Manufacturer: The brand or company that made the motor.

2. Model Number: Unique identifier for that specific motor type.

3. Serial Number: A unique number assigned to that individual motor, often for warranty or service purposes.

4. Voltage: The operating voltage required, usually given in volts (e.g., 230V, 460V).

5. Current: The amount of current the motor draws, measured in amperes (A).

6. Frequency: The frequency of the electrical supply (e.g., 50Hz, 60Hz).

7. Power: The motor's output power, commonly in horsepower (HP) or kilowatts (kW).

8. Speed: The motor's speed in revolutions per minute (RPM).

9. Service Factor: The motor's overload capacity, usually a value like 1.15, which means the motor can handle 15% more than its rated load.

10. Efficiency: How efficiently the motor converts electrical energy into mechanical energy (often given as a percentage).

11. Frame Size: The physical dimensions of the motor, used to determine compatibility with mounting and other equipment.

12. Insulation Class: The type of insulation used, which determines the temperature rating (e.g., Class F).

13. Duty Cycle: How long the motor can run before it needs to cool down (e.g., Continuous, Intermittent).
