How can you determine the rated power of an electric motor?

To determine the rated power of an electric motor, looking on its nameplate is the most direct and reliable method. The nameplate is typically affixed to the motor's housing and includes critical information such as the rated voltage, current, frequency, speed, and importantly, the rated power (measured in horsepower or kilowatts). This information is standardized and provides a quick reference without the need to interpret other documents or guides.

While checking the manufacturer's brochure, installation manual, or contacting customer service can provide useful information, these methods may not always give the most accurate or specific detail about the individual motor in question. Manufacturer brochures and installation manuals refer to general specifications and may not reflect the specific unit's rated power if there are variations in motor models. Consulting customer service can also be time-consuming and may not guarantee accurate information without details about the specific model. Thus, the nameplate stands out as the most effective source of information regarding the motor's rated power.
