What does a motor's "nameplate" indicate?

The motor's "nameplate" serves as a critical source of information regarding important specifications of the motor. It typically includes details such as the voltage rating, horsepower (HP), amp draw, RPM (revolutions per minute), frequency, phase information, and sometimes efficiency ratings. This data is essential for ensuring that the motor is matched to the correct power supply and application requirements, which is vital for optimal performance.

While safety standards and certifications, warranty information, and installation guidelines are important aspects of motor safety and functionality, they are not primarily found on the nameplate itself. Instead, the nameplate is specifically designed to provide technical specifications that are immediately necessary for understanding how the motor should be used and maintained. This technical information allows technicians and engineers to make informed decisions during installation, troubleshooting, and maintenance.
