How do we interpret an electric motor nameplate?
Base Speed (R.P.M.) and Frequency (HERTZ)
Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").
In most of the rest of the world, the International Electrotechnical Commission (IEC) sets the standards. Or at least many countries base their standards very closely on the IEC standards (for example, Germany's VDE 0530 standard and Great Britain's BS 2613 Standard closely parallel the IEC 34-1 standard). The NEMA and IEC standards are quite similar, although they sometimes use different terminology. Thus, if one understands the IEC nameplate, it is fairly easy to understand a NEMA nameplate, and vice versa as shown in Fig 1.1A and B.
The nameplate of a motor provides important information necessary for proper application. For example, Fig. 1.1C – AC Induction Motor nameplate shows a 30 horsepower (H.P.) three-phase (3 PH) AC Induction motor.
The following paragraphs explain some of the other nameplate information for this motor.
Voltage Source (VOLTS) and Full-load Current (AMPS)
AC motors are designed to operate at standard voltages. This motor is designed to be powered by a three-phase 460 V supply. Its rated full-load current is 35.0 amps.
Base Speed (R.P.M.) and Frequency (HERTZ)
Base speed is the speed, given in RPM, at which the motor develops rated horsepower at rated voltage and frequency. Base speed is an indication of how fast the output shaft will turn the connected equipment when fully loaded. This motor has a base speed of 1765 RPM at a rated frequency of 60 Hz.
Service Factor
Service factor is a number that is multiplied by the rated horsepower of the motor to determine the horsepower at which the motor can be operated. Therefore, a motor designed to operate at or below its nameplate horsepower rating has a service factor of 1.0. A 1.15 service factor motor can be operated 15% higher than its nameplate horsepower.
