Which item is not typically found on a motor nameplate?

• A. Battery type
• B. Frame size
• C. FLA
• D. Locked rotor letters

Answer: (A)

Motors have nameplates that list the electrical and mechanical ratings you need for proper installation and operation. These plates show the frame size, which indicates the motor’s physical mounting and shaft size, the full-load amps (FLA) needed to size wiring and protective devices, and data related to starting and running, such as locked-rotor current or torque and operating voltage, frequency, and speed. The information helps you choose compatible drives, cables, and circuit protections and ensures safe, reliable operation.

Battery type isn’t part of a motor’s own rating because the nameplate describes how the motor itself performs, not the chemistry of the power source feeding it. A separate power-system specification would cover battery characteristics, while the motor nameplate focuses on voltage, current, speed, efficiency, and starting-related data. That’s why battery type is not typically found on a motor nameplate.
