What are the minimum facts needed to obtain a replacement motor?

• A. Voltage, RPM, wattage, phase
• B. Voltage, phase, frame number, temperature rating
• C. Voltage, RPM, frame number, type of motor
• D. Voltage, frame number, phase, insulation type

Answer: (C)

To obtain a replacement motor, knowing the voltage, RPM, frame number, and type of motor is essential. Voltage is crucial because it determines the electrical supply required for the motor to operate. RPM (revolutions per minute) indicates the motor's speed and is important for ensuring that the new motor will match the performance specifications of the equipment it will be used in. The frame number provides information about the physical dimensions and mounting configurations of the motor, ensuring that the new motor will fit correctly within the existing setup. Lastly, the type of motor—whether it is an AC motor, DC motor, or a specific type such as synchronous or induction—is necessary to ensure compatibility with the system's requirements and operational characteristics. Understanding these minimum facts ensures that the replacement motor will not only fit properly but also function effectively in the intended application, maintaining the system’s efficiency and performance.
