What is meant by the term "reversible motor"?

• A. A motor that operates on both AC and DC
• B. A motor designed to rotate in both directions
• C. A motor that is reversible in polarity
• D. A motor that can change voltages

Answer: (B)

The term "reversible motor" refers specifically to a motor that is designed to rotate in both directions. This capability is essential in applications where the direction of movement may need to be changed frequently, such as in conveyor systems, power tools, or robotics. In such motors, the design includes mechanisms that allow for the reversal of the phase sequence in AC motors or the switching of connections in DC motors, which facilitates the change in rotation direction. This distinct feature is what fundamentally defines a reversible motor, making it highly versatile for various engineering and industrial applications. The other options do not accurately describe the characteristics of a reversible motor. For example, a motor that operates on both AC and DC does not necessarily imply that it can reverse direction, and a motor that is reversible in polarity refers to a specific electrical characteristic rather than its operational direction. Additionally, the ability to change voltages is related to the motor's power management rather than its capability to reverse rotation.
