A motor rated at 2 hp can develop what range of horsepower if it delivers its maximum torque?

A motor rated at 2 horsepower (hp) is designed to operate at that level under normal conditions. However, when a motor delivers maximum torque, it can produce a certain range above its rated horsepower without exceeding its design limits. The range is influenced by the motor's efficiency, operating conditions, and thermal characteristics.

At maximum torque, motors typically operate in a region where they can momentarily exceed their rated power, often generating a significant boost in horsepower for short durations. Many electric motors, including those rated at 2 hp, can handle such peaks quite well, usually without lasting damage. The specific increase in horsepower at maximum torque can vary based on the motor's design and application.

It is common for motors to show performance that allows them to develop horsepower above their nominal rating—thus, a 2 hp motor could be capable of producing up to 3 to 4.5 hp when it is running at its maximum torque rating. This capacity allows for more flexibility in applications requiring higher starting torque or surge capabilities, hence making the given option for the horsepower range at peak output correct.

In this context, it is noteworthy that the higher ranges listed in other options are generally unrealistic for a 2 hp motor, as they would exceed typical limits
