What type of device converts the angular position of its rotor to an electrical output?

The correct answer for the type of device that converts the angular position of its rotor to an electrical output is a rotary encoder. A rotary encoder is specifically designed to provide feedback regarding the rotational position of an object. It does this by converting the mechanical motion (the rotation) into a corresponding electrical signal, which can then be interpreted and processed by control systems or other electronic devices.

Rotary encoders can be categorized into two main types: incremental and absolute. Incremental encoders provide information about movement and direction, while absolute encoders give a unique value for each position of the rotor, providing precise position data at all times. This capability makes rotary encoders useful in various applications, including robotics, automation, and motion control systems.

In contrast, torque converters and torque transmitters are devices involved in the transfer of power and torque in mechanical systems, not in converting angular position into electrical signals. On the other hand, voltage regulators serve a different purpose by maintaining a constant voltage level in various electrical applications, unrelated to the measurement of angular position. Hence, the rotary encoder’s specific function aligns perfectly with the question’s requirements about converting angular position to an electrical output.
