Which type of motor can only turn part of a rotation?

The limited rotation motor is designed specifically for applications where only a portion of a full rotation is required. This type of motor is commonly used in scenarios where precise positioning within a specific angle is necessary, such as in robotics, automation, or control systems.

Limited rotation motors are ideal for tasks that involve a defined range of motion and are often designed to operate within this specific range without exceeding it. This makes them particularly useful for applications that require accuracy and repeatability within a set angular displacement, such as valves or clamps that need to be opened or closed to a precise angle.

In contrast, full rotation motors enable complete, unrestricted rotational movement, while continuous rotation motors offer endless rotation capabilities. Step motors, on the other hand, achieve precise control over movement by dividing a full rotation into discrete steps, but they may not necessarily be limited to only partial rotations in their design. Thus, a limited rotation motor is uniquely suited for scenarios requiring control over specific angular movements, confirming its role in precise applications.
