Electric rotary actuators are used to drive components rotationally through electromagnetic power from an electric motor. They normally provide indexing & control capabilities to permit many positions stops with strokes. The rotating element of this actuator is either a circular shaft otherwise a table. Circular shafts frequently comprise keyways whereas tables offer a bolt model for mounting additional components. The specifications of this actuator include voltage supply, maximum torque, repeatability, load capacity, operating temperature, rotation angle, and linear stroke. Electric rotary actuators are used in different applications like high-power switching gears, the electric power industry, the automotive industry & packaging applications.
