An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
Robot Actuators-Different Types. An actuator is a mechanism for activating process control equipment by the use of pneumatic, hydraulic, or electronic signals.There are several types of actuators in robotic arms.Synchronous Actuator-The motor contains a rotor that rotates in synchrony with the oscillating field or current.1  Brushless DC Servo-This synchronous electric motor features permanent magnet poles on the rotor, which are attracted to the rotating poles of the opposite magnetic polarity in the stator creating torque.ynchronous Actuator-The motor contains a rotor that rotates in synchrony with the oscillating field or current. 1  Brushless DC Servo-This synchronous electric motor features permanent magnet poles on the rotor, which are attracted to the rotating poles of the opposite magnetic polarity in the stator creating torque.
