Electric actuators today provide mechanical outputs sufficient to span a wide variety of applications previously considered achievable only with hydraulic power. They offer a comparable bore size to hydraulic, extending from 25mm to 127mm, with force reaching as high as 222.4kN. While achieving the same mechanical output, the more compact size also enables a smaller machine footprint. One of the clearest benefits of electric actuators is the higher level of control they provide. Coupled with a servo drive and motor, an electric actuator gives real-time motion control over position, speed, acceleration and deceleration. Whereas a hydraulic system must maintain a constant oil temperature, which can otherwise cause fluctuating viscosity that impacts performance, an electric system provides greater consistency of operation.
