Compared with other systems adopting hydraulic pressure or air pressure as a driving source, the electric cylinder is directly controlled by the motor, and intermediate media such as oil, gas and the like are not needed to transmit power, so that inaccuracy and inconvenient use caused by errors of a system generated by oil leakage and gas leakage can be avoided, and the electric control system has more excellent control performance, higher speed, higher bearing capacity and longer service life compared with a hydraulic system. The control performance of the system is not affected by the factors such as ambient temperature, easily polluted hydraulic valves, fluid media and the like. The wiring between the motor and the servo drive is also very simple and no complex oil pumps, pipes, cooling systems and other auxiliary facilities in the hydraulic system are required. Compared to cylinders, electric cylinders can be used in applications where high pressure air is less suitable.
