The electro-hydraulic servo hydraulic press is an innovation and revolution in the hydraulic industry. It uses a servo motor to replace the original ordinary three-phase asynchronous motor. The start and stop of the motor, the pressure of the hydraulic oil, and the speed of the oil cylinder are all completed by the torque speed of the servo motor. The system uses the pressure sensor to sample the pressure of the system. The servo control performs closed-loop control on the hydraulic oil pressure by reading the pressure value. advantage A. The noise of servo motor is low, and the noise of universal motor is very high; B. The servo motor saves energy and electricity. The motor will only start when the hydraulic press operates in a process. When the hydraulic press stops or does not perform a process, the motor will stop. The servo motor has different pressure on various processes and different motor speed (adjustable and settable). A
