Principle of operation

1 POWR MSTR Power Meister A servo motor controls hydraulic pump speed and direction. enerate pressure and flow to match the operating cycle of machinery and to stop during idle times. ncredible energy savings by only operating when necessary. Also, position, speed, and pressure are controlled with great precision by using a high-speed digital processing servo controller. eatures igh power with MPa maximum pressure. esigned so pump operates only when necessary for energy savings and low noise. reat energy savings compared to conventional hydraulic systems. igh-speed processing of the servo controller makes positioning on the order of μm possible. ompact all-in-one design saves space. (select either vertical or horizontal setup) low of hydraulic fluid ifting Table ylinder Tank Principle of operation Rotating the motor forward brings hydraulic fluid to the head side of the cylinder which lifts the cylinder. Reversing the motor pushes hydraulic fluid to the rod side and pushes the cylinder down. The direction the pump rotates controls the direction of the cylinder, and the speed of rotation controls the speed. Maintain pressure Switch by control valve is not required owering System onfiguration (Standard onfiguration) Signals to operate the cylinder (position, speed, and pressure) are sent from the control equipment to the servo controller and the hydraulic unit responds according to the signals. The servo controller receives feedback from sensors and accurately controls the cylinder so the deviation from the signals is 0. A feedback system using position and pressure sensors makes it possible to accurately control position, speed, and thrust (pressure).

When you select a product, you first need to clarify the operating cycle and load of your machinery (the hydraulic cylinders that the Power Meister will drive) in advance and then consult with us. (Note 1) There is a limit to the operating pressure at maximum RPMs due to the low torque that is characteristic of this motor's output at high RPMs. (Note 2) Theoretical flow under no load. Actual flow varies according to load pressure. (Note 3) Rated pressure is rated torque of the motor, maximum operating pressure is pressure output at 150% torque. owever, if this pressure exceeds MPa, the maximum operating pressure of the hydraulic unit is below MPa. Also, the maximum RPM and operating pressure may be limited depending on the acceleration, deceleration, and load conditions. larify your machinery's operating conditions first, and contact us for more information. (Note 4) f the fluctuation in oil volume is greater than the allowed values an auxiliary tank can be connected to resolve this. ontact us for more information. (Note 5) f your selection does not include a tank, then a separate oil tank is required. We can also manufacture oil tanks, so contact us for more information if you are interested. (Note 6) The temperature of the hydraulic fluid is affected by many factors, such as the hydraulic unit's operating environment, operating methods, and load conditions. The customer must confirm the unit's actual continuous operating conditions. Also, long-term, continuous operation under pressure or high-frequency reciprocal operation may result in increased oil temperatures. Therefore, operating pressure limits or installation of a cooling system may be necessary. ontact us for more information. -36
