Function principle
The Electro-Servo-Cylinder developed by EMG is used as a control and positioning cylinder. It converts by means of a Planetary Gear Thread (PGT) the rotation generated by a threephase current motor into a linear movement.
The function principle is based on a rolling motion at low friction and consequently mimimum wear.
The standard model of the Electro-Servo-Cylinder consists of the following components:
- Three-phase asynchronous motor
- Spindle with planetary gear thread, thrust housing and piston rod with knuckle
- Rotating lock of piston rod
- Housing with pivot
Customer benefits
- Compact design without gear
- High drive speed, small motor torque
- High positioning accuracy
- Clean and environmentally friendly
- Compact design at high power transmission
- Integration of position transducer and limit switch
- High reliability, long life cycle
EMG ESZ – our own cylinder with planetary screw drive. Made in Germany. Low wear even with high forces. Even with regular, small corrective movements, such as those that occur in web guiding and cause problems for other cylinders, the EMG ESZ works reliably for years.
