Electric Grippers are driven by brushless servo motor.January 10, 2008 -
Offered in sizes 80 and 160, EGN Series electric 2-finger parallel grippers have stroke/finger of 8 and 16 mm, respectively. Designed for high payloads, they feature gripping forces of up to 1,000 N, multi-tooth guide, wedge-hook kinematics, and integrated Bluetooth interface. Unit is controlled by MCS external controller which is used for standardized control of all servo-electric components from SCHUNK, and facilitates programming, pre-configuration, and commissioning.

Electric Gripper with Longer Stroke: The EGN 80 and 160 from SCHUNK
11-26-2007
SCHUNK has expanded its EGN series of electric 2-finger parallel grippers to include the sizes 80 and 160, which have a stroke per finger of 8 and 16 millimeters, respectively. This upward and downward expansion of the series now makes it possible to use the exact size of gripper for each task - with exactly the right specifications, but without over-investing.
The EGN grippers can be flexibly adjusted and controlled in terms of gripping power, speed and position of the gripper fingers. As with all the electric grippers, this high degree of flexibility makes it possible to quickly adapt production and assembly systems for other products and workpieces with no mechanical conversion.
The grippers of the EGN series are, so to speak, the electrically operated brothers of the premium series PGN-plus; what the two series have in common are the housing, the robust multi-tooth guide and the wedge-hook kinematics. They are designed for high payloads and have enough power reserves to move heavy components with gripping forces of up to 1000 N. The capability of pre-positioning the gripper fingers enables short closing times and high cycle rates.
The EGN grippers are driven by a brushless servo motor, the rotary movements of which are converted into a stroke movement by means of a spindle nut. A resolver which is connected directly to the motor constantly monitors the position of the servo motor for very precise positioning of the gripper fingers.
The unit is controlled by the new external controller from SCHUNK, the MCS, which is used for the standardized control of nearly all servo-electric components from SCHUNK and enables very easy programming, pre-configuration and commissioning. With the MCS controller, command libraries can be created for use with other modules, for example. The integrated Bluetooth interface also makes it possible to modify the behavior of the controlled components from a central location, which provides an unprecedented degree of flexibility in automation processes.
