Electric Grippers Transition Relies on Micro Motors

Motors for Electrical Grippers

Challenge

Pneumatic grippers have been prevalent for the last 3 decades in factory automation and are well suited for automated, low-mix, high-volume applications. With an ever-changing environment, cost optimization and additional intelligence, to meet with flexibility and high mix applications, are needed. In confined spaces, the gripper and wires might also interfere with their surroundings. Error proofing is required now to detect incorrect or missed gripping, in addition to collision risks and unpredictable position moves. Operating costs are closely monitored, so wasted energy and maintenance costs are tracked to improve the overall system efficiency.

The move towards Electric Grippers allows for better control of the gripper finger position, grip detection, and control of the grip force and speed. Electric grippers also eliminate the need for air lines, thus saving power and maintenance while producing a cleaner work environment.
