Pneumatic grippers have been prevalent for the last 3 decades in Factory Automation but the advance of collaborative robots has accelerated the conversion to Electric Grippers. With an ever-changing environment, cost optimization and additional intelligence are needed to meet flexibility and interchangeability requirements. Error proofing is in demand 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. Portescap provides advanced mini motor solutions for parallel grippers, angular grippers, rotary grippers, and radial grippers.
Portescap mini motors can be found in grippers for various machinery and equipment including: assembly lines, lab automation, cobots, mobile robots, and packaging.
- High motor efficiency reduces power consumption
- Low inertia and high speed reduces cycle time
- Brushless DC slotless technology provides long lasting and reliable operation
- High power density enables wider range of gripping force
- Motor feedback can be incorporated for grip programming and feedback
- Flat disc magnet steppers to save weight and reduce size
