PLA Series
Linear Servo Motor Actuator
Faster Settling, Accuracy and Highly Repeatable Positioning
PBA’s PLA series linear servo motor actuators are “plug and play” center driven linear solutions that combine ironless and iron core linear motor technology to offer a modular actuator inclusive of precision linear encoders and linear guideways.
These modules offer optimal acceleration/ velocity possibilities and rigidity that allows for faster settling, accuracy and highly repeatable positioning.
PLA actuator is configurable as open frame systems for basic applications as well as partially enclosed and fully sealed bellow covers.
Velocity to 3m/sec
•  Acceleration up to 5Gs
•  Encoder Resolution to 0.8nm (Depends on drive)
•  Effective stroke up to 2m
