LPA Low Profile Rotary Actuator with Integrated Servo Drive
The Integrated Series is a family of compact actuators that deliver high torque with exceptional accuracy and repeatability. These servo actuators feature high precision Harmonic Drive® gearing combined with a brushless servo motor, magnetic dual absolute encoders and an Integrated Servo Drive with CANopen® or EtherCAT® communication options. This revolutionary product eliminates the need for an external drive and greatly simplifies cabling yet delivers high-positional accuracy and
torsional stiffness in a compact housing.
