Exlar Corporation has expanded its Tritex II integrated rotary actuator family with a new 75-mm frame size. The AC-powered 75-mm rotary actuator has an integrated 1.5-kW servo amplifier and offers torques to 60 lbf-in peak and 30 lbf-in continuous. DC-powered Tritex II actuators with an integrated 750-W servo amplifier are also available. Exlar’s Tritex II Series Integrated Actuators are offered with either an AC- or DC-powered servo drive, digital position controller and rotary actuator. All elements are assembled into a single, compact waterproof housing. Tritex actuators have built-in mechanical converters, eliminating the need for traditional ball screw or gear reducer mechanisms, the company says. Incorporating the required position control and power electronics into the actuator also eliminates the external servo amplifier and the cables associated with a typical servo system.
