The Mitsubishi Electric HG-KR73B is a low-inertia, small-capacity AC servo motor of the HG-KR series. This version has a built-in spring-actuated safety brake on 24 V DC that draws 10 W and holds with a static friction torque of 2.4 N·m or more. It delivers 0.75 kW rated output, 2.4 N·m rated torque and 8.4 N·m maximum torque at 3000 r/min rated and 6000 r/min maximum speed, with 4.8 A rated and 17 A maximum current. Feedback comes from a 22-bit encoder shared by absolute and incremental systems with 4194304 pulses/rev, and the totally-enclosed, natural-cooling frame is rated IP65 with insulation class 130 (B) for 0 °C to 40 °C ambient operation. With the brake fitted, moment of inertia is 1.37 x 10-4 kg·m2 and mass is 3.8 kg.
