HG-KR73 MITSUBISHI Servomotor HG Series, Power 750 W

MITSUBISHI  HG-KR73 Servomotor HG Series, Power 750 W

Servomotor HG Series, Power 750 W; Torque 2.4 Nm, Max. Torque 8.4Nm

The HG-KR73 belongs to Mitsubishi's MR-J4 series servo motors, optimized for dynamic performance in machinery requiring rapid acceleration/deceleration and precise positioning. Its compact design (total length of 130mm) and lightweight construction (2.8kg standard, 3.8kg with brake) make it suitable for space-constrained applications. The motor features a 22-bit absolute/incremental encoder (4,194,304 pulses/rev) for sub-micron positioning accuracy and includes built-in vibration suppression to enhance low-speed stability.
