The Mitsubishi HC153S-SZ is a 1.5kW high-torque AC servo motor designed for precision industrial motion control. Operating at up to 3000rpm (rated) with a robust IP65 enclosure, it integrates an absolute encoder (OSA104S2) for accurate position feedback—ideal for automated machinery, robotics, and CNC systems. Compatible with Mitsubishi’s MDS-A/B or MR-J2 series drivers, it balances reliability, compact design, and consistent performance for demanding industrial applications.
