Mitsubishi HF-SP81K AC Servo Motor for MELSERVO-J3 Series

The Mitsubishi HF-SP81K (HF-SP81K) is a high-performance AC brushless rotary servo motor engineered for industrial automation tasks within the Mitsubishi Electric MELSERVO-J3 drive series. Delivering precise velocity and positioning performance, this servo motor operates on a 200 V AC supply class and delivers a rated output of 850 W (0.85 kW) alongside a continuous rated torque of 8.12 Nm at a rated rotational speed of 1,000 RPM. Designed to operate reliably under continuous duty, the motor draws a rated current of 4.5 A. Equipped with an integrated 18-bit absolute feedback encoder, the HF-SP81K provides high-resolution position tracking to ensure smooth dynamic motion control across automated machinery. Mechanical specifications include a keyed output shaft for secure power transmission and a standard 130 x 130 mm mounting flange. Built with robust environmental sealing rated at IP67, the unit offers high resistance to dust ingress and moisture in demanding industrial environments, functioning within an ambient operating temperature range of 0 to +40 degrees Celsius. It serves as an essential motion component in automated assembly, material handling, packaging, and CNC systems.
