Mitsubishi HF-SP81MK-S12 AC Brushless Servo Motor for MELSERVO-J3

The Mitsubishi HF-SP81MK-S12 (HF-SP81MK-S12) is an AC brushless rotary servo motor designed for use with Mitsubishi MELSERVO-J3 series drive systems. Operating on a 200 V AC supply voltage class, this motor provides a rated output power of 850 W (0.85 kW) with a rated operating current of 4.5 A. It delivers a rated torque of 8.12 Nm at a rated rotational speed of 1000 RPM, providing stable torque output and smooth dynamic response for industrial automation machinery. Equipped with a straight shaft and an oil seal, the unit incorporates an integrated 18-bit absolute feedback encoder to maintain precise position and speed tracking. The motor features standard 130x130 mm flange mounting dimensions and provides an IP67 degree of protection against dust and liquid ingress, making it suitable for demanding factory environments. It is rated for operation across an ambient temperature range of 0 to +40 degrees Celsius. This servo motor is commonly deployed in precision motion control applications, packaging machinery, handling systems, and automated production lines requiring reliable continuous performance.
