Mitsubishi FFR-MSH-170-30A-SF1 Brushless AC Servo Motor for MELSERVO J2S Series

The Mitsubishi FFR-MSH-170-30A-SF1 (FFR-MSH-170-30A-SF1) is a brushless AC rotary servo motor developed for use with Mitsubishi Electric MELSERVO J2S series servo systems. Designed for demanding motion control machinery, this discontinued motor features a straight shaft configuration, an integrated electromagnetic brake, an oil seal, and a built-in 17-bit absolute feedback encoder that delivers high-resolution positioning equivalent to 131,072 pulses per revolution. Operating on a 200 VAC supply voltage class, the motor delivers a rated power output of 11 kW, a rated torque of 70 Nm, and a rated rotational speed of 1,500 rpm with a rated current draw of 65 A. It is constructed for robust operation with an IP44 protection degree and is rated for ambient operating temperatures ranging from 0 to +40 degrees Celsius. Mechanical integration is supported via a standard 250 by 250 mm flange mounting arrangement. This servo motor is typically utilized in precision positioning, automated assembly, material handling, packaging lines, and machine tool axes requiring holding torque and dynamic motion control.
