Description

The Mitsubishi MELSERVO-J4 Series Rotary Servo Motor offers ultra-low inertia, small capacity, to medium inertia, large capacity motor configurations suited to a range of automated applications including semiconductor manufacturing systems, X-Y tables, robotics, food processing and packaging machines, press machines and more.

Units integrate a standard-issued 22-bit absolute feedback encoder that operates at 4,194,304 pulses per revolution. Thanks to these inbuilt encoders, technicians can configure absolute position detection systems without additional components beyond a battery.

The HG-AK Series has a maximum rated speed of 6000rpm, with 10 to 30W output, a highly compact design built for ultra small capacity requirements, with an IP55 enclosure rating. This motor is designed for us in applications involving assembly, robots, and positioning systems.

The HG-UR Series is a flat type, medium capacity motor with a 2000rpm rated speed, 0.75 to 5kW out range, with an IP65 rated enclosure. This motor's flat motor structure makes it ideal for tighter installation spaces, and can be used with applications including robots, and food processing machines. This series is compatible with the HC-UP product family.

The HG-RR Series has a 3000rpm rated speed, with 1 to 5kW output range, and an IP65 enclosure. This motor is built around ultra-low inertia needs, ideal for high-throughput material handling systems.

The HG-JR Series is a medium to large capacity motor line with 1000 to 3000rpm rated speeds, and 0.5 up to 55kW output, depending on configuration. Enclosure ratings including IP67 and IP44. These motors are designed for high-throughput and high-acceleration and deceleration operations such as injection molding machines, press machines, printing machines and food packaging machines. This product line offers compatibility with the HF-JP and HA-LP family.

The HG-SR Series is a medium capacity motor with 1000 to 2000rpm rated speeds, with 0.5 to 7kW rated output ranges. Each unit has an IP67 rated enclosure, and is designed for medium inertia tasks involving material handling systems, robots, and X-Y tables. This product line is compatible with the HF-SP family.

The HG-KR Series is a small capacity motor with up to 3000rpm rated speed, and 0.05 to 0.75kW rated output. Enclosures feature an IP65 rating. This model is built for low inertia tasks across a range of general industrial applications, including belt drives, robots, mounters, sewing machines, X-Y tables, food processing, and semiconductor manufacturing. This product line is compatible with the HF-KP family.

The HG-MR Series is a small capacity motor with up 3000rpm rated speed, and 0.05 to 0.75kW rated output. Enclosures feature an IP65 rating. This model is built for ultra-low inertia tasks in high-throughput systems such as inserters and mounters. This product line is compatible with the HF-MP family.
