Mitsubishi HC-SFS702 AC Servo Motor — New In Box, Factory Sealed

Condition: Brand New · Original Packaging · Factory Sealed

Part Number: HC-SFS702 / HCSFS702

Series: HC-SFS 

Compatible Amplifiers: MR-J2S / MR-J3 / MR-J4

Product Overview

The Mitsubishi HC-SFS702 is a 7.0 kW AC servo motor built for high-demand industrial motion control. With a continuous rated torque of 33.4 N·m, a top speed of 2,000 rpm, and a 17-bit absolute encoder delivering 131,072 pulses per revolution, it's the kind of unit that gets specified when positioning accuracy and long-term reliability aren't negotiable.

Every unit we ship is brand new and factory sealed — untouched, uninstalled, and in its original Mitsubishi carton. No refurbishment, no repackaging, no field history.

Key Specifications

Why Engineers Choose the HC-SFS702

Precision that holds up over time. The 17-bit absolute encoder retains position data across power cycles, eliminating the need for a homing routine after every restart. In high-cycle production environments, that adds up.

Built for real-world conditions. IP65 shaft sealing handles dusty press rooms, wash-down zones, and food-adjacent production lines without requiring additional motor protection.

Wide amplifier compatibility. Works across MR-J2S, MR-J3, and MR-J4 series amplifiers — useful when upgrading a system without replacing every component in the cabinet.

Thermal headroom where it matters. Class F insulation manages heat in continuous-duty cycles, reducing the risk of winding degradation in applications that run long shifts with limited cooling.

Typical Applications

CNC Machine Tools — Axis drives where encoder precision directly affects surface finish and dimensional accuracy on finished parts.

Industrial Robots — Joint actuators in 6-axis arms and SCARA systems that require fast response, high repeatability, and long service intervals.

Press & Stamping Lines — Feed axes that must absorb repetitive shock loads and return to position accurately after each stroke.

Packaging Machinery — Cut-to-length, film wrapping, and case-erecting equipment where throughput is tied directly to velocity control consistency.

Whether you're building out a new machine, stocking a spare for an installed fleet, or sourcing an emergency replacement to minimize downtime — a sealed, verified-new HC-SFS702 ships ready to install.

Frequently Asked Questions

Q: Which servo amplifiers are compatible with the HC-SFS702?

A: The HC-SFS702 works with Mitsubishi MR-J2S, MR-J3, and MR-J4 series servo amplifiers at the appropriate power rating. Always confirm the amplifier's rated output aligns with the motor's 7 kW / 200V spec before commissioning.

Q: Does the motor ship with an encoder cable or power connector?

 A: No. The HC-SFS702 ships as the motor unit only, consistent with standard Mitsubishi factory supply. Encoder cables, connectors, and mounting hardware are available separately through Mitsubishi's accessory catalog.

Q: What does "New In Box, Factory Sealed" mean exactly?

A: The motor has never been powered on or installed. It remains in its original Mitsubishi packaging with all factory seals intact — the same state it left the production facility. No reconditioning or relabeling has occurred.

Q: Can the HC-SFS702 be mounted vertically?

A: Yes. The HC-SFS series supports both horizontal and vertical orientations. For vertical axis applications, ensure the system includes a mechanical brake or that the amplifier's dynamic brake is configured to hold load position during power-off.

Q: What type of encoder does this motor use?

A: A 17-bit absolute encoder (131,072 pulses per revolution). Position data is retained without battery backup in multi-turn absolute configurations, making it well-suited for applications where re-homing after a power loss is not practical.
