Designed for high-precision industrial motion control, this 1 kW medium-inertia AC servo motor, the Mitsubishi Electric HC-SFS102B, delivers reliable dynamic performance in demanding automation architectures. Equipped with an integrated electromagnetic holding brake, this unit is engineered to maintain shaft position securely during power-off states, making it ideal for vertical axes and positioning systems requiring fail-safe operation.

Key Features

Medium Inertia Design: Optimized for stable load matching and smooth rotation under varying load conditions.
Electromagnetic Brake: Built-in safety holding brake prevents axis slippage during emergency stops or power loss.
High Resolution Feedback: Integrates seamlessly with compatible servo drives for precise closed-loop positioning.
Robust Construction: Industrial-grade sealing and heavy-duty connectors ensure longevity in harsh environments.

Applications

Vertical axis control in CNC machining centers and gantry systems.
Material handling, packaging, and automated sorting conveyors.
Multi-axis robotic positioning systems requiring static holding torque.

Empirical Engineering Insights

Alternative Models & Compatibility

The HC-SFS102B is designed to pair natively with Mitsubishi MR-J2S-100A (Analog/Pulse) and MR-J2S-100B (SSCNET) servo amplifiers. If migrating to newer MR-J4 or MR-J5 platforms, note that direct physical and electrical drop-in replacement is not supported without specialized conversion cables and parameter mapping due to differences in encoder resolution protocols.

Application Pitfalls & Engineering Notes

The integrated electromagnetic brake is strictly a holding brake and must never be used for dynamic deceleration or stopping. Engaging the brake while the motor is spinning at high speeds will cause rapid friction wear, reducing holding torque and leading to premature mechanical failure of the brake assembly.

Commissioning & Wiring Tips

Ensure that the brake release circuit is powered by an independent, regulated 24 VDC power supply to prevent voltage drops from affecting brake engagement. Always install a surge-absorbing diode in parallel with the brake terminal to protect the control relay from inductive voltage spikes during switching cycles.

Installation Guidelines

CRITICAL WARNING:

Isolate all electrical power sources before initiating installation. Verify that the servo amplifier's charge LED is completely extinguished. Residual voltage in the DC bus capacitors can cause severe electrical shock and equipment damage.

1

Mount the motor securely to a rigid machine base, ensuring precise shaft alignment with the load coupling to prevent radial and axial bearing overload.

2

Connect the encoder and power cables using original Mitsubishi MS-type military-grade connectors. Ensure the ground wire is connected directly to the protective earth terminal of the servo drive.

3

Verify that the 24 VDC brake control circuit is correctly wired through the servo amplifier's sequential output interlock before applying main power.

FAQ

Can the electromagnetic brake on the HC-SFS102B be used to stop a moving load?

No. The integrated electromagnetic brake is strictly a holding brake designed to maintain position when the motor is stopped and de-energized. Using it as a dynamic brake will cause rapid wear and failure.

Which servo amplifiers are compatible with the HC-SFS102B?

This motor is natively compatible with the Mitsubishi MR-J2S series servo amplifiers, specifically the MR-J2S-100A and MR-J2S-100B models.

What is the rated speed and maximum speed of this motor?

The HC-SFS102B has a rated speed of 2000 r/min and can operate up to a maximum speed of 3000 r/min.
