Description

Engineered for high-capacity industrial motion control, the Mitsubishi Electric HC-SFS102BG1H 1/29 servo motor provides exceptional positioning accuracy and torque multiplier capabilities under heavy physical loads. This industrial drive features a 1.0 kW rated output paired with a specialized G1H leg-mounted reduction gearbox, delivering a 1/29 reduction ratio optimized for high-inertia conveyor, positioning, and mechanical system drives. Equipped with an integrated electromagnetic holding brake, this unit ensures reliable position retention and fail-safe safety compliance in vertical axes and cyclic stop-start automated setups.

Key Features

• High-Torque Output: Optimized 1.0 kW power delivery combined with a 1/29 gear reduction ratio for massive low-speed driving torque.
• Integrated Holding Brake: Built-in electromagnetic brake prevents load slippage during power loss or system disable cycles.
• Rugged Leg-Mounted Gearbox: The G1H foot-mount configuration provides structural stability, distributing mechanical stress directly to the mounting frame.
• Reliable Speed Profile: Operates at a rated base speed of 2000 r/min before gear reduction, ensuring consistent dynamics.
• Low Maintenance Design: Heavy-duty industrial seals and lubricated gears minimize wear under continuous operation profiles.

Heavy Industrial Applications

• Automated material handling and heavy assembly conveyor systems.
• Vertical lift mechanisms and overhead hoist axes requiring reliable physical holding brakes.
• Rotary index tables and heavy-duty packaging machinery.
• Precision positioning systems in harsh manufacturing environments.

Empirical Engineering Insights

Alternative Models & Compatibility

This servo motor is typically driven by Mitsubishi MR-J2S-100A or MR-J2S-100B series amplifiers. Ensure your amplifier configuration parameters (specifically the motor selection code) match the 1.0 kW HC-SFS series specification. Retrofitting this motor into standard non-geared systems requires adjustments to the mechanical leg-mount footings and parameter reconfiguration for electronic gear ratios to match the 1/29 reduction.

Application Pitfalls & Engineering Notes

Because this assembly includes a 1/29 reduction gear, the output shaft experiences high torque amplification. To prevent mechanical failure, verify that all coupling elements and driven shafts are rated for the high torque profile of this motor configuration. Always monitor heat accumulation in the gearbox under high-duty cycle profiles; ensure the foot-mounting plate acts as an effective heat sink and has clear ventilation access.

Commissioning & Wiring Tips

Always route the motor's power lines and internal brake control wires through isolated conduits, separate from the high-resolution feedback encoder cables, to suppress electrical noise. Ensure your external 24VDC brake supply is robust and properly interlocked with the servo drive's "Ready" output to prevent the drive from attempting to rotate the shaft while the mechanical brake is still engaged.

Installation Guidelines

1. 1 Anchor the G1H gearbox foot mounts securely to a rigid, precision-ground machine baseplate to prevent vibration and misalignment.
2. 2 Confirm that the motor shaft axis is aligned with the driven load to prevent excessive radial and axial loads on the output bearings.
3. 3 Connect the heavy-duty power and encoder MS-style connectors, verifying the lock mechanisms are sealed to protect against dust and liquid ingress.
4. 4 Perform a low-speed manual test spin using drive manual jogging controls to confirm correct rotation direction and verify brake release functionality.
