HC-SFS152B | Mitsubishi | Moteur servo

Description

Designed for high-precision industrial motion control, the Mitsubishi Electric HC-SFS152B AC Servo Motor delivers robust dynamic performance within the MELSERVO system architecture. Operating at a 1.5 kW rated output and a 2000 r/min rated speed, this medium-inertia motor is engineered for applications requiring high-stability load matching and reliable speed control. Featuring an integrated electromagnetic brake for hold-on-power-off safety, the unit is constructed with a totally-enclosed, self-cooled IP65 housing (excluding the shaft throughput) to withstand challenging industrial environments where dust and liquid ingress are prevalent.

Key Features

• Integrated Electromagnetic Brake: 24V DC holding brake ensures position retention during emergency stops or power loss.
• Class F Insulation: High thermal threshold rating ensures winding protection during heavy cyclic duties.
• IP65 Protection: Dust-tight and moisture-resistant construction suitable for demanding manufacturing bays.
• Factory-Installed Oil Seal: Prevents lubricant migration when direct-coupling to gearboxes or actuators.
• Optimized Inertia Design: Medium-to-high inertia characteristics reduce resonance and ease mechanical tuning.

Industrial Applications

• Packaging Machinery: Multi-axis vertical form-fill-seal and high-speed indexing systems.
• Material Handling: Gantry crane axes, transfer shuttles, and precise positioning conveyors.
• CNC Machining: Dedicated feed axes and rotary axes on metal-cutting and woodworking stations.
• Automated Assembly: High-payload robotic pick-and-place arms and automated press feeds.

Alternative Models & Compatibility

This unit is primarily paired with the MR-J2S-100A or MR-J2S-100B series servo amplifiers. When replacing older HC-SF models, verify overall length changes due to the integrated electromagnetic brake unit ("B" designation). Motor cables and encoder lead configurations are not directly interchangeable with MR-J3 series equivalents without specific conversion connectors.

Application Pitfalls & Engineering Notes

The pre-installed oil seal should never be run dry. If the motor is mounted standalone without an adjacent fluid-filled gearbox interface, ensure a light film of synthetic grease is applied to the lip to prevent frictional overheating and premature seal deterioration. Operating temperature should be maintained below 40 degrees Celsius ambient to preserve winding lifespan under heavy duty cycles.

Commissioning & Wiring Tips

Always routing encoder cables separate from high-power phase cables is highly critical to eliminate signal interference issues. Ground the motor chassis frame firmly to the electrical enclosure backplate. When configuring the amplifier, program a brake-release delay time (typically 50–100ms) to ensure the motor is excited and torque is applied prior to releasing the physical electromagnetic brake shoe.
