Industrial Servo Motor MITSUBISHI SERVO MOTOR HC-RFS103B Industrial Servo Motor
HC-RFS103BDescription
The HC-RFS103B is a high-performance, ultra-low inertia medium power AC servo motor engineered for precision motion control in demanding industrial automation applications. Designed for rapid acceleration, high-speed positioning, and high-frequency start-stop operations, this compact rotary motor delivers exceptional responsiveness and accuracy. It features an integrated electromagnetic brake for safe power-off position holding, making it ideal for vertical axes and applications requiring load stability. Equipped with a high-resolution absolute encoder, it ensures precise position feedback and seamless synchronization with motion control systems. The motor’s robust, IP67-rated construction provides reliable operation in harsh industrial environments, while its standardized flange mounting ensures easy integration into automated machinery.
HC-RFS103B Key Features
Ultra-Low Inertia Design: Significantly reduced rotor inertia enables lightning-fast acceleration/deceleration and exceptional responsiveness for high-frequency, high-precision operations.
Integrated Electromagnetic Brake: Built-in power-off activated brake (approx. 0.5 N·m holding torque) securely locks the shaft during power loss, preventing unintended movement of vertical or inclined loads.
High Torque-to-Inertia Ratio: Provides outstanding dynamic performance with a maximum torque of 2.5x the rated torque, handling rapid load changes and peak demands.
Wide Speed Range: Rated speed of 3,000 r/min with a maximum rotational speed of 4,500 r/min, accommodating both high-speed and high-torque requirements.
Superior Environmental Resistance: IP67 fully protected construction (dust-tight and waterproof) for reliable operation in harsh, wet, or dusty industrial conditions.
Smooth Operation: Low cogging torque design ensures minimal vibration and precise movement, even at extremely low speeds.
Compact & Lightweight: Space-saving form factor with standard flange mounting for easy installation and machine integration.
Highly Durable: Industrial-grade components and robust construction ensure long service life under continuous, high-cycle operation.
Wide Compatibility: Fully compatible with standard digital servo amplifiers, supporting seamless integration into modern automation control systems.
HC-RFS103B Materials & Applications
Materials
Stator & Rotor: High-grade silicon steel laminations for optimal magnetic efficiency and low energy loss.
Winding: High-temperature resistant enameled copper wire with Class F insulation (155°C) for high thermal stability and overload capacity.
Housing & Flange: Die-cast aluminum alloy for excellent heat dissipation, structural rigidity, and lightweight durability.
Shaft: Precision-machined hardened steel for high strength, wear resistance, and accurate load transmission.
Encoder: Sealed optical encoder module with high-impact resistant plastic and glass components.
Electromagnetic Brake: Durable friction materials with steel brake components for reliable, long-life holding.
Connectors & Cable: Industrial-grade, oil-resistant insulation with shielded cabling for electrical noise immunity.
Seals: Nitrile rubber (NBR) oil seals for IP67 protection against dust, coolant, and lubricant ingress.
Typical Applications
High-Speed Pick & Place Machines: Semiconductor manufacturing, electronic assembly, and packaging equipment.
Automotive Assembly: Precision positioning for welding, fastening, and component insertion.
Electronic Manufacturing: SMT placement equipment, chip handling, and test machinery.
Food Processing: High-speed sorting, cutting, and packaging lines.
