Industrial Servo Motor MITSUBISHI SERVO MOTOR HC-RFS103B Industrial Servo Motor
HC-RFS103B Description
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-Resolution Absolute Encoder: 17-bit absolute encoder (131,072 pulses/rev) delivers industry-leading positional accuracy and low-speed stability, eliminating homing routines.
- 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.
