A2001901 High-Performance Dual-Mode Spindle for Mitsubishi CNC Systems
BBT30 Tool System | Y/Δ Dual-Power Configuration | Mitsubishi Optimized
The A2001901 is a precision-engineered electric spindle designed for seamless integration with Mitsubishi CNC systems, offering versatile high-performance in a robust 125mm package. Its defining feature is the Y/Δ dual-winding configuration, allowing operators to select between a high-torque mode for demanding materials or a high-power, high-speed mode for efficient machining. Pre-configured for plug-and-play compatibility, it delivers reliability and flexibility for modern machining centers.
Technical Overview
Built with a focus on rigidity and thermal stability, the A2001901 is ideal for a wide range of milling applications. The star (Y) connection prioritizes torque for challenging cuts, while the delta (Δ) connection unlocks full power at higher speeds. This adaptability, combined with dedicated Mitsubishi communication interfaces, makes it a future-proof core component for job shops and production environments utilizing Mitsubishi controls.
Core Features & Advantages
- Dual-Mode Operational Flexibility:
- Star (Y) Connection: Delivers 10.9 N·m of high torque at 5.5 kW, optimized for stable machining of steels, stainless steels, and difficult-to-machine alloys.
- Delta (Δ) Connection: Provides 7.5 kW of full power up to 27,000 rpm, ideal for high-speed milling of aluminum, composites, and detailed finishing operations.
- Certified Mitsubishi Compatibility: Equipped with a Mitsubishi serial encoder (GEL 2444M) and validated for use with M800/M80/E80/C80 series CNC and MDS-E/EH/EJ/EM/EMI-SP series drives. This ensures reliable performance, simplified setup, and stable servo control.
- Exceptional Rigidity for Accuracy: High radial stiffness (300 N/µm) and axial stiffness (100 N/µm) provide a solid foundation, minimizing deflection and vibration to ensure superior part accuracy and surface finish.
- Robust & Reliable Construction: Features a heavy-duty bearing system (7008×2 / 71910×3) with grease lubrication and a BBT30 tool holder with substantial drawbar force (2000-2600 N) for secure tool clamping.
- Effective Thermal Management: Requires an external oil or water cooling system (>6 L/min) to maintain consistent precision and protect components during extended, high-power operation.
