180 Series
Ritscher international Limited
Overview
The 180 Series is a premium, high-torque AC servo motor system engineered specifically for the rigorous demands of CNC turret punch presses and sheet metal fabrication machinery. Operating on a robust 380V three-phase AC supply, this motor-drive combination delivers the exceptional dynamic response, positioning accuracy, and holding torque required for high-speed indexing, precise tool positioning, and synchronized material feed in automated punching operations.
Key Features & Advantages
Extreme Dynamic Response for High-Speed Indexing: Features an exceptionally high torque-to-inertia ratio, enabling rapid acceleration and deceleration of the tool turret or material feed axis. This minimizes non-productive cycle time, allowing for faster hit rates and increased throughput.
Absolute Positioning Accuracy & Rigidity: Integrated high-resolution absolute encoder (e.g., 24-bit) provides precise feedback for closed-loop control. Combined with high loop gain and torque stiffness, this ensures micron-level repeatability in tool positioning, critical for maintaining part accuracy and preventing mis-hits, especially in multi-tool, complex patterns.
High Overload Capacity & Sustained Torque: Designed to deliver 200-300% of rated torque for short durations to handle the peak inertial loads during rapid turret rotation and the shock loads at the moment of punch impact. Maintains consistent torque at low speeds for smooth material feeding and clamping.
Robust Construction for Harsh Industrial Environments: Housed in a rugged, IP67-rated enclosure to withstand metal dust, coolant mist, and occasional chip ingress common in punch press environments. Features heavy-duty, high-capacity bearings designed for longevity under high radial and axial loads.
High Efficiency & Optimized Thermal Management: Utilizes advanced low-loss magnetic materials and efficient stator design to minimize heat generation. This allows for continuous high-duty-cycle operation without thermal derating, essential for maintaining precision during long production runs.
Seamless Integration with Press Controls: Fully compatible with the matching 180 Series servo drive, supporting high-speed deterministic networks like EtherCAT, PROFINET IRT, or POWERLINK. Enables tight synchronization between the servo axes (X, Y, C-axis) and the press clutch/ram controller for complex coordinated motion.
Low Maintenance & High Reliability: The brushless, permanent magnet design ensures long service life with minimal maintenance. Built to withstand the constant vibration and mechanical shocks inherent in punch press operation.
Technical Specifications
Frame Size: 180mm square flange.
Power Supply: 3-Phase AC 380V (±15%), 50/60 Hz.
Power Range: Typically from 1.5 kW to 7.5 kW, scalable to press tonnage and axis requirements.
Rated Speed: Common speeds: 1500 RPM or 2000 RPM, with a wide constant torque range.
Feedback Device: Multi-turn absolute encoder with high-temperature rating.
Protection Class: IP67 (dust-tight and protected against temporary immersion).
Insulation Class: Class F (155°C) with embedded thermal sensors (PTC/KTY).
Brake: Optional high-torque, fail-safe holding brake for vertical axis or tool turret security.
Application-Specific Role in CNC Punch Presses
C-Axis (Turret Drive): Provides precise, high-torque rotation for indexing the heavy turret to the correct tool station.
X & Y Axes (Material Feed): Drives the ball screw or rack-and-pinion systems for accurate sheet positioning with rapid traverse speeds.
Synchronization: Ensures perfect timing between sheet movement, turret index, and punch ram stroke for optimal efficiency and accuracy.
Why Choose the 180 Series Servo Motor for Your Punch Press?
In CNC punching, speed, accuracy, and uptime directly translate to profitability. The 180 Series Servo Motor is engineered to maximize all three. Its combination of brute force for rapid indexing, pinpoint accuracy for flawless hits, and ruggedness for 24/7 operation makes it the cornerstone of a reliable, high-performance press. By minimizing cycle time and eliminating positioning errors, it reduces scrap, increases output, and delivers a rapid return on investment for press OEMs and end-users alike
