The DSC1 Series (DSC 045) three-phase permanent-magnet AC synchronous servo motors, engineered and manufactured by Baumüller (Nuremberg, Germany), represent state-of-the-art industrial drive technology designed to achieve maximum torque density and exceptional dynamic responsiveness within an ultra-compact mechanical envelope.

Baumüller’s DSC1 (Dynamic Synchronous Compact) series is celebrated across European manufacturing sectors for reducing motor volume by up to 30% compared to conventional servo designs in the same output class. This dramatic size reduction significantly lowers mechanical rotor inertia, unlocking extreme acceleration and deceleration rates while resolving tight spatial constraints in modern high-speed automated machinery.

Detailed Type Key Breakdown:
- DSC1-045: Frame size 45 (shaft center height 45 mm, square mounting flange ~70 mm).
- S: Short active magnetic stack length, maximizing the torque-to-inertia ratio for rapid start-stop positioning cycles.
- O: Surface-cooled via natural convection (Uncooled), eliminating mechanical cooling fans, preventing ambient particulate circulation, and lowering acoustic emissions in clean operating environments.
- 64U: Winding configuration 64 optimized for 540V DC bus voltage (400V AC mains), certified to international UL/cURus safety standards.
- 30 / 40: Rated speed variants:
  + Model -30-: 3000 RPM rated speed, tailored for robust, high-torque industrial automation tasks.
  + Model -40-: 4000 RPM rated speed, dedicated to high-speed dynamic cyclic operations requiring rapid linear feeds.
- 54: IP54 ingress protection rating for the motor housing (safeguarding against dust ingress and omnidirectional water splashing).
- EOA: Integrated 2-pole robust resolver feedback system (or precision optical encoder), providing exceptional resistance to severe shock, mechanical vibration, and elevated operating temperatures.
- DPP: Dual SpeedTec Intercontec industrial rotatable quick-lock plug connectors, ensuring fast, vibration-proof electrical wiring for both motor power and feedback channels.
- K: Drive shaft with DIN 6885-1 standard feather keyway, providing positive mechanical engagement and preventing shaft coupling slippage under shock loads.
- AN: Standard mechanical execution without an integrated holding brake, minimizing running drag and rotational inertia.
- O: Standard industrial protective surface paint in matte black.
- Factory Hardware Options:
  + Option -TC1: Embedded stator winding thermal protection sensor (PTC / KTY84 / PT1000) for real-time thermal overload prevention via drive monitoring.
  + Option +AS2: High-grade radial shaft oil seal ring (Simmerring / Viton seal), upgrading shaft sealing to IP65 to prevent gear oil ingress from coupled planetary gearboxes.

Key Engineering Features & Operational Advantages:
- Exceptional Torque Density: High-energy Neodymium-Iron-Boron (NdFeB) rare-earth permanent magnets combined with Baumüller's proprietary concentrated stator winding design yield a continuous stall torque (M0) up to 3.2 Nm and an instantaneous peak torque (Mmax) up to 3 to 4 times the rated value.
- Ultra-Low Cogging Torque: Optimized electromagnetic slot geometry virtually eliminates cogging torque, guaranteeing silky-smooth rotation at low operational speeds (down to a few RPM) without torque ripple or micro-vibrations, ensuring pristine CNC machining and print registration.
- Heavy-Duty Bearing System: Pre-lubricated deep-groove precision ball bearings rated for over 20,000 operating hours absorb significant radial and axial shaft loads from timing belts or spur gears.
- Seamless System Integration: Delivers peak performance when paired with Baumüller b maXX intelligent servo controllers (such as b maXX 3300, 5000, and 5500 series) via real-time industrial communication networks including EtherCAT, PROFINET, CANopen, and Ethernet/IP.

Typical Industrial Applications:
- High-speed flexographic, gravure printing, rotary die-cutting, and roll labeling machines.
- Automated stretch wrapping, plastic extrusion downstream equipment, and food packaging carousels.
- CNC mini-milling tool axes, precision feed drives, and automated tool changer mechanisms.
- Pick-and-place mechanisms, SCARA robots, and Delta kinematics in electronics manufacturing.
- Multi-station servo rotary indexing tables and automated transfer lines.
