- “MSK”: Product family identifier, representing “High-Dynamic Synchronous Servo Motors” — specialized in high torque density and ultra-low backlash, differentiated from asynchronous motor series like “MAK”.
- “030C”: Frame size & cooling type: “030” denotes a 30mm compact frame diameter (optimized for space-constrained applications); “C” indicates “Convection Cooling” (air-cooled, no external fans, suitable for low-to-medium load scenarios, vs. “W” for water-cooled high-load models).
- “0900”: Rated torque code: “0900” corresponds to a rated torque of 0.9 N·m (direct reading of core performance, avoiding complex conversions).
- “NN”: Feedback device code: “NN” means “No Encoder Pre-Installed” — supports flexible integration with incremental/absolute encoders (e.g., Bosch Rexroth ROD 430 or Heidenhain EQN 1325), adapting to diverse position/speed feedback needs.
- “M1”: Shaft configuration code: “M1” specifies a standard solid shaft (6mm diameter, smooth surface) with a keyway (for secure coupling), differentiated from “M2” (hollow shaft) or “M3” (specialized threaded shaft).
- “UP1”: Special feature code: “UP1” indicates “High-Precision Bearing Assembly” — enhanced radial/axial runout accuracy (≤0.005mm) and extended bearing life (20,000+ operating hours), optimized for precision machining.
- “NSNN”: Customization code: “NSNN” denotes a standard configuration (no additional options like brakes or special coatings); “B” would indicate a holding brake, “S” for stainless steel shaft, etc.
- Core positioning: Serves as the “precision motion execution unit” in systems like CNC micro-machining tools, robotic assembly arms, and electronic component placement machines — delivering sub-millimeter positioning accuracy and high dynamic response.)
2. Product Description
2.1 Compact Design with High Torque Density
2.2 Ultra-Precision Motion Control
- Speed stability: ≤±0.05% fluctuation at rated speed (3000 rpm), ensuring consistent cutting force for micro-machining.
- Positioning accuracy: ≤±0.003mm (when paired with a 1μm-resolution encoder), meeting strict tolerances for optical component manufacturing.
- Backlash: ≤0.001 rad (mechanical hysteresis), eliminating motion lag in closed-loop control systems (e.g., robotic arm joint positioning).
2.3 Flexible Integration & Compatibility
2.4 Industrial-Grade Reliability
- Housing: Anodized aluminum alloy (corrosion-resistant, IP65 protection for the motor body; IP54 for the connector).
- Windings: Class F insulation (max operating temperature: 155°C), withstanding ambient temperatures of -20°C to +40°C.
- EMI Compliance: EN 61800-3 (industrial environment immunity), resisting interference from nearby inverters or power supplies.
This ensures 24/7 continuous operation in harsh industrial environments (e.g., dusty electronics factories, temperature-fluctuating lab automation setups) with a Mean Time Between Failures (MTBF) of ≥30,000 hours.
