Product Short Description
Product Name: 6SM Series Brushless AC Servo Motor (High-Torque Variant)
Product Introduction: The 6SM77K-3000 is a frameless-style permanent-magnet synchronous servo motor from Kollmorgen’s 6SM family, built on a 77 mm frame (NEMA 42 class) with a high-torque, low-speed winding optimized for direct-drive and high-inertia load applications without gear reduction.
Description
Technical Specifications:
- Rated speed: 3000 rpm (mechanical)
- Rated torque: approx. 8.0 Nm (variant dependent, typical 8–12 Nm for K-winding)
- Peak torque: 30–50 Nm short-term depending on drive current
- Rated power: approx. 2.5–3.6 kW
- Rated voltage: 320–380 VAC (drive-dependent)
- Feedback: resolver or absolute encoder (EnDat/Hiperface, suffix dependent)
- Protection: IP64/IP65
- Optional: 24 VDC spring-applied holding brake
Functional Features: High pole-count design for low-speed high-torque output, low cogging, rare-earth magnet rotor, vacuum-impregnated stator, PTC thermistor winding protection, sealed bearings rated for continuous duty.
Working Principle: Standard three-phase brushless PMSM operation under closed-loop servo control; rotor position is fed back to the drive which commutates the stator field to maintain torque and speed commands.
Application Scenarios: Large rotary indexing tables, radar antennas, centrifuge drives, heavy mixer agitators, wave-compensation platforms, CNC rotary axes.
Structural Characteristics: Square 77 mm flange, surface or interior permanent-magnet rotor, laminated stator stack, rotatable connector or lead exit per suffix.
Installation Requirements: Flange or foot mounting with shaft alignment error below 0.1 mm; adequate clearance for heat dissipation; shield feedback and power cables separately.
Usage Notes: Do not run at peak torque continuously; observe PTC trip threshold (~130 °C); verify encoder compatibility with drive before commissioning; braking option mandatory for vertical-axis loads.
