Product Short Description
Product Name: 6SM series extended-stack brushless synchronous servo motor, frame 37 VL, 6000 rpm
Product Introduction: Higher-torque, high-speed variant of 6SM37 with longer VL stack, delivering 1.2 kW at 6000 rpm for fast cyclic positioning.
Technical Specifications:
- Rated power: 1.2 kW
Description
- Rated speed: 6000 rpm
- Rated torque: 2.0 Nm, standstill torque 3.0 Nm
- Rated current: 2.8 A rms, peak 15.2 A
- Torque constant: 0.79 Nm/A, back-EMF 48 mV/min
- Resistance: 3.65 Ω, inductance 8 mH
- Protection: IP64, Class F insulation
- Feedback: Resolver standard, encoder optional
- Brake: 24 VDC holding brake on -G suffix variants
- Weight: ~3.5–4.2 kg
Functional Features: Extended stack for ~double standstill torque vs 6SM37L, 6000 rpm ceiling, low inductance for fast current loop, compatible with SERVOSTAR CD/S300/S600.
Application Scenarios: High-speed spindle servo, semiconductor wafer transfer, foil/web cutoff, rapid indexing presses.
Working Principle: Same PM synchronous principle as 6SM37L but with larger magnetic stack; drive commutates based on resolver angle at elevated electrical frequency to sustain 6000 rpm.
Installation Requirements: Reinforce mounting for higher reaction forces at speed, balance coupling for 6000 rpm, use drive with ≥15 A peak rating, brake wiring separate 24 VDC if -G.
Usage Notes: Bearings limited by high-speed grease life; derate if sustained 6000 rpm under load; brake releases only with 24 VDC applied.
