Detailed content

  • Technical Specifications:
    • Frame:​ NEMA 34, 3.38 × 3.38 in flange
    • Step Angle:​ 1.8° (200 steps/rev), ±1.5 % accuracy
    • Supply:​ 36–320 VDC (typical 72 VDC chopper drive)
    • Current:​ 5.1 A parallel / 2.5 A series / 3.5 A unipolar
    • Holding Torque:​ 10.7 Nm (parallel), detent 0.35 Nm
    • Rotor Inertia:​ 2.7 kg·cm²
    • Shaft:​ Open keyway, SIGMAX lamination, Class B insulation, winding J
    • Leads:​ 8-wire (configurable bipolar/unipolar)
    • Radial/Axial Load:​ 289 N / 1360 N
    • Temp Range:​ -20 to +40 °C
  • Functional Features:​ High torque density, rugged heavy-duty end bell, optional encoder mount, compatible with microstepping drives.
  • Application Scenarios:​ Ball-screw actuators, rotary tables, valve control, legacy replacement for Superior Electric/Pacific Scientific.
  • Installation Requirements:​ NEMA flange bolts M5, avoid shaft radial load beyond 289 N, use 8-wire harness for bipolar series start.
  • Usage Notes:​ Not a servo motor—no closed loop unless encoder + closed-loop stepper drive added; de-rate holding torque if case exceeds 40 °C.
