Design Features for SGMAH Sigma II


Compact

  • Small size motor is ideal for compact machine designs
  • High flux density neodymium iron boron permanent magnets reduce rotor size
  • 5 frame sizes with flange widths from 1.57 to 3.35 inches (40 to 85 mm)
High Performance
  • High torque-to-inertia ratio permits fast acceleration and deceleration reducing positioning time
  • Advanced magnetic circuitry and optimum winding geometry deliver very low cogging torque
  • Peak torque up to three times continuous torque
  • Peak torque can be maintained for up to three seconds
  • Rated speed of 3,000 rpm, max speed of 5,000 rpm
High-Resolution Serial Encoder
  • 8,192 ppr incremental encoder standard 1
  • 65,536 ppr absolute encoder optional 1
  • Amplifier automatically recognizes the motor and optimizes parameters
  • Error checking eliminates lost motion from electrical noise
Options
  • NEMA 23 and 34 Flange 2
  • Shaft Seal
  • Holding Brake

1 ppr is pulses or counts per revolution (post quadrature) or maximum resolution.
2 NEMA 23 and NEMA 34 flange motors have shaft diameters larger than typical NEMA dimensions due to servo application torques.
