SGMBH Sigma II

Specifications & Features

Features

Compact

  • Internal Permanent Magnet (IPM) construction reduces rotor inertia and permits high speeds
  • High flux density neodymium iron boron permanent magnets reduce rotor size
  • 3 frame sizes with flange widths from 9.84 to 13 inches (250 to 330 mm)

High Performance

  • High torque-to-inertia ratio compared to induction servo designs
  • Skewed magnets reduce cogging torque for smooth motion at low speed and short settling times
  • Medium inertia rotor is ideal for optimized load matching
  • Peak torque can be maintained for up to five seconds
  • Rated speed of 1,500 rpm, max speed of 2,000
