42M100B Can Stack Stepper Mini Motor

42M100B Can Stack Stepper Mini Motor

42M100B

42M100B provides up to 7 oz-in (49.4 mNm) of holding torque. The 100 steps per revolution results in a 3.6 degree step angle which provides fine positional resolution.

Product Highlights

  • Excellent open loop control - no encoder necessary
  • Digitally controlled - easy to use with a micro processor
  • Cost effective - compact design, lower integration cost
  • Maintenance free - no brushes to replace
  • Unipolar and bipolar winding options

Customization Available

  • Ball bearings, clutch magnets, dampers
  • Coil modifications - resistance and inductance
  • Custom shafts - flats, knurling, diameter, length
  • Magnets - to yield higher torque or reduced detent levels
  • Mechnical integration upon request (housing, front & rear flange, shaft)
  • Pinions and gears
  • Wiring - connectors, lead length, shrink tubing
