42L048D Can Stack Stepper Mini Motor

42L048D

The large rotor and neodymium magnets of the 42L048D provide up to 18.5 oz-in (131 mNm) of holding torque and is optimal for high torque applications. The 48 steps per revolution results in a 7.5 degree step which increases the positional resolution. It is available in 5 or 12 volt windings, and in unipolar or bipolar designs.

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
