42M048C Can Stack Stepper Mini Motor
42M048C
The 42M048C provides up to 11.9 oz-in (83.8 mNm) of holding torque. 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
