The 20M020D provides up to 1.55 oz-in (10.95 mNm) of holding torque in a 20 mm frame size. The neodymium magnets provide high power density for applications that need moderate torque in a small package. 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
• Mechanical integration upon request (housing, front & rear flange, shaft)
• Pinions and gears
• Wiring - connectors, lead length, shrink tubing

Applications
• Clinical Diagnostics
• Valve Actuation
• Pharmaceutical Dispensing
• Robotic Applications
• Antenna Positioning
• Printers and Copiers
