The smallest of our can stack stepper product line, the 15M020D provides .55 oz-in (3.87mNm) of holding torque in a 15mm frame size. It is optimal for low-torque positioning applications where size and/or weight is limited.

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

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
• Antenna Positioning
• Clinical Diagnostics
• Dosing and Dispensing Systems
• Humanoid Robot
• Printers and Copiers
• Switching Systems
• Valve Actuation
