Portescap DC Motors

Portescap disc magnet motors provide exceptional dynamic performance unparalleled by any other small diameter stepper in the market. The unique thin disc magnet enables finer step resolutions in a given envelope, significantly higher acceleration and greater top speed than conventional steppers.

These high speed stepper motors excel in applications that require the precision of a stepper and the speed and acceleration of a brushless DC motor. Closing the loop provides a competitive advantage against a servo solution.

• Precise - well-suited for microstepping
• Fast - disc magnet enables fastest acceleration and highest top speed of any step motor while maintaining accurate positioning
• Unique - low detent torque and highly customizable
• Adaptable - higher steps per revolution than similar diameter steppers

• Sintered or ball bearings
• Various windings
• Shaft modifications - increase/decrease length, knurling
• Longer leads, connectors
• Gearheads for increased torque

• Clinical Diagnostics
• Yarn Guides
• Pick and Place

• Laser cutters

• Wire cutting - EDM

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.

• 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 that can wear out

• Coil modifications – adjust resistance and inductance
• "Custom shafts – flats , knurling, diameter, length "
• Pinions and gears
• Special mounting flanges
• Wiring – connectors, lead length, shrink tubing
• Ball bearings, clutch magnets, dampers
• Magnets – to yield higher torque or reduced detent levels

• Dosing and Dispensing Systems
• Clinical Diagnostics
