P760 with Encoder

P760 Stepper Disc Magnet Motor with Encoder

P760 EN Disc Magnet High Speed Step Motor

P760 EN

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.

Product Highlights

  • 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

Customization Available

  • Coil modifications - resistance and inductance
  • Custom shafts - flats, knurling, diameter, length
  • Gearheads for increased torque
  • Sleeve or ball bearings
  • Wiring - connectors, lead length, shrink tubing
