Disc Magnet MOTORS

These high-speed micro stepper motors excel in applications that require the motion precision of a stepper motor and the speed and acceleration of a brushless DC motor. These unique disc magnet stepper motors are great for mobile applications, devices with size limitations and applications requiring fast and precise positioning. With the highest torque to inertia ratio, you can't go wrong!


The exceptional possibilities offered by our line of disc magnet stepper motors are unequaled by any other kind of permanent magnet stepper motor. Their advanced technology, developed by Portescap in Switzerland, allows for truly exceptional dynamic motor performance. The unique thin disc magnet enables finer step resolutions than permanent magnet stepper motors in a given envelope, significantly higher acceleration due to low inertia and greater top speed than conventional steppers due to a shorter magnetic circuit presenting lower iron losses. Therefore, these stepper motors are ideal in applications that require fast incremental motion. This unique design takes full advantage of new rare earth magnets and features:
  • Low moment of inertia resulting in outstanding acceleration and high start and stop frequencies
  • Short magnetic circuit allowing high motor speed and current boost capabilities
  • Specific magnetization method gives smaller step angles than conventional permanent magnet stepper motors
  • Optimized package size yields incremental movement in the shortest possible time
  • Unique low detent torque and increased efficiency over other stepper motors
  • Highly customizable and available in diameters starting at 10 mm up to 91 mm
