Permanent & Disc Magnet Stepper Motors

P010 104 Disc Magnet Stepper Motor

Disc Magnet Stepper Motor

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. Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including gearboxes and wiring / connector options please contact our sales and applications support team.

Motor 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
