Disc Magnet Stepper Motor Handles Rapid Acceleration Changes

The P760 series disc magnet motor from Portescap combines “Disc Magnet” technology and an optimized number of pole pairs to deliver 0.7-Nm torque and acceleration up to 5000 rpm. Disc Magnet technology provides very low inertia, and the pole-pair optimization balances the iron losses versus the joule losses—the rotor doesn’t require an additional iron structure to achieve flux variations. The closed-loop (thanks to an encoder) stepper motor’s inertia will drop to 17E-7 Kgm². Its dynamic performance meets an application’s needs for rapid changes in acceleration and direction of rotation. Such applications include electronic yarn guides, medical XY tables, robotics, and industrial automation.
