Portescap has recently introduced the P532 Series Disc Magnet Step Motor with encoder to deliver best-in-class motor acceleration and power rate and thus outperform the standard Brushless DC motor in a wide range of applications.
Stepper motors typically run at 2,000 RPM or less in an open loop, while brushless motors that can run at much higher speeds are typically used in closed loop applications. In the last few years, trend is to use a stepper motor in closed loop with a torque higher than a brushless motor system, because of its higher pole count. What we are typically looking at is the middle range of revolutions per minute [RPM] as a sweet spot for disc magnet motors. The sweet spot opens up in applications in the few thousand RPM range, where a closed loop disc magnet motor system can be more cost-effective than a brushless solution.
