It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

Abstract: In this article, to improve the speed control performance of PMSM direct-drive servo systems under low-speed operation, a composite control strategy based on rotor position tracking control ...

Abstract: This article proposes a predefined-time synchronization and tracking control strategy for multimotor driving servo systems. First, a mean relative coupling synchronization controller is ...
