步进电机是带有多个磁极的同步电机，因此可被看作是直接驱动装置。该电机具有保持扭矩大及定位能力卓越的X点。在全步和微步模式下，通过智能控制定子绕组可以直接获得（即无需回路系统）单步或多步。这使得步进电机和伺服电机不同，是一个非常经济的选择。过大的加速度和快速的负载循环会导致步进电机不再能够跟随旋转磁场和“失步”。在这种情况下，可以通过编码器选项加以改善。
步进电机在低速范围内扭矩X大，停止时有很高的保持扭矩。这样，在很多应用中，就无需保持制动。对于任何速度和负载，Beckhoff I/O 系统中的步进电机端子模块都可以存储相应的电流曲线，以把电机热负载调整到X佳状态。
Beckhoff 步进电机用作执行器或辅助轴。若与 KL2531 和 KL2541 型号的总线型步进电机端子模块、EL7031、EL7041 和 EL7051 型号的 EtherCAT 步进电机端子模块或 EP7041 步进电机端子盒及 TwinCAT 2 自动化软件配套使用，可以将经济高效的轴便捷地集成到所有应用中。
