DSP controllers and sensorless algorithms provide the key for implementing inexpensive closed-loop control on stepper motors. The high performance and integration found in DSP-based controllers enable ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
