Typical closed-loop stepper-motor systems include a complicated controller or pulse generator. The controller senses the encoder or resolver feedback and does the comparing.

Like other PCB motors it produces very little torque, roughly 2% of a typical NEMA17 stepper motor. Even so, the engineering behind this project remains impressive.

Stepper motors have several attributes. They generate incremental motion and generally run open-loop, and this eliminates the cost and complexity of an encoder or resolver.

JVL QuickStep closed-loop integrated stepper motors provide higher torque, faster acceleration, torque control, stall free operation and quieter movements than traditional step motor systems.
