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.

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.

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.

The diagram shows that the closed loop stepper system will consume as little as a third of the power of a traditional step motor system when doing the same work.
