As an encoder, a stepper motor has nothing absolute. There is no stop, no indicator of position, you have to count steps and direction to give a sense of anything. As a motor, it works tge same way.

Conventional peak current control stepper motor drivers rely on detecting peak current only ... inexpensive, peak-current-control, bipolar, stepper motor drivers. A block diagram of the MP6500 is ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rot… ...

While open-loop SMLA systems are suitable for many applications, stepper motor users wanting real-time feedback on load position should consider adding encoders to their motors. Encoders can provide ...
