The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

Not missing a beat: Here we take a look at why open-loop steppers lose steps, as well as some solutions to the problem. As in the below) half-stepping produces eight steps per electrical rotation — ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.
