To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...
