When using a manual machine tool such as a lathe or milling machine, there can be a lot of pressure to read the position and feed the axes at the correct rate. That’s why modern machines typically ...

Stepper motor drive When a two-pole permanent magnet is used in the motor rotor, one full-step corresponds to a mechanical angle of 90 0. Each full step can be further divided into a number of ...

You probably know that if you spin a motor (mechanically) it generates electricity on what would normally be the inputs. This can be a problem when you shut off a spinning motor and is the reason that ...

A new motor driver featuring pulse-width modulation (PWM) and serial interfaces ensures quiet and robust motor operation in industrial and consumer applications. The motor driver IC, supporting both ...

The USB's many advantages have led designers to come up with a wide range of applications for the bus. For example, the figure shows a USB-based controller for four stepper motors built using ...
